Each time the subject of horological issues comes up amongst WIS, they appear to like mentioning which issues are their favorites or – to get the talk going – which one is the perfect. Individuals love a debate (NOT) and like to flex horological data.
The same old suspects present up among the many favourite helpful issues: an influence reserve on a handbook wind motion for its crucial function in stopping a watch from winding down; the perpetual calendar for its excessive longevity earlier than needing to be adjusted; the GMT for the enterprise traveler crossing time zones and doing enterprise internationally; and the finally practical chronograph for its huge number of timing makes use of.
Somebody may say that the perfect complication is the tourbillon as a result of it was invented by Abraham-Louis Breguet, the patron saint of Swiss watchmaking. It will undoubtedly be challenged as many don’t think about the tourbillon a complication – and in most tourbillon wristwatches its usefulness is significantly doubtful anyway.
However in each debate, there are issues that don’t get talked about just because they lack huge acclaim as being very helpful to the trendy watch aficionado.
You most likely gained’t hear somebody make the case for the astrolabe dial or reward the native photo voltaic time indication.
Positive, the moon section might need its followers (me amongst them), however folks aren’t actually claiming it has a crucial fashionable operate for anybody aside from a technology-averse fisherman who must know the tides.
Nonetheless, the case could possibly be made for all of those being practical to sure segments of the society, even whether it is comparatively slim.
However there are positively a number of issues which have dramatically little to no use for nearly any person, particularly with regards to making the watch extra practical, correct, or versatile. Such issues are a novelty amongst novelties and have a tendency to solely present up on grande issues or watches vying for the title of most complex watch.
However in the actual world, a few of these issues are fairly ineffective. Don’t suppose I’m saying they aren’t cool, as a result of they’re. Every complication that has little actual world utility continues to be fairly darn superior for some technical motive, and at this time I wish to run via what I feel could be the highest 5 most “ineffective” issues. Instantly adopted by why they’re superior and should be seen in watches extra!
So let’s get the ball rolling and depend down from my first choose for least helpful complication.
No. 5: gyroscopic stability module
Just like the tourbillon, you most likely shouldn’t name this a complication as a result of it doesn’t add a operate. I’m getting that out of the best way first.

A detailed have a look at the Zenith Defy Zero G’s gyroscopic stability module
The gyroscopic stability module is a really uncommon characteristic, solely present in Zenith watches such because the Defy Zero G, and there have solely been a handful of editions over the previous decade or so.
The concept is that the stability and escapement are mounted in a gyroscopic gimbal that may rotate in any path whatever the place of the watch. It supposedly retains the stability completely flat in order that it may get rid of the results of gravity on a stability continually altering orientation.
The one drawback is that it could be onerous to show that it really works in the actual world as a result of a gimbal that small merely can’t work as meant. The load is just too close to the pivot factors, so as a substitute of a steadicam-like movement, you get one thing akin to a whirling rotor, however in each path.

Zenith Defy Zero G on the wrist
I’ve seen this in motion, and it merely spins willy nilly as a result of the load can’t preserve it completely degree except the watch is barely transferring. The one means it may work could be if the load was produced from a nugget of neutron star, in any other case it’s simply going to flail round and never present any actual stability.
However that doesn’t imply the engineering behind it isn’t spectacular!

View via the show again of the Zenith Defy Zero G with the Gravity Management escapement module on the left
The mechanism needed to permit the stability and escapement to be continually pushed with adequate torque by way of a fancy set of differentials permitting it transfer in any path at any second. No simple job. And the newest model noticed a serious discount in dimension, that means that it’s much more extremely complicated to engineer and assemble.
Too dangerous that it most likely does little or no for what it’s imagined to do, however I completely find it irresistible nonetheless.
No. 4: chronographs correct to 1/a thousandth of a second
The chronograph is arguably some of the helpful issues in watchmaking. It permits for exact management over the motion and the power to time issues all the way down to a fraction of a second, some even permitting splits, on-the-go flyback, and high-frequency timing.
However the one which enters into the realm of ineffective is the 1/a thousandth of a second chronograph, most famously exemplified by the TAG Heuer Mikrotimer Flying 1000.

TAG Heuer Mikrotimer Flying 1000
The rationale it’s ineffective comes all the way down to biology: human response time is, on common, round 0.25 seconds, presumably as much as 0.15 seconds in supreme situations. Did you see how that was measured? With two decimal locations as a result of something extra is leaving the realm of serious figures.
Human response time is rarely quick sufficient to wish something greater than 1/one hundredth of a second precision, and in a majority of circumstances something over one-tenth of a second might be too wonderful to actually distinguish for most individuals.
The extent of precision in a 1/a thousandth of a second chronograph is for no different function than as a result of they’ll: no human can benefit from the wonderful graduations after one considers all of the elements concerned in reacting and pushing a button.
However who cares! The engineering behind such a mechanism is the unimaginable half: getting parts to maneuver that quick . . . beginning and stopping and beginning once more is significantly onerous on the tiny parts.
The forces engineers needed to overcome had been vital, together with challenges associated to energy consumption, lubrication, and the excessive precision tolerances obligatory.
Positive, you’ll be able to’t benefit from it in any considerable means, however you’ll be able to watch it fly across the dial and faux such as you truly tried to cease it at a unique level every time as a substitute of it being extra the results of the interactions of the parts and your sluggish organic processes.
No. 3: date of Easter
Christians make up 30 p.c of the human inhabitants, so clearly lots of people would love to pay attention to the date of Easter, one of many faith’s most necessary holidays. However since solely a handful of machines have ever been created to routinely show this date, it clearly wouldn’t be reaching its meant viewers.
And since we all know the moon phases for the following few millennia resulting from astronomers calculating this, and we all know find out how to depend, we additionally know the precise days of Easter for an extended, very long time.
This complication’s meant use is remarkably slim and positively not obligatory.
However what’s attention-grabbing is that the date of Easter is without doubt one of the most troublesome mechanical issues in horology because of the variability that comes from how it’s calculated. This makes it a long-time holy grail (pun meant) of mechanical issues.
The date of Easter is predicated on the lunisolar calendar (moon phases relative to the time of the photo voltaic 12 months) and is the primary Sunday after the complete moon that comes on or after March 21 – that means it may fall anyplace from March 22 to April 25.
So the date of Easter requires combining a perpetual calendar and an correct moon section merely to calculate the hopscotching Sunday of Easter.

Patek Philippe Caliber 89 in yellow gold
As I discussed, crafting a mechanical complication for this isn’t a straightforward job and one exhibiting why it’s not often ever tried. The calculation is called the Comptus, and so far as I do know only a few clocks in historical past have built-in it, and just one watch: Caliber 89 by Patek Philippe.
Konstantin Chaykin made a clock with the date of Easter, although this was additionally a really sophisticated four-sided clock with tons of issues. Creating an Easter date complication is a ton of labor, and blatantly not obligatory.

Konstantin Chaykin Moscow Comptus Clock
Oh, and what makes it much more troublesome? Completely different teams of Christians (specifically the Jap Orthodox, Oriental Orthodox, Anabaptists, and Christian Berbers) use completely different calendars to calculate Easter, particularly the Julian calendar (versus the Gregorian calendar everybody else makes use of), which places the date 13 days later than the western (Gregorian) date.
So even in the event you construct a complication for one, it could be off for the opposite except you added one other complication to show the distinction.
Whereas this can be very restricted in its use, the mechanical resolution is extremely troublesome and supremely cool. After all I’ll nonetheless simply use my cellphone’s calendar.
No. 2: hidden/on-demand time show
The hidden-time show, in any other case often called time on demand, is a gaggle of issues that preserve both the minutes or hours, or each, hidden from view or from being displayed till a pusher is pressed – or in a single case, till the watch is oriented in a really particular means.
The complication is commonly used as a playful tackle the time show or as a method to get you to cease specializing in the time in a busy world. Relying on the iteration, you might not even see the palms till the mechanism is activated and so they spring out to indicate you the time.

Genius Temporis by Konstantin Chaykin
An attention-grabbing tackle this comes from Konstantin Chaykin, who created the Genius Temporis, a watch with a single (double-ended) hand that shows the present hour with the big finish of the hand. When a pusher at 2 o’clock is pressed, the hand spins round till the small finish involves level on the present minutes.

Maurice Lacroix Aikon Mercury Solely Watch 2019
The tactic for creating this variable on-demand show can differ for each single watch that features one. Maurice Lacroix not too long ago launched the Aikon Mercury by which the hour and minute palms spin freely always till the watch is held completely upright while you see the palms spin into the right place to show the present time.
Clearly, this mechanism, whereas thematically much like the Genius Temporis, is dramatically completely different in design and performance.
One other variation is a time show that may change to show one thing else earlier than returning to displaying the present time.

Van Cleef & Arpels Girl Arpels Pont des Amoureux ‘Spring’
Van Cleef & Arpels has an instance of this with the Agenhor-engineered Pont des Amoureux, the place the time is displayed by way of two figures slowly climbing an arched bridge to fulfill within the center and kiss at midday and midnight.
The time is at all times displayed, however you’ll be able to activate the midnight kiss on demand due to a pusher at 8 o’clock. Functionally, this is similar intent because the time on demand, however in reverse; it additionally reveals the mechanical creativity potential with such a complication.
But when we’re speaking about how helpful hiding the time is, I can’t provide you with many sensible causes for it outdoors of protecting somebody from being distracted by not permitting her or him to at all times test the time.
This can be a laudable use for the appropriate folks, however I might enterprise that hardly anybody would wish a watch like that for that particular motive. And one may argue {that a} pocket watch could be a greater and simpler resolution of protecting the trip of simple view.
However, actually, it doesn’t really feel like there’s any sufficiently legitimate motive to have the complication aside from as a result of it’s attention-grabbing and playful.
Mechanically, these are form of a smorgasbord of artistic options, each offering one other method to obtain the identical objective. However like others on this checklist, I don’t suppose there’s an goal motive for greater than a handful of individuals to ever want one thing like this.
And at last we attain the complication that I imagine is essentially the most ineffective complication present in a watch at this time.
Drumroll, please . . .
No. 1: foudroyante seconds
Until you’re a complication nerd into each sort of mechanical complication and really effectively versed within the odd, you a lot not initially even know what that is. And that’s my first piece of proof supporting its utter uselessness.

Jaeger-LeCoultre Duomètre à Chronographe
The foudroyante is a hand displaying every particular person tick of an escape wheel, normally by a wheel that meshes with one other toothed wheel hooked up to the escape wheel.
This foudroyante wheel may have the identical variety of enamel because the beats per second of the stability, so one rotation of the gear equals precisely one second. This creates a blazingly quick hand that races in circles, however stops fully with each tick, inflicting a hand that appears like a super-low framerate animation of a spinning hand.
The technical challenges accompanying the foudroyante embody fast energy consumption, introducing vital timing inaccuracies, and requiring a really effectively balanced and light-weight hand to stop put on or drag on the escapement (a part of these timing inaccuracies).
It’s an odd factor to observe, considerably disconcerting as a result of it covers a lot distance however stops fully with each beat of the stability. Not like a sweeping second hand or the useless second show, it doesn’t have a lot use as a result of it merely strikes too darn quick.

F.P. Journe Centigraphe Souverain Anniversaire
Visually it’s extremely spectacular, and I might say rivals a high-speed chronograph hand or a tourbillon for a characteristic destined to seize the eye of these glancing at your watch.
Something transferring that quick is sure to seize the gaze, nevertheless it actually lacks a lot in usefulness. That’s except it’s discovered on a chronograph and might be stopped. And that is exactly the place one may discover a foudroyante: as a fraction-of-a-second show for a chronograph operate.
And whereas this may assist to find out the fractions of a second that you simply measured, the common chronograph second hand may also be capable of show this, albeit in a smaller and presumably harder-to-read format, however nonetheless as a typical characteristic of a chronograph.
So the foudroyante is commonly an addition that isn’t solely obligatory in that context, despite the fact that it technically is sensible.
But it surely isn’t at all times used at the side of a chronograph, and in that occasion I can discover no justification for its presence outdoors of being a unusual feat of mechanical watchmaking. The show strikes too quick to be learn; it’s extra of a visible illustration of the escapement than something.
Watches that includes a foudroyante chronograph embody the Habring Foudroyante Felix, the Jaeger-LeCoultre Duomètre à Chronographe (a semi-useful iteration), and the F.P. Journe Centigraphe Souverain (one other chronograph).

The engaging Breguet Classique Chronométrie Reference 7727
“Foudroyante” is usually known as “flying seconds,” although I personally would say that the identify flying seconds ought to check with one thing completely different, particularly the semi-foudroyante, which shows the quickly transferring second hand however with a rotational interval of multiple single second.
Some high-frequency chronographs do that, displaying six seconds or ten seconds in order that the show is much less jarring. That is additionally discovered on the Breguet Classique Chronométrie 7727, which incorporates a two-second subdial that makes 20 distinct stops in a single rotation. However because the subdial is so small, the space between every cease is miniscule, making it seem a lot smoother and missing the dramatic show of a real, one-second foudroyante.
And that’s, for my part, why it’s included on any chronograph or common wristwatch: drama.
The lightning pace (which by the way is the origin of the identify: “foudre” is French for “lightning”) of the beginning and cease, 5 to 10 occasions a second, could be very alluring. However additionally it is very negligible to the usage of the watch, and except it’s the solely measurement of the fractions of a second on a chronograph, it’s superfluous – put there merely to make studying the fraction displayed elsewhere extra visually pleasant.
And for that motive, I feel it’s the most ineffective complication in a wristwatch, and concurrently why it’s so dang cool.
It has little or no motive to exist because it does and makes the motion weak to many points due to its inclusion, however tickles my visible cortex so exactly that I’ve to cease and ogle.
I imply, because of this we get into mechanical watches within the first place: they’re, as a class, wholly impractical and pointless due to technological advances over the past century. However they do cool issues and that makes us smile, so I suppose it’s even.
