As an organization based by a flight teacher and pilot in 1961 – Herr Helmut Sinn – you possibly can anticipate extremely engineered watches constructed with performance, reliability, and endurance in thoughts. And, for a lot of the fashions out there in Sinn Spezialuhren’s portfolio, it’s the case. And much more so on the subject of the emblematic Einsatzzeitmesser collection of watches or EZM – an idea referring to Mission Timer watches and launched in 1997. Since then, we’ve seen a number of fashions below this acronym, the most recent being the EZM 13 of 2014. Discontinued for some time, the signature, overly examined, ultra-engineered diving chrono with a 60-minute show and left-handed look is again with the model new Sinn EZM 13.1 Diving Chronograph.
Sinn’s Einsatzzeitmesser, a collector’s favorite
The EZM watch by Sinn – which stands for Einsatzzeitmesser and could be translated into mission timer – is, along with the U1 dive watch and the 104 pilot’s watch, some of the revered and sought-after watches produced by the Frankfurt-based producer. Born within the late Nineties, this veritable device watch fused the concept of a dive watch with a chronograph in an ultra-clear and purposeful look.

The EZM 1, the unique one in all 1997, was the cleanest of all of them, utilizing two central chronograph palms (for the seconds and minutes) and no sub-counters. It had a 60-minute pilot’s countdown bezel, a titanium case, and a left-sided profile with a crown and pushers at 9 o’clock. Inside was a Lemania 5100, and following the tip of its manufacturing, the watch was discontinued within the late 2000s. It was initially designed for particular German Customs Forces and later turned out there to most of the people. Since then, the model launched the EZM 3, a extra basic (no chronograph) dive watch, and the EZM 13 in 2014. We’ve missed the latter for some time, but it surely’s again in 2022 with minor updates throughout.
The brand new Sinn EZM 13.1 Diving Chronograph
To start with, relaxation reassured… The unique idea of the Einsatzzeitmesser watch remains to be properly alive. Second, the brand new EZM 13.1 shouldn’t be that far-off from the earlier technology and takes on all of the basic (and beloved) components, including a couple of updates – however we’re speaking minimal ones.

As you possibly can see above, the brand new Sinn EZM 13.1 Diving Chronograph is barely marginally totally different from the previous EZM 13. As you possibly can guess by the title of this re-creation, we’re speaking mid-life cycle replace, kind of a facelift that primarily focuses on dial legibility. The fundamentals – diver x chronograph, bezel, destro case, motion, and magnificence – are all current.
The case of the EZM 13.1 retains the unique proportions of a 41mm diameter and a 15mm top – not too giant truly for an computerized chronograph with 500m water-resistance. The chrome steel is bead-blasted for a matte, anti-reflective look, and the watch retains the identical specs: sapphire crystal with double-sided AR coating; left-positioned screw-down crown and pushers with D3-System; screwed caseback; rotating bezel with black aluminium insert and 60-minute scale; and 50-bar strain resistance. And since it’s a Sinn watch made for motion and particular forces, the record of requirements and necessities it meets and of applied sciences used is lengthy, like actually lengthy. We even needed to create two new sections within the specs on the finish of the article particularly for this watch. It’s all about resistance to strain, temperature, fogging, magnetic fields, in line with assessments by DNV and norms by DIN. Totally packed is essentially the most correct factor I can say about this watch.
The principle replace regarding this new Sinn EZM 13.1 Diving Chronograph is the dial, which eliminates the Arabic numerals on the 12h scale and now solely options basic markers for the hours. In any other case, the show stays the identical, with central hours and minutes, a small seconds at 3 o’clock, a crimson date at 4:30, a small AR emblem (a navy reference) at 9 o’clock and the principle specificity, a 60-minute sub-counter for the chronograph – as a substitute of a 30-minute counter on most 7750-based watches. All components are extremely contrasting and coated in luminous materials.
Underneath the metal caseback is the Sinn chronograph motion SZ02, a modified computerized Valjoux 7750 with 26 jewels, a 4Hz frequency and about 45 hours of energy reserve. The Sinn EZM 13.1 will probably be out there on a bead-blasted metal bracelet with a folding clasp, on a black rubber strap, or a leather-based strap (a number of choices out there).
Availability & Worth
The Sinn EZM 13.1 Diving Chronograph will probably be out there from Might 2022 and may now be pre-ordered on the model’s web site. Costs vary from EUR 2,650 on straps to EUR 2,850 on a metal bracelet. Not per se an affordable watch, however contemplating the extent of engineering that goes into this watch, the modified motion, the considerably quirky look, and the sheer cult standing of the EZM collection of watches, it stays fairly a good value, for my part, for what is likely one of the model’s final instrument watches!
