In 1983, a Citizen Problem Diver from 1977 was recovered from an Australian seaside. The watch was coated in barnacles, indicating it had been underwater for fairly just a few years, as these slowly construct up over time. Surprisingly, it was nonetheless in working situation because the motion was shielded from water and filth by its case. This fascinating little story serves as inspiration for Citizen’s newest dive watch, the Promaster Mechanical Diver 200M NB6021, which comes with fashionable tech and supplies.
Pulling any be careful of the ocean and nonetheless discovering it to be working after a few years in one of many harshest environments possible, is a testomony to its building. Naturally, that’s what divers are supposed to have the ability to face up to within the first place, however largely for brief intervals of time solely. Being underwater for years on finish is one thing watches are simply not speculated to do, so kudos to Citizen for constructing a watch way back to 1977 that might.
It additionally serves because the backstory, and inspiration behind Citizen’s newest, the Promaster Mechanical Diver 200M NB6021. This pair of humble little divers is modelled after the Problem Diver from 1977, as discovered on that Aussie seaside. Therefore, it has a pleasent retro-look and modest dimensions just like the unique. It has been up to date in key areas although, with fashionable tech and supplies, a barely diminished peak and is ISO 6425 compliant.
The brand new Citizen Promaster Mechanical Diver 200M is totally product of Tremendous Titanium, one thing Citizen is aware of methods to do very effectively. The light-weight materials is handled with the model’s proprietary Duratect hardening know-how to create an ultra-resilient, scratch-resistant floor. Citizen was the primary producer to supply a commercially obtainable watch product of titanium, again in 1970. This was at a time when the fabric was primarily being utilized in house and aeronautical industries. Over time, Citizen’s experience led to the introduction of Tremendous Titanium, a registered trademark combining the model’s titanium processing applied sciences and Duratect floor hardening course of.
The case measures an affordable 41mm in diameter and 12,3mm in peak. The best way it’s constructed it looks as if the bezel is barely wider than the center case, however each have the very same width. It does present for an fascinating visible attraction, additional enhanced by the brushed ending on the case and the polished outer floor of the bezel. This has a black or blue insert with a crisp silver 60-minute diving scale and a luminous pip contained in the triangular indicator. It grips simply and turns with a reassuring really feel and a clean “click on”. Its alignment is spot-on, one thing that issues a terrific deal in a instrument that might probably save your life.
The dial is available in both black or blue, with embossed rectangular indices. Every is full of dose of luminous materials in a retro inexperienced hue. It has fairly a powerful glow, which could be seen through the day as effectively when correctly charged by direct daylight. Time is indicated by a Mercedes-style hour hand, a sword-shaped minute hand and a lollipop seconds hand. Once more, all are handled with the identical inexperienced glowing luminous materials. It’s coated with a flat-top sapphire crystal, with a bevelled edge and a domed underside. The date window cuts into the three o’clock index and is printed in white.
Energy comes from Citizen’s in-house produced Calibre 9051, which we’ve already seen within the Promaster Mechanical Diver 200M NB6004 and the Collection 8 831 Mechanical NB6010 and NB6012. This computerized motion runs at a frequency of 28,800vph and makes use of 24 jewels. It gives a good 42h energy reserve and is regulated to run inside -10 to +20 seconds of deviation per day. As we’ve realized earlier than, this motion is anti-magnetic to fields as much as 16,000A/m (approx. 200 Gauss) as shut as 1cm away, which is actually reassuring. The motion is hidden from view by a stable titanium caseback.

The Citizen Promaster Mechanical Diver 200M NB6021 is introduced with two strap choices. The black dial (ref NB6021-17E) is offered on a black rubber strap with a waffle-like embossing and titanium pin buckle. The blue dial model (ref. NB6021-68L) comes on a Tremendous Titanium three-link bracelet with a folding clasp. The worth for each fashions is but to be confirmed on the time of publication however will likely be included as soon as identified. It is going to be obtainable from Summer time 2022.
Whichever manner you have a look at these watches, which I’ve executed some time now, it’s arduous to disregard the rock-solid proposition. The watch seems good, feels nice on the wrist, and delivers a stable efficiency in key areas. All the pieces feels sturdy regardless of the low weight, and it’ll absolutely not disappoint on leisurely jumps within the pool, the occasional leisure dive or in any other case. It’s only a good, no-nonsense, ISO 6425 compliant dive watch, interval.
