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 operating situation because the motion was shielded from water and grime 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 trendy tech and supplies.
Pulling any be careful of the ocean and nonetheless discovering it to be operating 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 principally for brief durations of time solely. Being underwater for years on finish is one thing watches are simply not alleged to do, so kudos to Citizen for constructing a watch way back to 1977 that would.
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 trendy tech and supplies, a barely decreased peak and is ISO 6425 compliant.
The brand new Citizen Promaster Mechanical Diver 200M is totally fabricated from Tremendous Titanium, one thing Citizen is aware of do very properly. 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 fabricated from titanium, again in 1970. This was at a time when the fabric was primarily being utilized in area 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 inexpensive 41mm in diameter and 12,3mm in peak. The best way it’s constructed it looks like the bezel is barely wider than the center case, however each have the very same width. It does present for an attention-grabbing visible enchantment, 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 fantastic deal in a device that would doubtlessly save your life.
The dial is available in both black or blue, with embossed rectangular indices. Every is stuffed with a great dose of luminous materials in a retro inexperienced hue. It has fairly a powerful glow, which may be seen in the course of the day as properly 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 provides 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 blue model. ref. NB6021-68L.
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 value for each fashions is but to be confirmed on the time of publication however can be included as soon as identified. It will likely be obtainable from Summer time 2022.
Whichever method you have a look at these watches, which I’ve finished some time now, it’s laborious to disregard the rock-solid proposition. The watch seems to be good, feels nice on the wrist, and delivers a stable efficiency in key areas. Every little thing feels sturdy regardless of the low weight, and it’ll certainly 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.
