Citizen Promaster Eco-Drive Professional Diver 1000m Watch

Citizen Promaster Eco-Drive Professional Diver 1000m Watch Watch Releases

At Baselworld 2017, Citizen watches of Japan will release what is the most durable dive watch I’ve ever personally known them to produce in the Promaster Eco-Drive Professional Diver 1000m timepiece. Citizen also makes the claim that it is the most water-resistant dive watch (and first 1000-meter Eco-Drive) that is light powered, allowing it to go deep within the ocean where no natural light exists to power the movement – a minor irony. Fans of Japanese tool watches will delight, though this professional-themed diving tool watch comes at a not-insignificant price.

Citizen Promaster Eco-Drive Professional Diver 1000m Watch Watch Releases

The Citizen Promaster Eco-Drive Professional Diver 1000m (reference BN7020-09E) has indeed been developed as a professional diving timepiece. As a saturation diver, this Citizen Promaster is designed to survive long periods of time in decompression chambers and also contains an automatic helium release valve on the side of the case near 10 o’clock. The accumulated features in the Citizen Promaster BN7020-09E are designed to make the watch both durable, safe, and wear-resistant.

There are at least two innovations in the Citizen Promaster Eco-Drive Professional Diver 1000m that the brand is proud of. First is a new twist-to-lock mechanism for the rotating diver’s bezel. This comes in the form of an extremely visible ring around the bezel which twists to lock or release the ability to rotate the 60-minute diver’s style rotating timing bezel. When the bezel is unlocked or the crown unscrewed, the user can see orange-colored sections which are an “unsafe” warning.

Another innovation is in the luminant. I don’t believe the luminous material itself is new, but Citizen paints a very generous portion of it on the hands and hour markers of the watch and claims that the Citizen Promaster Eco-Drive Professional Diver 1000m has “2.2 times the afterglow brightness than a conventional paint even after 5 hours.” This is possible, of course, given the traditionally huge hour markers and hands that many Citizen Promaster dive watch have had over the years. From a design perspective, fans of Citizen Promaster marine collection watches can see the familiar look of the watch despite the design evolution of the Citizen Promaster BN7020-09E compared to others that Citizen has made or continues to make.

One new design feature is the “saw blade”-style design of the bezel, which is designed that way in order to be very easily turned even while someone is diving (or otherwise) with thick gloves. Citizen reports that they worked closely with JAMSTEC in Japan, which is a national agency related to diving. This apparently helped them research the design and functionality of the Citizen Promaster Eco-Drive Professional Diver 1000m in real-world environments.

As premium-priced Citizen watch, the BN7020-09E has a lot of quality materials, but it is still sized and designed like a serious dive watch. The Citizen Promaster Eco-Drive Professional Diver 1000m case is a large 52.5mm wide and 21.4mm thick. It will wear smaller, though, given the lugless design and fact that the case will appear to sit a bit high on the wrist. Assuming you are wearing the watch over a diving suit it might not feel as large – though, in all likelihood, most of these watches will spend most of their time on bare wrists. The case is primarily titanium with an AR-coated sapphire crystal over the bezel.

Citizen offers their better titanium for this watch, as the case is made of Super Titanium. That means it is both given the Duratect MRK surface-hardening treatment, along with a DLC-coating for scratch-resistance. Attached to the case is a soft, black polyurethane dive-style strap. Of course, the case is also water-resistant to 1000 meters.

Inside the Citizen BN7020-09E is the Citizen in-house-made caliber J210 Eco-Drive quartz movement. Powered by light, the movement can run for 2.5 years when it is fully charged. The dial offers the time, date, and a power reserve indicator. The movement’s non-removable battery is recharged as light enters through the dial to a photovoltaic cell located underneath it.

Currently, the closest thing to the Citizen Promaster Eco-Drive Professional Diver 1000m in Citizen’s collection sold in the USA is the Citizen Promaster Aqualand Depth Meter (aBlogtoWatch review here) that costs about $950. The Citizen Promaster BN7020-09E is a very different watch with fancier materials, but more than double the price. This is likely a fair price but still a lot given what most consumers are used to paying for Japanese timepieces which are typically appreciated for their value-proposition against European watches. With that said, aBlogtoWatch has probably been part of the reason more people are interested in higher-end Japanese watches.

In Japan, Citizen currently sells a rather similar model that the new BN7020-09E is an upgrade of. The two are very similar though the Professional has a titanium case and more water-resistance. That previous model is the steel-cased, 300m water-resistant Citizen Promaster BN0176-08E and BN0177-05E watches which are priced at around $900 (100,000 yen). At $2,300 USD, the new BN7020-09E Citizen Promaster Eco-Drive Professional Diver 1000m tops the collection and is going to easily be the most interest for serious Japanese tool watch enthusiasts. Availability is said to begin in Summer, 2017.

    It shares lots of evolutionary DNA and similarity with the Titanium Auto Pro 1000m diver’s watch, the NH6930-08F. I’d prefer this modernised version in auto, though, like the original. (Mine has the aftermarket lugs fitted)

  • IG

    Desk divers’ wet dream, The Fat One.

  • They should have made the handset bigger. I can almost read the time.

    • Omegaboy

      A bit bigger and the hands and indices all blend into a lume pie. Don’t know why they put such a honkin’ big tail on the minute hand.

  • SuperStrapper

    Undeniably promaster.

  • Dan Baxter

    Such a tiny face on such a large watch.

  • Shinytoys

    The greatness of the continued aqua land heritage. I want one..

  • Ontos

    It looks like it’s holding its breath

  • cg

    Nice… My 1st edition ProAqualand will not quit and this is a great looking dive device. Though I never do saturation diving I do stops anyway… 125 feet is enough for me for limited bottom time and this watch would be handsome tech overkill that is a very cool tool.

  • frauss

    That’s one frickin hockey puck of a watch! High awesome factor.

  • mtnsicl

    Does it take a proprietary strap? I’m done buying their watches that do. The rubber straps don’t last long before they rip. They are expensive to replace, hard to change and you can’t use a conventional strap on them. Thumbs down for this reason. Otherwise, I like a lot of these Pro Master watches.

    • Peter

      You can get aftermarket lugs for the older models that look totally part of the watch – I’m sure they will become available for this too.

      • mtnsicl

        Yes, I know. And they are very nice. But, it’s getting pretty expensive to buy the watch, the adapters and of course, you have to buy a nice custom strap for it.

  • DanW94

    Obviously a perfect example of function over form, but man that is one fugly watch.

  • Yan Fin

    Just curious, can someone honestly say that he / used a diver at even 500m? Or is personally familiar with someone who did?

  • Pete L

    Blimey that is a whopper. I like big watches but this is even bigger than my Seiko baby tuna(50×15). Must be like wearing an actual tuna can…..

  • Ricardo Cabza

    1000 meters where no light goes, funny, if the average diver went much more below a couple hundred meters, his lights would go out as well.
    All this 1000 meter stuff is nonsense to hook the rubes who are completely ignorant to the realities of diving.
    Since the average recreational diver goes only about 30 ft at best, and a dive that is over 100 ft is considered an “Event” dive only to be done by experienced divers, the majority of this stuff is nonsense, just like helium escape valves.

  • spiceballs

    The advantages of the eco-drive.

  • Sheez Gagoo

    Fascinating. As useless on an average wrist like a Deep Sea or a Plo Prof but still a nice watch for a collection.

  • Lincolnshire Poacher

    I just got my Tuna in the post today! It’s going be my new ‘fun’ watch. I’m still waiting for the after market bracelet I’ve ordered for it. I’m not overly impressed with this Seiko dive strap.

  • The Deplorable Boogur T. Wang

    Kinda like a ricer tuners’ aquatic wet dream.

  • Mark1884

    Too small dial, too big hands.
    My everyday watch is rated to 1524M……. I just dont see what the big deal is?

  • Ulysses31

    The dial is too small and the hands need a viagra or two. The proportions of this range are getting comical.

  • Paul J

    I really love the look of this watch but at that price point I really feel it’s going to be a flop for Citizen, especially when you consider it’s competition in the under $3000.

  • Ricardo Cabza

    For less then $200 you can get this Citizen Eco-Drive diver that will take you as far down as any recreational diver will go.

  • Nikos Exarchopoulos

    Why don’t they paint the disc of the date with luminous paint?

  • Darth Soros

    I like how the seconds hand is exactly halfway between the markers. Top notch stuff.

  • Nano Verge

    I love the over- the-top look and the chubby dials. I bought it and I’m very happy with it. It also gets a lot of attention.

  • andrew

    I own this watch and its an awesome beast, i own 2 other 300m citizen divers, they all look good but this is in a class of its own
