The 9937 and 9937OB use a Sellita SW200. This is also a reliable movement that’s found in many watches. In the introduction, I asked three questions regarding the Invicta Pro Diver – is it good enough, will it last long enough, and is it worth buying?

Despite its high water resistance level, the watch isn’t ISO-certified for professional diving. It means it hasn’t been tested in real conditions in the sea but in still water in the laboratory. It may withstand the conditions you’ll face with recreational diving (up to 100ft), but I wouldn’t bet on that. The NH35 movement is made by Seiko Instruments, which also makes the Seiko watches. They’re a Japanese company making some of the highest-quality watches and movements on the planet. Sellita SW200 If you have a preference for one or the other, that should be your main decision-making reason. Movement: NH35A VS SW200All in all, my wearing experience couldn’t have been better as the Invicta Pro Diver makes it an excellent everyday wearable. The dial is made of a mineral glass which protects the watches chronograph display. The display also features a date indicator with a magnified window. The watch also features luminescent hands which will make it easier to read in the dark. The two most significant cons I faced were the almost non-existent luminosity and the rattling noise of the bracelet.

if joy per dollar spent were a factor, these are top watches. they shouldn’t be judged by all the other cr*p Invicta puts out. judged on their own, if you want a great spec, classic style sub that looks good (yes, except for the engraved ‘invicta’ on the side), then this is totally worth it.I did the first image right after strong light exposure, the other one approximately an hour later, and the third one three hours later. The results were disappointing, to say the least. I would have hoped to get a much better luminosity from a diver than from a casual chronograph. Finally, there’s also the Invicta 8926, which comes with a scalloped bezel instead of the coin-edge version. All the other visual and physical features are identical to the 8926OB. The Invicta Pro Diver also comes 200m (660ft) water-resistant. I haven’t tried it out in the water yet, but swimming or snorkeling shouldn’t be a problem with this watch. However, taking it deep down for diving might not be the best of decisions. The first thing you’ll notice is the sweeping second’s hand that makes six steps in a second and gives a nice gliding motion. Those of you who have worn only quartz watches will definitely find the sweeping motion the best part of an automatic timepiece. Sellita is a Swiss movement manufacturer, so some people place a premium on that, and this may be why the 9937 models can’t be found for a cheap price anymore.
