The 9937 and 9937OB use a Sellita SW200. This is also a reliable movement that’s found in many watches. From my own experience, I can say that the Invicta 8926OB is definitely worth purchasing, especially considering the unbelievable price that gets you a Submariner lookalike with an NH35 automatic caliber. For the price, the watch offers more than you can wish for. And although I have worn it for only a couple of weeks, the whole construction and the prestige of the caliber suggests a long lifetime. The non-OB models have a scalloped bezel (Omega Seamaster-Style), so that would be the 8926 and 9937. 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.

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. Are there better watches - probably. Better values - I think not. At 40mm it's unisex, it's stainless and waterproof, replaceable bezel insert, Flame Fusion crystal - no - but it's tough and scratch and shatter resistant, the dial face is very well printed with tastefully shaped markers reminiscent of much more expensive watches. The hands are tastefully done to compliment the markers and style of the aquatic big name big brother to it's infamous design. The Japanese movt is a well proven movement with a pretty high bps count that leaves only the slightest detection of the second hand "jitters". At the price point these watches can be had for - you can't hardly go wrong. Since I have been using 9937's and 8926's for many years the only degradation in production quality that is of slight n otice is the band/bracelet is getting "lighter." Clasp works well, as do the lug end pieces of the bracelet. I own a ridiculously large number of these watches with every known variation of the 8926 Model series, A, C, OB (several) and the plain ole 8926 with and without cyclops - they have required very little attention from my watchmaker over the years. This the most recent "OB" is yet another cycle in the 8926 as it does NOT have "Japan Movt" stamped at 6 - another plus for my collection. Read full review 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. 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?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.

The Invicta Pro Diver’s case is a tug-of-war of extremes for me. There are aspects I find incredible about it but there is also one thing that makes my blood boil. The dial is covered with a mineral crystal, which is pretty much the standard in affordable watches. Hoping to get a sapphire instead of a mineral would have been too much to ask for the price point. Another problem that caught my eye, although a slight one, is the gap between the three links when bending the bracelet. What causes it is the pinhole in the center link that seems to be too wide. The gap is also the very reason contributing to the rattling noise of the bracelet. Sizing. The case has a diameter of 40mm whilst the width of the watch band is 20mm. 40mm is just slightly larger than your standard men’s watch at 38mm. It’s not a bad thing in itself that it doesn’t turn easily because a dive watch can’t have an easy-to-turn bezel. Besides, most of us won’t be using it frequently anyway, and it serves more of a visual purpose rather than practical. However, I would’ve preferred a somewhat easier operation of the bezel.I’ve been wearing it inside for my daily routine, as well as outside while shoveling snow and taking a walk. The watch is noticeable on a wrist when you want to but stays unnoticeable when you don’t think about it. When someone is thinking about buying the watch, I think the question is more related to how those with informed horology opinions feel about it. I see threads on forums all the time asking if this watch is any good and the comments are usually all over the place and honestly unhelpful. The worst comment of all is someone telling the poster that for the same money they could get a Seiko SNK or something such. That’s the worst response ever – this isn’t a decision based on value first. The hunt for a 40mm Sub case is a personal decision based on looks– you’re interested in the Invicta Pro Diver because of how it looks. It has a BPH of 21,600 which means that it has a smooth sweep of the second hand at 6 beats per second. The power reserve is a standard 41 hours.
