I’ve been wearing my Invicta Pro Diver 8926OB for several weeks now, and I can’t be happier. It has a nice heft to it (155g), grasps my wrist comfortably, and seems to be very sturdy. The watch isn’t too large to take all the attention, neither is it too small to look awkward on a man’s wrist. They all have automatic movement, which means they don’t require battery power to run. Instead, the movement (engine inside) is powered by the kinetic motion of your wrist when you casually move around. This means that the watch will stop if you stop wearing it for about 40 hours. On the other hand it produces a smooth weeping of the seconds hand that’s found in most luxury watches. 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 8926 and 8926OB use a Seiko Instruments Inc (SII) Caliber NH35A. This is a very reliable movement that’s found in many watch brands. 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. You might be used to a battery-powered (“ quartz movement”) watch, but the fact is that most expensive and luxury watches use an automatic movement. 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 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. 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. 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. 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. Great review, in my opinion: balanced, and tells you what you need to know to make your own mind up. I’ve bought one of these watches (Invicta 8926OB Pro Diver with the non-branded NH35A movement), because I’m rather anti-snobbish when it comes to brands (not all the time, I admit, but then I’m only human), and I suspected that one could get very acceptable quality for a fraction of the price of mid-to-high-end brands. Indeed, that is the case, in my experience (n=1). Initial readings from my timegrapher are as follows (fully-wound, of course):

The 8926, 8926OB, 9937, and 9937OB are very similar watches. Kudos to you for trying to get a straight answer about it. 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. The two most significant cons I faced were the almost non-existent luminosity and the rattling noise of the bracelet. 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? The 9937 and 9937OB use a Sellita SW200. This is also a reliable movement that’s found in many watches.

Replace a band

OB” stands for “original bezel,” which is the coin-edge (Rolex-Style) bezel, so the 8926OB and 9937OB would have those.
