Invicta · Pro Diver · Ref 8926OB
The internet’s favourite argument, in steel.
A 40mm automatic diver with a Seiko NH35A-based movement, a coin-edge bezel, 200m water resistance and an exhibition caseback, on a steel bracelet. It is either the best value in watches or the reason people argue about what a watch should cost.

An NH35 for the money
Inside the 8926OB is what Invicta calls caliber IM-A-005, which is a Seiko NH35A. That is the same movement family found in watches costing several times more: 24 jewels, 21,600 vibrations per hour, a stated 41-hour reserve, and both hacking and hand-winding.
It is the reason the argument exists. A Seiko-made automatic, a screw-down crown and a 200m rating for less than most quartz fashion watches is a hard proposition to dismiss, whatever you think of the rest of the watch.
The coin edge
The case is a 40mm steel Submariner-style shape with crown guards, and the bezel is the detail that tells you which watch this is from across a room. It is fluted like the edge of a coin, and it turns one way only, with a luminous pip at 12.
That bezel is what separates the Pro Diver from a plain homage. Some buyers love it and some buy the watch in spite of it. Invicta engraves its logo on the crown and fits an exhibition caseback so you can see the NH35A working.
Where the price shows
The crystal is flat mineral glass, not sapphire, and the case and bracelet finishing are built to a price. The bracelet is an oyster-style steel piece on a fold-over clasp, 20mm at the lugs, and the lume is Invicta’s own Tritnite on the hands and markers.
None of that is hidden. What you are buying is the movement, the rating and the shape. Everything we state here comes from Invicta’s product page and specs.json, not from measuring or wearing a unit ourselves.

FAQ
Yes. It uses an automatic movement based on the Seiko NH35A, which Invicta labels IM-A-005. It winds from wrist motion, can be hand-wound, and hacks.
