SKX 031 not 037, AKA 7S26-0040 which where cheaper and slightly smaller then the SKX 007. Oddly while cheaper they have a better dial and bezel then the 007/009. While 40mm not 42 like its bigger brother they both share 22mm straps. There is also a Pepsi SKX 033 out there.

In case you are not aware of how the dial is better... These have applied hour markers vs printed. The bezel is much better looking and made then the 007 bezel which if you own one know it does not quite match the rest of the watch. Over all these share the same movement as the 007/009 in a Rolex Sub like case size, but appear much higher quality in hand due to the upmarket differences on the originally cheaper watch.
KIller pieces also called the Seiko Submariner.
Dibs on the one on the right. And I want to mod it with a 007 second hand... Or buy a 31 dial and mod a 007 (argh can't dial feet and datewheel are off...)
