@ glenn: stilty is a veteran member here who made spacers for franken builds a while back. they were machined to use the 2892 in place of a 3135 with a gen date wheel as an overlay.
these spacers are no longer made, and unfortunately there are no other reasonably priced options I was able to find. I was extremely fortunate to be able to source one.
I would keep and eye on the TC case. he commented that it is designed to take an eta, and the 3135. that would take the spacer out of the equation.
@6now, you can put as many gen parts on it as you can afford. my opinion, you have to get a gen insert as a minimum. the one that comes with it sucks! the dial that comes with the kit is not 100% either, so a gen dial, if you can find one, is a good idea too.
the bracelet is not a bad bracelet, there are just too many items that make it too far from the gen. The clasp is very nice, and useable. you need to mod the holes for the divers extension if you are going to use a gen extension and pin (the one with the indent on the end). the holes are not large enough to take the gen pin.
This pin is a pet peeve of mine, thats why I do it. you can get a gen extension and pin off the bay, just buy a sea dweller kit, it should come with all the pieces you need, and a screwdriver!
