Hi all, hoping I can tap into the knowledge of the Seiko experts on here.

I picked up a nice 1995 7002-7020 150m recently. It’s in excellent condition, and makes a bit of a change to the SKX00# (FWIW, I do have an SKX013, the small one, as well).

It has what I call the knobbly bezel, ie that has parts sticking out proud at the ten minute indices (see pic). This is cool, and makes it really easy to turn, but I would like to add a more conventional bezel.

I did some research, and read that some of these are compatible with an SKX007/9 bezel. Duly ordered from Ali Express, doesn’t fit. Well, I’ve got it on, but it doesn’t move, sort of defeats the object really.

More research leads me to find that some of these are compatible with the 6309 bezel, but some aren’t. Might be the WR rating that differs (apparently the 7002 came in 150m & 200m flavours), might be the model number.

Any help gratefully received!

I acquired a GA2100 (the Casioak). It has a bit of damage to the lug holes, so I can’t use a non OEM strap/ bracelet.

I prefer a bracelet, so I acquired a very different mod case.

I give you the… Casiubmariner!

Quality is quite good, but it is quite a size! Bezel is bidirectional, and non-clicking, quite easy to move, but smooth.
