Sea dweller 16600 clasp

[Watchgeek5000]

Hi all and thank you for any help on this topic:
As far as an M serial 2008 sea dweller bracelet goes, I cannot get the "perfect" fit. I have come to realization that it is because you can only remove so many links on the 6:00 side. The permenent link attached to the clasp is almost a full size link. I have noticed the clasp on a same time period submariner has a permanent link that is half the size, what I would consider a "half link". I do believe if I swap out the clasp from a sub to my sea dweller I would achieve the perfect balance and fit. My questions are:

1) Has anyone else experienced this?
2) What clasp code would I be looking for (Submariner, but solid end link version only) the older sub hallow end links bracelets have a larger permenent link similar to the sea dweller.
3) Also, what clasp code do I have on sea dweller?

I'm assuming fit wouldn't be a problem, the links seem the same size.

Thanks in advance
