Just got this today and having removed the caseback found no gaskets
not an expert but was hoping to find out the following;
the recess in the back(pic 2) measures 30mm is this the size required or smaller and stretch it?
is ther one also to fit on the case back?
flat or round?
Bulova supplied or generic ok?

case back has the following markings

MLB
386-3
M8

not looking to go swimming with it just want a little protection against sweat and condensation

crappy photos below
I await your advise

thanks
Guy

I'll comment until the experts get here.
M8 = 1968
MLB = ? I would guess somebody's initials.
386-3 = ? not enough digits
I would say that any 30mm gasket that will fit will work for what you want it to do.
Please be aware that it is my understanding that the snorkel requires a specific purpose made crystal to be as waterproof as it is supposed to be.

here's a shot of the caseback
I think all the markings are factory
but this is only my opinion

Now we need a shot of the outside of the case back.

Will be looking forward to it.
