Glue is for sniffing .. not watches
If it just "popped off"...I'm afraid some kind of glue will eventually be involved as the retaining ring is just too loose...
NO !!!!!... no glue
What you call BEZEL is in fact the BEZEL ASSEMBLY which is made of 4 parts :
1 - RETAINING RING - that comes on the plexi ... and should fit TIGHT on the plexi
2 - WASHER - that sits loose on the retaining ring
3 - BEZEL - that "pop on" the retaining ring and squeeze the washer
4 - BEZEL INSERT - that "pop on" the bezel (or is fixed with some glue/double sided tape/etc ...)
The pic below shows it all this disassembled ... except the retaining ring which is still on the plexi 'as it should)
So the first thing you should do is to carefully remove the bezel insert from the bezel then push the retaining with your fingers from upside the bezel to pop the bezel off from the retaining ring.
The washer will come loose and you will have the 4 parts separated.
Then you wait some time until me or somebody else continue this explanation ... because now I just have to go to work.
I will try to post later in the morning.
EDIT :
When your there (the 4 parts separated) you should take a pic and post it here.
Then we can help you go further
A clark t39 fits like a glove with no play on mine but no luck on t19.
thanks - i was able to get the bezel assembly apart.
unfortunately the bottom of the crystal cracked when i tried to put it back on (maybe thats why it was loose)?
I'm not 100% certain to understand what you mean so I have 2 questions
QUESTION 1 :
When you write "when i tried to put it back on" do you mean
1 - the plexi (not crystal) on the rehaut of the case ?
2 - the retaining ring on the plexi ?
3 - the complete bezel assembly on the plexi ?
QUESTION 2 :
Did the plexi (not crystal) cracked :
1 - when you tried to put it back on the rehaut of the case ?
2 - when you tried to put the retaining ring on the plexi ?
If the answer is 1 then it means the plexi was too tight on the rehaut so you have to change the model
If the answer is 2 then it means the retaining ring is too tight on the plexi so I wonder how the bezel assembly did popped off at first
I think before ordering a new plexi you should get your callipers and check :
- outer side of the rehaut
- inner side of the retaining ring
and compare to the dimensions of the different "so-called" T39 you can get (Clarck, Sternkreuz, noname, etc ...)
Clarck T39 SHOULD fit your watch but you'd better check the diameters.
- Inner diameter of the plexi should be a little shorter (or exactly the same) than outer diameter of the rehaut
- outer diameter of the plexi should be a little larger than inner diameter of the retaining ring
