How do I know if this will fit my watch?
It fit most of my larger size dive watches... rolex, casio, citizen, and invicta.
Easy. Just ask the guys at Leisure Pro....worked for me. They've been right every time on stuff like this. I put it on Suunto computers. Several of them. They do the job. No bells or whistles needed. Well worth it.
If your computer is wrist watch size it will fit
I have a citizen watch and it fits well with no issues.
Here's a watch I have that it fits
Do a search on this. Go to the wengerna site to see the specs.
Case size (I think this means the watch face diameter) is 39 mm
Lug size (width of the strap where it connects to the watch) is 22mm
