Question
I am unable to open the back of this watch because I do not see any place on the clasp where i can gain leverage to pry it open. Do you have any advice or tips that i can try with out going to a shop?

Answer
Eric,

There are two ways to enter the back of a watch.

First off, are you sure that one enters this watch from the back and not from the front?

If you are sure, then there are two methods: one is a screw off back and the other is a snap off back.

If you are sure that it is a snap off, then what you need to do is take a single edged razor blade and slip it into the crack, then VERY CAREFULLY start to pry off the back. You'll have to move the razor blade around the circumference of the watch. Once you get started, you should be able to get your case knife in the crack and it will come off very easily.

Kind regards,

Melvin
