Sector Ocean Master 3253966025 - What Parts Do I Need?

[GalM]

Dear Members, Hello.

 

I own the above watch and was thinking on experiencing with self service for Battery and crystal replacement.

would appreciate your advices on the followings:

 

1. what battery model should I buy for the service?

2. what O-ring size should I purchase for the back?

3. what size of crystal glass should I purchase?

4. is there an O-ring need to be replaced after replacing the glass? if so, what size?

5. what tool do I need in order to open the front bezel for the glass replacement? see attached picture

 

I hope it's ok asking all those question here since I didn't find any info on the web...

 

Thank you all! and merry Christmas.
