6139 Bezel Removal

[earthphase]

Hi guys....

Anybody got a video showing me how to do this?

Which model of 6139?

The bezels are different between models.

Pogue. Sorry.

The bezel has a groove machined in it (here's the underside)




look for this - it's usually at either 12pm or 11pm (but it could be anywhere around the bezel depending on what's happened to it in the past).

Then you need a case knife (or something similar / suitable).

You just push this into the groove - keep the blade flat so you don't mark the underside of the bezel or the case. If the groove is at 12pm then there is little case to mark. If its at 11pm then be careful, you can mark the case. Putting tape on the case will prevent damage.

The bezel will come off as you drive the case knife inwards.

This is what you'll have




it will probably be dirtier!!

To re-fit the bezel you need a press. Don't fit the bezel with the caseback on - you run the risk of crushing the caseback (unless you use a concave die to hold the case/caseback).

Don't be worried about cracking the crystal. In my experience the bezel will self centre (over the glass). You'll hear a snap/crack as the bezel seats home, but it won't be any damage.

The tricky part is getting the bezel on so the tachy mark is at exactly 12pm. It sometimes takes a couple of goes. So you'll get familiar with taking the bezel off!!

Good luck.

Sometimes they are strongly bonded with 40 years of someone else's filth. I never really got along with standard case knives, so I've developed some different strategies.

I usually use these two tools to get the things off.

1. Razor blade to get it started and if it's really bad I run it around the edge a bit just to dislodge the filth glue. You will cut yourself at least once. I hold the case in a cloth so if I slip I retain my full set of fingers. 



2. My trusty Victorinox. I usually use the small blade because it's good for pretty much nothing else. If I need more leverage, I use the can opener blade once a bit of a gap has started.

Maybe I should introduce you to a cousin to your victorinox mega tool.
