I was going to Everest base camp last week when about 4100m the crystal on my PRS 25 jettisoned itself from the case.
I was standing completely still at the time so was able to pick up the crystal and push it back into place for safe keeping.

Now were back in Kathmandu I've a bit of time to think about what happened and what to do next.

Guess the pressure in the case was higher than atmosphere and the weak point was the crystal?

Should it have happened with this watch, especially given the name/heritage?

Given I put the crystal back in and put it in my bag will it be in place firmly given the lower pressure in the case than sea level atmosphere?

I'd like to get it "fixed" properly, mostly to get the dust under the crystal out of there.. What would that entail and who could do it?

I'd also like to get the rotor quietened (lubricated) at the same time as it's almost sounded a bid "dry".

Watch is probably about 4 years old and has very little wrist time, mostly due to the horrific noise of the rotor and it being a bit big for my taste.

Thoughts welcome.
