·- Extra info: They claim that if they were to place the watch in a pressure test, (to test the gaskets) it would pass.
Like on a humid day in the city, or traveling by plane. This drives humid air into the watch by pushing those chronograph buttons
I can’t speak to that specific model but I had that happen a few years back with my Speedmaster Auto (which is even less “waterproof” than a regular Speedy pro case).
Oh yes " Flight qualified by nasa for all manned space missions "
What model of automatic Speedmaster do you have? I don't think any are rated less than 50 m, which is what the Speedmaster Pro models are rated for...
Interesting, have you noticed it after flying with it?
It’s a 3510.50 from 89/90. They didn’t have the screw in case back yet at the time.
