I was wearing my Sinn 356 UTC on a custom buckskin leather by The StrapSmith - TheStrapSmith - Custom Leather Watch Straps by Rob Montana (I have 5 or 6 of his custom pieces as he does really great work) and I was giving a presentation. To draw attention and give emphasis I clapped my hands loudly and one of the spring bars popped out and my watch fell to the floor. No damage done at all as it was a heavily carpeted floor and the watch was a Sinn after all. This is the second time this has happened and after the first time a year or so ago I swapped the spring bar out and haven't changed the straps since. But now it's happened again for the second time as I just described above.
I have a number of other watches:
- Fortis B-42 Cosmonaut Chronograph Limited Edition Titanium Lemania, Fortis B-42 Cosmonaut Chronograph GMT, and a Fortis B-42 Pilots Professional Chronograph GMT (the first two also on really nice StrapSmith custom pieces and all three have the Fortis style screw in spring bars and tubes so they are not easy to pop out at all given the screw holds them in place),
- an Omega Seamaster 300 Professional Chronograph, a Marathon MSAR, and a Tudor Pelagos LHD all on 'normal' spring bars and official bracelets and all of which are bigger and heavier than my 356 UTC and none of them have ever had a spring bar pop out either.
- even my dad's old gold Rotary has never had this happen and that's an old style small watch with a 35mm face.
I have done the clap thing in a number of presentations while wearing most many of these watches with no ill effects. So I'm a bit worried that this has happened with my Sinn twcie now. Anyone else ever had a spring bar pop out on any of their Sinn watches?
