I hadn't been wearing my beloved 16800 much so decided to have it serviced last month and bring it on holiday. First day at the beach and after a little bit of splashing about with the kids, this happened... I called the watchmaker who told me to unscrew the crown, pull it all the way out, and leave if somewhere warm for 24 hours. I followed his instructions and now the watch has stopped working completely. It's stopped running and if I try to wind it, the crown spins with no resistance at all. I've put the watch away and will bring it back to the watchmaker on Monday as I'm still away from home. Can anyone give me any idea of what has happened and should I trust the watchmaker to work on the watch for a second time. First time, they replaced the gaskets and pressure tested the watch so I'm not sure how it could have failed just a few days after being serviced. Or should I bite the bullet and find someone else to carry out the repairs?
