That is interesting. My Sea gull 1963 failed just after Christmas (only had it since May and rarely worn). Winding it up as normal and after the third wind, I felt something catastrophic and the winder felt weird. Looked at the watch face and the hands were bent! The hands moved when trying to wind. I guess the mainspring went and somehow coupled the crown in wind position to time adjust.
I didn't realise this was a known issue. I sent it back to Thomas in Hong Kong so hopefully it will be repaired/replaced. A shame if it's likely to happen again. I really like the look and feel of that movement. And the watch is great too.
