I discovered the same problem with my Costeau last summer. Too late, the letter got into the movement and killed it. Anyway I loved the watch so much that I ordered a new one. But I'm sorry to say, that one had a lot of issues, problems with the inner bezel and the movement was not really tight inside the case. Misaligned dial/bezel. And problems with the chronos, the second hand stops for a few seconds at 10 and 50. I really love that watch, but I wont buy another one with all those issues. Maybe a gen one.....
