I just came across this thread. I too had this issue with my SMP(ref.126.96.36.199.01.001) after about a year of wear. I only noticed the problem as the crown came to require less than one(1) turn to seat. Omega corrected the issue under warranty. I have more than a few watches, from quite affordable to more costly than the SMP, with more wrist time. This is the first time I have had an issue with the crown threads on any watch. Still love the SMP though. It is my current everyday watch and has been for the last year or so.
