In addition to 5065A, I recently acquired 5065J. The bracelet is comfortable to wear despite its strange appearance The one I bought was the 5065J with an additional J bracelet (sold separately at the time), but it looks the same as the original 5065/1J. ...
Or put another way, is the difference in diameter / size between the references entirely attributable to the case? I find the 5066 "easy-going" and immediately attractive. The 5165 also. But I have not experienced the 5065. Good day, chk
