With the M52s shipping this week, hopefully the 300Ms are close to completion. Although it sounded from Bes' previous post about the arrival of movements that the 300M would be ready before the M52. Especially because the 300M didn't need the rotors engraved. The silence on the 300M status has me thinking that Chris and Bes must be working as hard as they can to get them finished and ready for shipping. Let's hope that they're ready soon.
Nessus, I assume the bezel easy spin issue you are referring to was the one with the 500Ms. I remember a post from Chris a while back saying that it had been addressed with the 300Ms. I couldn't locate the post though. To be honest, i've worn my 500M-1 daily for over 1 1/2 years and haven't really had many issues with the bezel moving too easy. Is it easier to move than other divers i've had, yes. But it really hasn't bothered me. It's obviously bothered a lot of people quite a bit, but it hasn't been a big deal for me. I'm tough on my watches too as evidenced by the character (read as scratches) on them. I don't beat them to hell, but they do get worn for regular and work wear.
Chris and Bes, keep up the great work!
