I'm curious about this one too. I just received my bronze/blue-face San Marten 6105 clone and it's gorgeous!
My only concern is that I can't tell whether the bezel insert is actually bronze or an aluminum insert that's colored to match. Judging from your pic it's actually bronze so I'm in good shape, it's just not oxidizing as quickly as the rest of the case. Did you force the patina or is that all natural?
I'm also encouraged to hear good reviews of these watches. I picked this up on a lark -- I'd wanted a bronze watch for a while and saw this on The Bay. I figured so long as it's running a Seiko movement it'll be as reliable as any other Seiko-powered automatic, and surely the case will have at least decent seals. :D
I do want to hear more thoughts on the S.M. watches, though. So far I'm really shocked at how beautiful it is! In fact, I had a random stranger yell at me out his car window "Hey! That's an awesome watch! What is it?" :D
