SPM Co-Axial Chronograph, the 50th anniversary limited edition, 42mm, mechanical, from 2008.
SPM with a gold bezel & pushers, 38mm, automatic, from the 90's (IIRC it was made in '96)
I get your dilemma, but perhaps because of a slightly trivial reason: I like the date feature for the SPM with a gold bezel. However, hard to beat the 50th anniv edition for all the reasons mentioned above. Personally I'd go for the SPM with a bracelet but that's just because of my own preferences and given that I have other watches on leather straps that I can use for different occasions. I don't own a SPM (deciding between this one and another piece recently and I went for the other piece), but if I had one I'd probably want a bracelet so I can swim with it, etc.
Heh heh yes, Dino944, I suppose this works!
