ooh cool! It was a Sinn 140a that I was after. I found one, then talked to a few people that had owned them. Turns out there were a few design flaws which I didn't fancy taking on, so I've bumped it off the wish list.
Very interesting movement in the one you posted though, a close relation to the Omega 1040 in my omega 176.007 I guess, with the centre minute chrono hand. Thanks again, I'm tempted ;)
Edit: the Lemania 5012 is a variant of the 5100. Family tree looks like this if you're interested.
remembered you were looking something like this. wrong reference but pretty cool
