Rare indeed. I have never seen this version before. I like the different style used for the sub dials but I'm not so sure about the 100th minute scale on the bezel. I think I prefer the tachymeter scale.
I've seen the decimal bezel before. Somehow it distracts from the original Tachymetre scale so I've never warmed to it. Subdials on this one are interesting but again, in this respect I'm more given to the traditional looks of the Speedy even if I don't go all the way to embracing the cal 321 as an essential part of my own personal collection. I'd like say a 145.012 but it wouldn't necessarily be at the top of my list. It all depends on what the offer is or indeed what else is on offer. Yes I know, I'm a purist's nightmare :lol::lol::lol:
