The Lemania Chronograph Calibre 2310 or CH 27 , developed by Albert-Gustave Piguet , is one of the most iconic chronograph movements. credit: @ncwatch on eBay & famille-piguet.ch It was introduced in 1942 in two versions , each featuring either 17-jewel o...
Of these I'd go with the Cornes de Vache or RD, the I like the 5070 movement the most, but it is just too large and the movement is too small for the case.
But there’s something I like better in Omega, RD and PP: the large balance wheel and 2.5Hz frequency instead of 3Hz with the 1142 and 533. Aesthetically, I prefer the Y-shaped (RD, PP, VC) chrono bridge to the U-shaped one (Omega, Breguet) and the Maltese...
It's unfortunate that the finishing quality of the CH 27-20 was unsustainable in the modern era. It's good news that this classic movement continues to be offered today. I will stretch the defintion a bit to say that my favourite implementation is Fleury ...
I wasn’t aware of it. It’s quite nice, even if I’m personally not very fond of the shape of the chrono bridge. I much prefer the traditional U or Y shape. But it’s great to see this modern take. Best, Emmanuel PS: I added the movement of the steel version...
And the caliber 1141 has two great features: a large balance wheel beating at 2.5Hz and a swan-neck regulator. The 1142 doesn’t have them, but it has the Maltese cross column wheel. I personally prefer these traditional looking calibers to the Omega 321. ...
That Maltese Cross column wheel is a nice touch. But this Speedmaster is (relatively) inexpensive, and Omega was also involved in the development of this Lemania 2310 I believe so it has some attractiveness . I'll find time to try one. I wasn't impressed ...
which I prefer. But the 1142, though 3Hz and with a smaller balance wheel, looks a little better for me. And I like the Maltese cross column wheel much more than the capped one of the PP. Best, Emmanuel
the geneva seal -one of the main factors -but not only. the movement/calibre is always first on the list when choosing a watch-then size- how it looks etc
