It was introduced in 1942 in two versions, each featuring either 17-jewel or 21-jewel and a swan-neck regulator:
- A two-counter version, CH 27-17P
- A three-counter version CH 27-12P
The three-counter 17-jewel version (as in the photo above) was famously used and personalised by Omega as the Calibre 321.
The two-counter 21-jewel version was famously used and personalised, sometimes without a swan-neck regulator, by Breguet, Patek Philippe, Roger Dubuis and Vacheron Constantin.

Same for me!
But there’s something I like better in Omega, RD and PP: the large balance wheel and 2.5Hz frequency. ...
Don't you own a Cornes de Vache? Seems you've made your choice
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.
I do own a CdV and have made my choice indeed.
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...
Great comparison. My choice is the Fleury FM04
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 ...
Thanks for sharing this modern interpretation of the 2310.
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...
Nice work again, Emmanuel.
I had this before: ...but that Speedmaster looks amazing. ...
This VC 47120 is gorgeous.
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. ...
Thanks for pointing these out.
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 ...
The “Ed White” is certainly attractive.
I’m just personally more attracted to dressier kind of watches. I think being allocated such a piece isn't easy, but not impossible, of course.

Yes, here’s the link, if someone wants to read it.
https://revolutionwatch.com/the-lemania-ch-27-to-the-moon-and-back/ Best, Emmanuel
this young gentleman even had one-ch27-12c version
from the canton where lemania manufacture was based-september 1946-having a well deserved holiday!! ...
The CH 27-70 has a larger balance wheel and lower beat rate (2.5Hz)
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
for me only with- geneva seal- and its improvements it provides over those without.
getting rid of banking pins the biggest.
I'm not sure if I understand what you mean.
Do you mean that you would only collect those bearing the Geneva Seal?
i never thought of it as a theme
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
