Here is the result of some compilation work about Omega and Lemania Timers. It's based on my own collection, some old Omega and Lemania catalogues and of course the Omega "A Journey through time" book from M. Richon. I'd be very happy to get more information... but it's hard to find... let me know...

Most serial numbers on Omega Timers are Lemania serial numbers and very little is know about it as all Lemania archives were lost. Here a graph that can help to date a Lemania serial number:
** crowns changed from round to cylinder around 1962.

Wow, great work. I bookmarked it.
Partially on topic: does anyone know where to find a replacement crystal for my MG6301? I can't find it on ofrei or on cousins.

Great information, thanks. Mine seems to be MG1176 (has calibre 5600). Serial is just over 1 million so late fifties and not forties as I thought.

An excellent summary/collection. Great work.

I can offer a couple of points:
  1. Regarding the 65mm-cased 53.7 rattrapante (beautiful!) movements in chronographs (e.g. the MG1155/201 1130 Rattr and MG6713 1131 Rattr) you show these movements as being 18,000 bph - they are in fact 36,000 bph.
  1. You don’t include the Cal.206 (mentioned in AJTT) - an important, high-quality version, used in observatory competitions etc.
More per PM!
Tom
