    That's pretty much the list Chuck Maddox and I got to back in 2005. I'm not aware of any other variants of the Lemania 5100.

    I have been more than inspired by the work you put down at the time, but have also been unable to find any more variants.:thumbsup:

    Some info will soon be published on the topic, so I am trying to ensure I got all covered.
    All counted my list of Lemania caliber designations (including Nouvelle Lemania) now closes in on 140.
    A productive "little" company it was.....

    Yes, the 5270 present in the Chronosport Chronosail. 28800, Hand Winding, Sweep seconds and minutes, date (at 6) and (although not a movement complication) this watch also used a Doppelzeiger to give 10 minute countdown as well as a traditional chrono minute indication.
    I am not sure there was a specifica designation for it, but Heuer also used a 21,600 bph version of the 5100/5012 in their 500 series watches, a version that did have the 24-hr scale at 12 that the 5012 more usually omits. The model they used it on was called the 510.500/12 -

    Completely forgot about that one. I even have one myself...
    It is in my full list of 51xx movements!

    Mine:

    Found an old ad for a 510.500/12 Heuer with movement shot.

    Seems 5012 designation only.

    Good catch about the 5270, Dave! :thumbsup:

    Having owned a 510.501/12 myself, I can testify that it was a standard Lemania 5012 inside.

    Hi,
    This thread lead me to buying an Eberhard chronograph as mentioned here earlier. I received it yesterday and I would like to revise it.

    I'm still looking for a parts list, exploded view, repair manual, quartz test procedures... anything that could be of help with a revision. So if anybody could give me a tip where I could source any documentation ::psy::

    In my search for any documentation I stumbled upon an interesting item on sale on eBay.(search for "Omega Speedmaster Prototyp Dial - Parts") It is an Omega dial that clearly is meant for Lemania cal. 181 and it has the word 'Speedmaster' on it. It makes the Omega prototype mystery even more exciting.

    Not optimal but the patent papers contain at least some info:
