    Hello all,
    I found a very rare and interesting Longines pocket watch I wanted to share.
    Because I tried hard before being able to identify the movement, as a game I propose you to guess which one it is !

    That could very well be a Longines 8-day watch. Don’t ask me about calibre. If I’m right, is there a prize? :)

    Yes, an 8-day. very close to the cal. 19.41, but not identical.

    As @Tony C. wrote, it looks like a relative of cal. 19.41 but possibly smaller?

    Yes it is an 8 days power reserve movement !!
    Is a prize of honor enough ?

    Indeed, it is linked with the cal. 19.41 development, and has a same size (it is also a cal 19’´´) !

    Looks very simular to the 19.41 apart from the winding gears:) Interesting piece!

    A clue: you won’t find this caliber in Patrick Linder bible dedicated to the Longines calibers !

    To me, the ratchet wheel looks larger on this movement than on the cal. 19.41. I wonder if the barrel is larger too. Also, there is a more conventional gear train (no additional wheel as on cal. 19.41) and no "reversing" wheel between the ratchet wheel and crown wheel. I suppose that there is still a power reserve, given the wheel engaged with the crown wheel. The serial number suggests an invoice date that is not far from the cal. 19.41's introduction in 1914, as per Linder's book.

    Edit: I think that the barrel probably is larger, given the eccentric position of the "center" wheel.

    Are you sure it's not in one of the footnotes? ;)
    Some calibers are not in the big table, while being mentioned in footnotes...:taunt:

    This is the (first) answer sent by Longines by email :

    5D464E78-567E-43A5-8302-DF768C94A840.jpeg

    So it is a cal 19.8 !!

    What is even more interesting is the second message from Longines with additional information :

    EC3C985E-9569-42BD-980C-5C06435AC094.jpeg

    The first 8 days movement from Longines was this cal. 19.8 whose production started in July 1914. For some reasons, maybe the fact that they were not fully satisfied by the result of this first caliber, they stopped its production in July 1915 and started to produce the cal. 19.41. So history of the cal. 19.8 is included in the development of the cal 19.41 !
