    Hello OFers-
    Starting up on some more research...now into splits (https://alphahands.com/vintage-watch-research/split-seconds-rattrapantes/)

    I'm not too far in, but wanted to share some interesting information (at least to me ::screwloose:: ) on the Breitling 762 split.
    It appears that Breitling produced the 762 not just for themselves, but also provided some quantity to other manufacturers, specifically Grana and Lebois.

    What we see below are:
    Breitling 762 serial 609272 (left)
    Grana 762 serial 609277 (top right)
    Lebois 762 serial 6092xx (bottom right)

    These all have the same steel case, pushers/crown, same caseback stamping style, and Venus 179.

    Rattrapante, or split second, chronographs are a marvelous thing of beauty and complication.

    The one in my collection is a Parmigiani 18k white gold case version, ca. 1999. It has a Venus 185 movement (similar to the 179 but with an added hour counter), these movements date to the 40's and 50's. It seems a small cache of these movements were found in the 90's and made their way to the market via Parmigiani, Ulysse Nardin, Girard Perregaux, and a few other makers. Parmigiani made a series of 10 rattrapantes with different case materials and dial colors. Finished to the typical very high quality standards of Parmigiani. A cool complication, and generally undervalued in today's market.

    Hodinkee has a nice primer on split second chronographs:

    Totally agree that the split second function is awesome. I have the Omega De Ville Coaxial Rattrapante. Definitely a unique movement in the Omega realm. Love it. 01d11cfaa7a619af0406f1d0f70412b7e3ccc7158d.jpg 0105d81d70846ef9817c0f4efda7c58aeaff926786.jpg 01cf1d919021bd219c0f9bf523b263836880603450.jpg

    That seems rather specious reasoning. What firm evidence do you have to prove this claim?

    I would think it was more likely that Breitling, Grana, and Lebois bought the case, pushers, and crown from the same manufacturer.

    Below is a picture of a Venus 190 probably made by Breitling. I contacted Tourneau in the US about it. They told me they didn't have any info to give me however without prompting they did say it might be worth as much as $1000. That made my day!!!

    Re the suggestion on Breitling providing to others...I see that with the Mervos split also (a little more obvious since the movement is double-signed). The Grana movement almost looks like Breitling script might have been removed from the balance cock, I can't tell about the Lebois.
    If someone has any information on those companies all buying independently from the same manufacturer and being OK using the same reference number and serial number that would be interesting to know (I haven't seen that done before, but always have more to learn) - please shoot me a DM.

    @oinkitt were you the buyer for that Tourneau on eBay?

    The purchaser for the Tourneau didn't finalise the sale so I bought the watch off the vender.

    Its been at the watchmakers for the last 2 years waiting for him to make an hour wheel. It appears that someone tried to change the date between 10pm and 2am and destroyed the part. I know I didn't do it, I never correct the dates on my watches.

    The part all the suppliers (4) "suggest" is incorrect. The main plate is actually marked 171.

    This is the part I need.

    This is the part several suppliers have suggested.

    My watchmaker said he will have to machine the lower wheel off the original part, make a new one and fix it back together.

    Hopefully he will get to it this year.
