    An update is owed to those here that guided me in having this watch restored. I acquired this Vacheron & Constantin as a non-runner but with the provenance of having achieved Honourable Mention at the 1910 Geneva trials. Although V&C named the model line "Chronometre" Royal, the vast majority of over 10,000 pieces manufactured from 1907 into the 1940s were not certified as chronometers. This one is only the second I've come across.

    The watch required a new balance staff and jewel, rebuilt center wheel, general clean-up of surface corrosion, full service, and replacement of incorrect crown and crystal. It now runs like a champ, losing under one second over 24 hours. Thanks all :)

    Do you know who originally adjusted it?

    It was Batafolier according to the bulletin from Observatoire de Geneve.

    Ooops, that should be Batifolier :oops:

    The Crausaz balance is indistinguishable from Guillaume's. The sister movement to this piece, 344762, took 1st Place at Kew and 5th at Geneva in 1909. Between 1909 and 1910 there were several V&C pieces at competition from the 34476x series.
