    Working on an ultra thin Patek Philippe pocket watch. After taking this photo (pre-cleaning, but still beautiful!), I noticed that the spokes on the center wheel are numbered. Any explanation for this?

    Not seen this before on any vintage PP I've serviced, so my guess would be someone doing some troubleshooting at one point felt the need to number them. I see all sorts of marks and scratches added to watch movements during servicing - drives me nuts...

    My guess - someone working on the wheel itself numbered them as a reference point. Could be useful if you are trying to find a bent tooth or checking for mesh, out of round, etc.

    Hi Dave,

    This is a very poor practice on any watch, but particularly lamentable on a piece of this quality!

    Regards,

    Graham

    This piece came to me disassembled with a broken mainspring. I wonder if I am also going to have an intermittent stoppage problem to solve once I get it back together...
