    Accuracy measurement, 1953 Explorer 6150

    After three visits getting my watch serviced and then fixing some issues resulting from that I seem to have ended up with a watch that appears to keep very good time. I've now worked out why that is, after a visit to the servicing people this week (just to play with their accuracy measuring machine). It gains around 13s/day Face up, Face down and Crown down but loses about 13s/day with Crown up, which has been the way I've tended to leave it when I'm not wearing it, hence the accuracy has been averaging out...

    BTW does anyone know how good the assorted numbers here are (Amplitude, Beat Error and Lift Angle) or what they mean?

    Here are images for the four orientations plus a view of the measuring machine complete with my watch.

    P.S. See here for a (IMHO) nice pic of my watch... https://forums.watchuseek.com/f23/rol...n-1079543.html

    That is a stunning watch, what bracelet did it come with originally?

    A Rolex metal one with springy links, if that makes sense, so it will expand and contract but looks like any other metal bracelet. I just found it ripped the hairs off my wrist so changed it a very long time ago. (I went looking for it the other day but have no idea where it ended up - I suspect I'll run across it some time after I've lost interest in finding it and am looking for something else...)

    Jason - did you follow the link at the bottom of my original post? (Hmmm, I see I'm wearing the same shirt today as in the picture.) There's also an internal shot (B&W and Colour) in the follow-ups.

    While I didn't get an answer on reading TimeGrapher results here I asked the same question elsewhere and got aimed at this very helpful blog post:
    Why You Should Own A Timegrapher (and how to use it) — WristTimes

    Do note the link at the end of it to the Witschi document is no longer correct, but I tracked its current location down to:

    Sorry for the delay and sorry for the dust on the glass (err, Perspex), it just kept coming back... I repeated the earlier three pics to make this more complete... hope it's what you wanted?

    Wow, what a beauty. Vintage explorer is so classic.

    The aftermarket jubilee seems to be a good match.
