    Can anyone tell me the meaning of the arrow mark next to the serial number? Thanks, jjw

    New York Standard Crown Wheel: Removable?

    I looked at close as I can. I can barely see threads, but not with enough clarity to tell which way they go. I turned the screw with as much force as I dare to do in both directions, and it won't budge. Honestly, I don't want to ruin the screw because I won't be able to fix it. Given that I...

    New York Standard Crown Wheel: Removable?

    This post relates to "Lavina 105 (?) Ratchet wheel screw. Left hand?". When trying to remove the crown wheel screw on a NYSTD 1573, I could not budge it, left or right. I removed the keyless works and discovered that the wheel does not need to be removed to get the barrel bridge off. The...

    Instantaneous vs. Average Timing

    Thanks, Al. That sounds like a very meticulous process. I guess there are no shortcuts.

    Instantaneous vs. Average Timing

    Sorry, I think I led the discussion astray by referring to state of wind. My real question is this: Regardless of all the factors which affect it: what is the established method (if there is one) to determine the average rate of a watch over 24 hrs (in s/d) using instantaneous measurements...

    Instantaneous vs. Average Timing

    For example: 100% wind: +20 s/d 0% wind: -10 s/d I would guess at first that this watch would do +5 s/d over a full cycle, but I doubt that the relationship is so linear.

    Instantaneous vs. Average Timing

    Is there a formula to predict the average timing over one winding cycle given the machine measurements (in s/d) at 0% and 100% of full wind? Thanks, jjw

    Service Quality Assessment

    Jerry: definitely, I would like to attend a workshop, but who knows when.

    Service Quality Assessment

    Dewey: amen to that. I don't have 15 years to become a watchmaker, so I'll have to settle for a little education and a deep appreciation for these fine mechanical instruments. My expectations are modest. If I have a problem with a watch that I can't be satisfied with, I'll look you up.

    Service Quality Assessment

    topspy: I am just to the right of novice. I have a half dozen American watches, and I have a timing setup which is partially homemade, but works fairly well as long as I don't have to use it every day; which I don't. My rudimentary methods are what led me to suspect that a watch I sent for...

    Service Quality Assessment

    Thanks, Dewey. I have read with interest your material on watch adjustment. I conclude that, for the user, all these details add up to accuracy and run time, which are the only things an un-equipped user can measure. I agree that the watchmaker should attend to these details. Is it necessary...

    Service Quality Assessment

    I would like to ask of the more experienced members how to objectively assess the quality of routine vintage watch service of the Clean-Lube-Adjust variety (for mechanical watches). As a user, I can think of two parameters: accuracy and run time. If I send a watch in for service, I expect it...

    Fitting movement to case or vice versa?

    Sorry, it was a hunter case, not movement. I never liked it anyway, thus this project, which was good therapy for the lockdown.

    Fitting movement to case or vice versa?

    Wrong button. The finished product: This project would not be the least bit worthwhile to anyone but me, considering the time it took with only hand tools. The 1926 Keystone case is worth more than the movement, but it was doing nothing. But the watch was a gift from my mother, and it...

    Fitting movement to case or vice versa?

    As a beginner, I'm glad to read that this task is not that easy, because it wasn't. I made a 12s Elgin case to hold a Baylor Swiss made movement (Heuer, I think). I made four spacers out of machine screws. I glued them in place, strategically avoiding the stem and balance areas, and ground...

    Hour Wheel Rattle

    I installed a dial washer, as suggested; one more question: Should the washer contact the dial and the hour wheel, so that it must slide on one or the other? If so, do I need to oil this interface at all? I noticed that, when I installed the washer as is, the setting resistance was higher, so...

    Parylene For Melamine Dials?

    I found a company who can do a parylene test run. The cost would be $850. Many dials could be tested in a batch. Does anyone think that enough people would be interested in submitting dials for a test? For example, if 10 people participated, the cost would probably be about $100 each...

    Parylene For Melamine Dials?

    I should explain that parylene is not a process that any of us can do. It's a very expensive factory process. I have some exposure to it because I am in the aerospace electronics business where it is used. Maybe I'll make a friend at a trade show someday; who knows.
