I wondered why I was having such a devilish time doing the fine adjusting on this a Waltham, on the 25th, and why it was 12 seconds slow this morning. After all, this is to be the subject of a long term test for accuracy. Well, I took another look at it today (26th), and discovered that one of the regulator curb pins was loose! As loose as a grade twoers incisor tooth! So today, it was back to square 1 regarding final adjusting. I am happy with the result, so now the accuracy test starts in earnest.
