·I have an Oyster Perpetual Date ref 1500, cal 1570, 19800 bph.
What is the typical accuracy per day? And does accuracy change with age?

·Vintage circa late 1980s? The calibre 1570 is a chronometer. When new, they were usually rated for approximately +2 to -2 seconds variation per day. How long have you had yours, and what is the service history? How accurate is it? What are your expectations? A watch of that vintage usually has a lot of miles on it. I feel it is not reasonable to expect the performance of a new watch from one that is 45 to 50 years old.

·Not quite as old, but this past summer I had my 14000 Air-King from 1999 serviced by Rolex in Dallas. That's a non-COSC cal. 3000. According to my low-cost Chinese timegrapher, its rate error is 0 s/day in five positions and -1 s/day in one. Beat error is 0.0 ms in all positions, and amplitude ranges from 290° to 300°.

·I don't think there is a "typical" accuracy. It depends on the condition and service history of the movement, in addition to the specific caliber. And accuracy isn't measured simply by seconds per day, but variation in different positions, temperatures, and fully vs partially wound.
And obviously, unless your watch was serviced recently, all bets are off. Even if it was serviced, it depends on the quality of work that was done.

·Also depends on how well it’s regulated. 1570 can be quite accurate. All of my 1570s keep great time.

··Oooo subtitles!My Rolex Date 1500 was serviced about 4 years ago and is at I think +5s. Anything from 0-10s is fine by me. Minus is a drag since it is harder to correct of course. Yes you can expect the accuracy to change. Once it desperately needs a service it may run like crap.

·The calibres 1570 and 1575 can work with -2 +2 seconds. Nowadays, the superlative chronometer is just marketing.

·I love to travel with my 1959 Air King and that 1530 loses a fair bit of time.I had it serviced a year ago at rolliworks. These calibers are super accurate but difficult to regulate. It’s a minor annoyance,
