Accuracy
I’m wondering what you all consider acceptable accuracy for a fifty year old Datejust 1601? It’s losing about ten seconds per 24hr period. Thank you...

Depends when it was last serviced. If it was serviced last year -10s/d isn’t great. If it’s not been serviced in 15 years -10s/d is fantastic.

just sent off a datejust from 1980 that appears to have never been serviced. worn often but never serviced. on wrist it kept good time, but set it down and it was a minute slow the next day. id say -10 isnt bad but it may be time to get it serviced.

My watchmaker says to bring watches in when they start losing time, but 10s/d isn't an emergency.

10 seconds wouldn't bother me.

10s day is pretty standard for a watch 50 years old. They were not expected to be as accurate as modern high-beat movements are.

That's just about what most of my 1960s Rolex run, give or take, when serviced. My vintage 1960s Grand Seikos usually come back from service around +1 or +2 secs per day, but they are all 28,800 or 36,000 BPH.

I’ve just received my 1675 back from RSC, and it’s running just under +3spd. They have it a good clean and swapped out the 8039 hour wheel I’ve been trying to find, and changed the seconds hand, tube, and crown — but nothing more.
My watchmaker replaced a few other wheels and the palate for me, but the rest of it is pretty unchanged since 1971 (when I bought it, there was only one watchmakers scrawl on the case back and the movement was very rough, though it had had a service dial and handset fitted (not at the same time)). I’m chuffed with 3spd for a 50 year old piece worn daily! Sent from my iPhone using Tapatalk

I recently purchased a 1968 DJ 1603 that hadn’t been serviced in 15 years. Had a complete service by my Rolex watchmaker and it keeps time well within COSC standards.

My 1601 I used to have ran at -8 seconds a day consistently. I’d say for a 50 year old watch it wouldn’t bother me.
