Hi guys - just like the title says. I am not sure what to expect. This piece is bought fully serviced from a competent watchmaker but gains around 30 sec per day - while my other vintage KS pieces (45 7000 & 5625 7000) - also bought from the same watchmaker - are running +/- 5 sec per day.

Am i expecting too much??
Thanks for advice in advance.

Well … 4402 is capable of being regulated to within +/- 5 seconds… that said if it is constantly gaining 30 seconds/day it’s likely to be just an issue of regulation and not due to a malfunction … so up to you if u want it regulated again or live with it …
do check the watch for magnetism ..

I seee. Good to hear that it could probably be fixed by regulating. Perhaps, i will find time to check with my watchmaker to see what he could do about it. Thanks a lot!

In my experience, watchmakers are satisfied with regulating vintage watches to within +/-30s per day. I make a point to ask my local watchmaker who is the best in my area to regulate any vintage watch I take in for service to within 0 and +15s per day and he looks at me funny every time. Old school watchmakers just are not as concerned with precision of watches that are half a century old and I admit they have much more reasonable expectations than I do.

I see…actually I get the same vibe when I talked to my watchmaker. He said he intentionally made it runs fast so that when the oil inside becomes more stiff…it will eventually slow down…but I still don't get it why not make it runs accurately from start lol.

It seems if he has regulated it once, it should be no problem to "dial" it in a bit better. Running +30sec, if worn continuously for a week would be out 3 to 4 min…. But if only worn once in a while for a day, it wouldn't be too bad.

Ha! Yeah, I think that is a common sentiment among watchmakers and in many vintage watch sales listings, +/-30s is often stated as acceptable after a movement overhaul, but 30s is a lot. When I get a watch back that is more than +15s ahead, I will carefully regulate it myself since it is so far away from zero and I can move the regulator arm further without making it run too slow. However, I am always afraid of what my watchmaker will say if and when he eventually opens it up again to see that I have tinkered with it.

Sounds like positional error.

I'm not an expert either, so this might be pointless, but sounds like the watch has large positional error.
Can you ask to check and reblance the balance wheel or the balance wheel assembly ?

I saw positional error improvement by professional watch maker. Check from 26:30

Today i visited my watchmaker to have him regulated for me. So far the watch looks to be keeping good time now. Let me test it a few more days and get back on final result lol. Yes - agree with you 30 sec a day is a lot !

Hi thanks a lot for the insight and video. Will definitely take a look - good learning opp. Anyway, I couldnt bear it so i visited my watchmaker today to have the watch regulated. So far it seems to keep good time now but let me test a few days to see if it remains so lol.

Yes i agree. Thats why it bugged me. + 30 sec means it cannot be an everyday watch without having to adj time every few days. Anyway, i took it to my watchmaker today to have him regulated if for me lol. So far result looks good. Let me wait to see a few more days to see how it goes !

Hi guys - reporting back after getting the watch regulated by my watchmaker - after a few days of normal wearing, the watch has gained 2 seconds in 2 days. Naturally, I am very happy with the result and hope it remains that way for the foreseeable future. Anyway, thank you guys for your advice / comments !!
