Watch surprisingly runs fine since last weekend (minute hand sweeps as it should, the caliber keeps time) without watchmaker intervention!?!

Is it normal your opinion please?

Hello. I once again need you help to have servicing for one of my Seamaster cal 562 in pretty good shape (pics below). The movement have just been serviced by a professional watchmaker with whom I used to be more lucky. After servicing I wore the watch and noticed it didn't keep time (ie. lost 10-15 minutes). While second hand keep running, minute hand seems stop moving then resumes ticking. All this was seen over several days.
Watch returned to the man behind those works to no avail. In his shop the watch was keeping time (but he was not wearing it on wrist). The symptoms of 'minute stopping while watch still running' are recurring to my disappointment.
Am planning to find locally another watchmaker but before I would like please to know what could be the cause of all this mess? Incompetent watchmaker? Watch parts needed?...
Thank you in advance for sharing your thoughts.

Sounds like the cannon pinion might be loose? Is it just the minute hand not moving, or does the hour hand also not move at all? Sounds like the watchmaker must have just thrown the watch onto a timegrapher and called it a day after the chart flattened out.

Tks @Caliber561 for quick reply. It really hard to tell if hour hand keep moving with the minute one.
Over 6-8 hour period watch movement lost a dozen minutes but still running... Is there a trick to see if mn. and hr hands keep moving along?

Edit to add: Date changes as usual - ie movement don't stop at midnight

It is necessary to tighten the minute tribe (clutch, friction clutch), it has weakened.
I will ask my current watchmaker if he had done this. Thanks

This is a typical symptom of a loose cannon pinion. The one in your watch looks nothing like the one posted in this thread, but in any case it's a very easy fix for any competent watchmaker.

The photo is just for example and understanding where to look for the problem.

Thanks @All. I suspect cannon pinion defect problem because when minute hand works as it should the caliber keeps pretty good time.
