116900 3rd time to RSC?

[Kap007]

I purchased my 116900 Sept. 2021. From the moment I put it on the watch was +30 seconds a day. I wear 24/7. After about three months watch was sent to RSC under warranty. When returned watch settled in at +15 seconds a day. I went to Benari Exton and told in house Rolex watchmaker that watch is running fast. She said on timegrapher was -4 seconds a day. I said please slow it down. She obviously sped it up; now +45 seconds a day. Goes back to RSC again. Now after a year a seven months doing +25 seconds a day. I dropped watch off again at Benari Newtown Square. They sent it to the Exton location I was told. From there it may be fixed or possibly have to be sent again to the RSC. I understand the + or - 2 a day is under controlled testing. I just feel the +25 and more is unacceptable. Two questions: Watch does run strong. Is it just a regulation or did I get a lemon? Second question, Anyone on here have dealings with either of the Benari locations mentioned? Thanx everyone.

Something doesn’t seem right. Is it getting magnetized somehow?

It's way out of spec so something is going on. Hopefully the RSC will set it and let it run for a few days to successfully reproduce the issue. If I had a watch which had required that many visits to a service bench since 2021, the first thing I would be doing is selling it when I got it back.

Do you own any other mechanical watches and wear them at the same locations and times as your 116900? Magnetisation is a possibility but your watch should be fairly resistant and all your mechanical watches would be affected to some extent.

[Kap007]

My other watch is a BB 54. It has done the same thing. From the moment I put it on it does +25 seconds a day. I got it in October 2024. Still under warranty. I am wearing it now as the 116900 is being repaired. I will probably send this one in as well.

Seems like it could be magnetized. By chance do you work near any medical equipment or any other devices that could affect the watch?

Something is really weird if both watches run fast only when you wear them, yet the sub was more or less fine on the timegrapher...

Op, the odds of having 2 watches with the same issue is not normal, there is something causing this to happen. A place you visit or something at work or home. I once had an issue at airport security after going through it. My watch was put that machine and I knew it would cause problems later.

I don’t think they are both defective, no way. Magnetism for sure from somewhere.

[502 to Right]

Get a quality demagnetizer.

I’d let them run down to a stop.

Then I’d give them both a full wind (do not wear) and observe how they perform.

[Kap007]

I have done that. Ran both resting with crown up . Power reserve was correct on both. Both gained just a few seconds for the time they ran. They were not touched at all. To answer a previous question, no I am not around anything I'm aware of that would magnetize my watches.

There's your answer. Sounds like the watches aren't the problem.

[Kap007]

The problem is how I wear it then? I wear literally 24/7. Just seems without resting at night it's still gaining too much.

Try this give your watch a full manual wind that's 40 full crown turns clockwise only don't worry you can't over wind it.Then set watch with a reliable time source and wear for 8 hours a day with reasonable wrist activity.Check time once daily with same setting source write down the loss or gain,do this over 7 days then average out the loss or gain over the 7 days rest off wrist flat dial up.

Along the same lines of what I was thinking Peter

First, thanx for everyone's input and help. I did what Padi said. If I understood correctly, I wore my BB 54 for eight hours; rested for sixteen. At the time of my experiment the watch gained 25 seconds a day, every day being worn 24/7. With the rest over the 7 day period the watch gained an average of 14.8 seconds a day. Watch runs strong. Not horrible numbers, but I like to not take it off. Is this a regulation? Thanx again everyone.

[wongga]

I'm not watchmaker, but I would try to demagnetize it first (maybe at a watch maker). If problem persists...then I would think regulation. If regulation doesn't if it, then need to figure out the next issue.

Are you using a laptop? One with strong speakers? My macbook emits pretty significant magnet fields on both sides.

Other common sources are mostly speaker related, or powerful electric motors.
