Yacht Masters gaining time

[carl3150]

My first Yacht Master is the mid-size, bought in 2005. Within 2 years, I noticed it was gaining about 2 minutes a week. I took it to Tourneau, the local AD. They tested the watch and told me it was within new watch parameters. It now gains almost 3 minutes a week, and of course, is long out of warranty. I normally wear this watch about 2 months a year. I recently bought full size Yacht Master and after two months of wearing it daily, noticed it was gaining about 2 minutes a week. The AD confirmed it was gaining too much time, and sent it to Rolex in NY. I have not worn it since I got it back. I am not a sedentary person. Any suggestions?

If you haven't worn it since it returned from Rolex NY then you'll have to wear it and report back.

My only thought is that movements can run faster as the mainspring winds down to the last 10 or so hours of power reserve. If you aren't active enough then you could be in that zone of power and causing a slightly faster rate.

Give your watch 50 full turns of the crown to wind the spring, then monitor it for 24 hours. Check the atom clock at the same hour when you start and the following day. It should be roughly in the +/-2 second range if it's just been regulated by Rolex.

This. If it's still gaining minutes per week you have a problem. Most likely magnetism or oil on the hairspring.

If it's running fast, have it regulated - this ain't rocket science...

Sutter's in Chicago is an RSC, I wouldn't take service work to Tourneau.

For the mid-size watch, it never improved, so I reset it every few days. Maybe that's par for a chronometer.

For the full size, I will be returning home next week and will switch watches to see if it is now running correctly.

Ahhh must be a mid size with the cal 2030. Oddly that watch has a magnetic pinion but magnetism can still be in play.

Best to get it checked out and have it timed. Curious to know what the graph looks like. It will tell you a lot.

A 2005 midsize Yacht-master does not have caliber 2035. The 2235 has been in use since 1999 and the 2135 was before that.

Hi R,

What is a magnetic pinion?

The seconds hand is attached to a long axle with pinion, this thing is magnetic so that it moves more smoothly when under the bridge.
Rolex developed this as a solution to having a spring pressing on the pinion like in the 15××.
Instead of the spring there is a small bit of iron above the magnetic pinion to insure smooth movement.

Haha. Its a YM missed that. Also read it as non chronometer. Single tasker.
