2015 116234 sounds grainy while winding

[Maximame]

Good morning gentlemen,

Two days ago, I acquired a beautiful 116234 from a trusted pre-owned dealer. The watch is like new and runs within the COSC specs. According to the seller, it was serviced in February 2024. However, I noticed that the winding sounds terribly grainy. I realized this upon buying it but assumed it was because it was fully wound. Today, however, after it powered down, the issue persists, and I decided to bring it back for a check tomorrow.

I even doubted that the movement inside was an ETA or a clone, but I opened it and confirmed it's all genuine.

I’ve had many 3135s and know how the winding is supposed to sound, but mostly from the 90s. This is my first Rolex with a "late" 3135, so I might not be familiar with the feeling. Any advice would be welcome.

I am also enclosing a quick video.

Many thanks,

M

members, be careful downloading this 1.72 MB zip file from an unknown member

OP: you should delete your attachment, and upload the video to youtube...if that attachment even is a video, which i doubt with that filesize.

The attachment is a 3 seconds video of me winding the watch (and yes, it's only 1.7m, I don't see tbe problem). The system would not let me put the YouTube video as I have not reached 10 posts yet.

Why would I create such a story with detailed information on the movements, and be a scammer?

I understand that nowadays one should not trust the other, but prejudice is also bad

Thanks for help anyway.

Every watch has its own characteristics. I don't understand what "sounds gritty" even means, but an unwound watch will be noticeably smoother than one more fully wound.

The tightness/lube of stem seals, grease in the mainspring barrel, lube of the winding gears and reversers, and on, all have a role in the feel. If you are truly concerned, then take it in to a good watchmaker for an expert opinion.

I haven't watched the video, so I will go off the usual suspect when I hear "grainy," assuming the watch is freshly serviced. I would go straight to the reversing wheels in the automatic module. Likely they are either magnetized or their lubrication is not ideal.

If this came into my shop, the first course of action would be to demagnetize the piece. If that does not solve the issue, I would remove the automatic and check the winding with the automatic detached. If it feels fine, I would reservice the automatic. If it feels grainy while the automatic is detached, I would have to perform more troubleshooting. Possibly the wig-wag, or another component of the winding / setting train.
