Pepsi GMT Noisy Rotor

[Robbyman]

I have just noticed the rotor on my 2018 Pepsi GMT is very noisy. It sounds like a Miyota.
However my Sub, Daytona and BLNR all are quite to the point to you cannot hear them spinning.

I am just wondering if this noise is common with the new movement or the thing needs to go back to Rolex for repair.

Owners could you please let me know how your watch sounds with this movement?

There are many posts of forum about the same subject with the 32 series movements nothing to worry about quite normal, its mainly because they now use ceramic bearings in the winding rotor. They are sealed in a lubricated enclosure and according to Rolex should last a life time. And doubtful if Rotor will need changing like the old sleeve post rotor on the 30 and 31 series movements.

Mine is the same noises than any other Rolex watches that I have owned, but I am not bothered. As Paddi advised its a known characteristic of this movement

im not disagreeing but Bas wrote something about the drawback to this system rotor that needed to be replaced entirely when broke not parted out like the 30 and 31 series

Quite true but extremely doubtful if it will ever fail, the ball-bearing rotors was first introduced with the in-house movement Daytona way back in 2000 not heard of any of them failed.

I have just found this noise on my three year old 126710 , I am sure the noise is new to the watch , I will get it checked .

Robbyman , did you get to the bottom of your noise issues ?

As Padi said earlier in the thread, 12 series watches like yours have an audible rotor (unlike the 11 series before them) and rotor noise is perfectly normal.

It's not normal for Rolex, that's why older silent movements will be desirable in the future. silent buttery winding movement is more important than noisy longer power reserve in my opinion. 48 Hours is more than enough.

Very interesting thank you..

This is something I like about my 31 based Rolex watches. But I can and do live without it, if I like the watch.

Agree about the 48 hour power reserve but as for a almost silent rotor sound being more desirable very doubtful. Now this is main Achilles heel in most all of the Rolex 31 series movements like the cal 3035,Cal 3130,cal 3135 Cal 3155, cal 3185/6 is the rotor shaft bearings, and IMHO its the 31 series movements weakest link the rotor winding sleeve bearings. Now these need proper lubrication and its very critical its done right, if it dries out especially in warm climates you will get severe wear in the bearing jewels, especially if sat on one of these machine winder things 24/7.Looks like to me Rolex has sacrificed a bit in the engineering department for better winding efficiency. IMHO the small diameter winding post don't offer enough support to the rotor weight, but again some go on for decades without service, but many fail for the lack of. Now if your rotor does need replacing and many do, then you can be 100% sure the movement needs a full service as well. Now with new movements like the new 32 series they have ball-bearing rotors. Now these can be quite a bit nosier than the old sleeve rotors in the 31 series, but louder noise is normal in all ball-bearing rotors from all manufactures.

I'm not sure, but I think I recall that it has been the case where the ball bearing has been replaced.
Of course we are not privy to the circumstances around that, but it may have happened under warranty. IIRC
It may have been Bas making reference to it quite some time ago?

I have to confess I deeply appreciate the silent Rotor bearing.
Actually, I have come to regard it as a defining feature of Rolex watches.

If I was happy to have a noisy rotor bearing I could pick any other brand. For that matter, I have to say the new rotor bearing on these watches has reawakened my deeper appreciation for manual winds with the last 2 watches I've bought being manual winds and another one on the horizon.

I know I'm well and truly stuck in the past with my position on this, but I'm very happy with my 2 Rolex watches with an older movement as they'll outlast me anyway. My wife is also most happy with hers to the point she has mentioned that she'd rather have a quartz watch than a noisy rotor
I've never had a broken jewelled bearing despite a serious drop onto concrete so I'll call that a lucky escape and testament to the durability of the movement. It was one of my best watches throughout my ownership of it

Well first look at the Valjoux 7750 range that have powered many many high end brands like Paneria. Now you can actually feel the 7750 winding wobble on the wrist, but thats just one of its quirks but a very very reliable long lasting and accurate movement.

Agree about manual winds myself did have two OPs from the very late 1960s my sons wear them now most days,40 plus years old and still beating strong. Both have had just normal stem tubes service twice if I remember in there life and both still have there original crowns .Automatics in reality made us all lazy press button for this and that. Must have this faster bigger etc but a automatic movement is only a hand wound movement with a automatic mechanism fitted, hand-winds are far simpler and less things to go wrong.

A hand-wound movement "lives" because you actively want it to run , you sort of breathe life into it, and you have to do it on purpose. I think that's an entirely different attitude toward a watch than merely picking it up and find it ticking and working. And knowing that it will continue to do so without additional intervention by yourself, if sat on one of those machine thing so called winders. And IMHO makes you just part of the soul of the watch, and I like having to wind it each day, to keep its heart beating.

When I pick up one of my hand-winds and wind it, the whole process, the act of winding, just seems to have a sense of history and tradition to it. This makes hand-winds special to me. I can imagine my grandfather, and his father, and his father's father performing the same daily ritual, it's a connection to the past horology speaking.

Mine is only from 2 years ago but I don’t hear any noise.

Shake it

[enjoythemusic]

I agree with Padi.

Look, do you want quiet-yet-faster wear, or a 'noisy' longer lifespan? Neither is 'wrong', just that one has a better lifespan... in the long run.

[S.Explorer]

Honestly, I prefer the quiet rotor (and turning the crown forwards to set the time forward). Wouldn't say no to a "Pepsi" at retail price though.

My Pepsi is quiet also. I've owned 2 and both were quiet. DJ41 was really noisy. You could hear it from arms length.

I have to hold the Pepsi up to my ear to hear it and my hearing is fine (tested for OSHA often). I can hear the movement ticking on my wrist on several of my watches.

This is a characteristic of all new movements. Doesn't have anything to do with hearing. If you can't hear the rotor noise when shaking your Pepsi, there is a problem somewhere. Old movement is like shaking a rock, like there's nothing inside. The DJ41 and new GMTs have the same movement inside

Quick follow up , After messaging my Rolex AD they said we have had this before ! Rolex will fix it ,please bring it in and remember to bring the warranty card ,see you soon .

I assume RSC can do something then , obviously I will keep everyone posted on what they do .

Totally normal —-I realize it’s an old thread dig still just wanted to say
