New GMT -4 secs

[BetteMidler]

Hey all,

Wanted to get you thoughts. My 3 week old CHNR is consistently running about -4/5sec with daily continuous usage. After reading a bunch about the 3285 movement I’m curious if this is something I should be concerned with at this point or should I wait and see how it shakes out a bit longer.

Normally I’m not OCD but I’m one of the rare breeds nowadays it seems that actually does use my watch as a timekeeping tool.

Bought new from reputable AD.

Tks in advance.

The spec is +2/-2 so I’d have it warrantied if it bothers you. Personally I’d let it be and have it warrantied closer to the end of the 5 year warranty period.

My BNIB 32xx series was also off in a similar way. Took to the AD and they adjusted under warranty. No big deal.

I'd do same, unless you're timing something that doesn't tolerate that type of error and in that case I wouldn't be using mechanical.

The movements are still tested at the COSC TO -4+6 AVERAGE seconds to get the COSC certification to have the word chronometer on the dial. Rolex further tests movement in a controlled environment test to this new -2+2 precision test. Much like the COSC test movement passed test at time of testing. But on the wrist there could be slight variables because of gravity, mainspring power reserve, wearing habits plus many others. This -2+2 spec does not mean it will run every single day for life exactly the same, no mechanical movement made will keep 100% perfect time close yes, but perfect no out of 86400 seconds each day.

Welcome to the forum.

My early 2021 Sub date 41 & 2022 BLRO are running spot on, Hope you get it all sorted out.

.

What are you timing that being off by one minute every 2 weeks matters?

These types of threads blow my mind.

Get it fixed, it would drive me nuts to.

If it's a new watch I'd give it 2-3 months. If it was still outside Rolex spec (+/-2sec per day) I would send it in.

Agree with this. Over 2-3 months it might settle down, if not the RSC can regulate it. Also, I don't know how positional resting affects this movement, but have you tried resting it horizontal, dial-up, at night? My 1675 GMT loses -1 sec during the day but regains it (and some) when I rest it dial-up overnight.

I third this opinion and would add that positional resting does have some affect…albeit not a lot from my real world experience. The -2/+2 rating has already factored this in for the most part..

I don’t think 4s/day would really bother me but then again, my unserviced 31xx movements (4-6 years old) are well within spec so I guess that’s easy for me to say…

[Navin Johnson]

As others have said, I’d give it a month or two of regular wear and if not corrected by then I’d send it back.

I am usually not comfortable sending brand new machines (watches / cars / etc.) to authorized repair centers for them to be fiddled with. I can understand after a few years sending it in for maintenance, but when it is brand new from factory, I don't like to have a watchmaker or what not fiddling around with my new watch unless it is ridiculously off.

When I see others here suggest they sent in their new watch to RSC or AD for regulation, I don't know.

I’m very much in this camp

I’ll add that if the watch is consistent in it’s time keeping it’s even less of a concern.

[BetteMidler]

Appreciate all the responses. I’m going to hold off and see how it does. I prefer not sending it back this new.

I wasn’t sure if the nighttime horizontal resting was myth, but after reading it again now. I’ll continue to do so as I started that routine last night.

Bought new from reputable AD.

Tks in advance.

Before sending it in, try leaving it overnight in different positions. Like on its left side, or right side. See if one of those speeds it up a tad.

As-is you have the worlds most accurate AP, which understandably isn’t good enough for Rolex. They will take care of you if needed.

Let us know how things turn out

[Wcdhtwn]

Give it a few months. And stop micromanaging the time keeping. It's a beautiful mechanical watch. G-Shock, Suunto, Garmin have alternatives...

[vesnyder]

I am certainly no expert, but I have a GMT from 2019 and another from 2021. I went through a break-in period with both of the GMT's (one had to be serviced), but after a while they are keeping excellent time - and certainy within spec. I would give it a couple months before you bring it back. When My CHNR went in for service it took anout 10 weeks.

[sj24k]

always surprised to see that so many people actually keep track of seconds per day. in all my years collecting watches, i don't think i've ever once checked accuracy to that degree. i do remember having one "good" watch being well out of spec, but it was very obvious and way beyond a few seconds per day. anyway, good luck and hope it works out for you...

[DJ2020]

If it's brand new, I would do as others stated. Give it at least a month of continuous wear. If no change I would take to a authorized Rolex dealer and have it checked out. If good then have it regulated. I purchased a Rolex for the accuracy, I expect it to perform as advertised. Otherwise I would have purchased a Invicta.

As others said probably just need to get it regulated

I’m constantly surprised by people not caring a lick if their $10k/$20k/$30k watch doesn’t run to manufacturers specifications. But more and more Rolex is simply jewelry for many folks.

As others have suggested, give it some time and if it’s still running out of spec, have it checked for amplitude issues so if that’s a problem the RSC can “fix” that as well as regulate the movement.

Mechanical interest vs jewelry buyers. Each has very different expectations.

I am one of those. A few seconds more or less don’t bother me.
Own a GPS time signal G-shock and a phone which are far superior instruments for accurate time keeping.

The fine mechanics of any watch are enjoyable but the bling is what does it for me.

[ljupco]

That's a very small margin to be concerned about at this early stage. Let it settle in and try positioning it on its side overnight

[RFC]

Watch movements are not static and time deviations occur depending on use and wearing habits. Buy a Weishi timegrapher from Amazon and test it yourself in five positions. Dial in the right lift angle to get the amplitude. See where that leads before you send it in.

[Shrike]

I wouldn't be risking a case opening for that

[1William]

As stated, give it some time. I would set it and not check or reset it for a week. See how the timing is after that and repeat a few times. In the end I would not send a watch for regulation for a few seconds a day. Too many issues can arise and I would not want to deal with that or being without the watch.

[Sjef1]

Both my latest 3230 and 3235 was running slowly once I acquired them, but just needed to settle in like many others have stated, and are now running within specs +-2 sec.
So give it a few month:)
