3120 running crazy fast

[chiko323]

So today I got my 15300 in the mail and I have to say, its absolutely beautiful. Its my favorite watch I have ever owned. Unfortunately, im having a strange issue with it. I wore it all day and it seemed to be keeping very good time. Then later this evening I put it in its box and when I took it out an hour later it was running four minutes fast! I thought maybe it was a fluke so I reset the time and an hour and a half later it was four minutes fast again. I reset it and I put it on and its already two minutes fast after 45 minutes. I didnt know it was possible for a watch to be running so fast. Is it possible it is just magnetized or does it definitely need immediate service? Thanks in advance!

Mine was running fast also. Now its in Clearwater undergoing adjustments.

It's my understanding this is an unfortunate symptom of the movement. But I also understand Clearwater is the best in the biz and will fix it and it'll come back perfect!

Another 4 weeks for me to find out how it turns out

had the same issue: just magnetized

I dont think its possible with the AP's case. I think it has something to do with the motion of the movemenent (rebanking/banking)

Hi, since we're all on 3120 movement, can I check with u guys on something? Every once a month, I would adjust the date n time for all my watches. While doing that, I notice that once I complete the adjustment, when I press in the crown, the minute hand jump off the mark. (Eg if I set at time 1:30, after pressing in the crown, it jump to between 1:30 & 1:31 mark). All my other watches, IWC, Rolex, Sinn does not behave like that. It happens to both my steel & forged Carbon Divers. Anyone else notice that as well? Is there anything wrong with my watch or that's the norm for 3120 movement.

The OP's 15300 isn't in an antimagnetic case, it's open back and can be magnetized.

Oh right. Sorry for the mix up

[JorgeCCW]

If it has the same as mine, all they need to do is to change the main spring to avoid rebanking.
Good Luck !!

Yes mine jumps further (10:30-10:35ish) when pushing the crown in.
I think its the winding mechanism. I dont know, i am just guessing.

[chiko323]

So I put it in the box all.night and eight hours later the time is still spot on. Hoping maybe yesterday was just a fluke!

Mine was spot on or +1 when left on the box, as soon as I put in the wrist is when goes fast. I really hope that yours it's just a fluke.

@kadhytia

I got mine demagnetized and it ran accurate

@des23

same problem; but I found out that I could set the time more correct, when I push in the crown at first at date-level and later complete

Good to know that it is not something major.

[improviz]

Think the crown push/time jump stems (pun intended) from the ease of the time setting; it takes very little effort to set hands compared to most automatics, which IMO makes it a bit more susceptible to movement when pushed in. Try putting thumb on opposite side and gently pinch it in. Also if you observe it moving in the same direction when you close it, set it a bit before where it wants to jump before pushing it in.

Does anyone know the cost to repair outside the warranty through clear water for this issue?

How far out? Since this is a known issue, I would think that they'd be willing to work with you on it; RSC recently fixed my GMT IIc which stopped dead (likely from a known issue, though of course they tell you squat about cause) and had been out of warranty for some time for free, worth a shot! I'd call Clearwater and discuss.

Mine was six months out and they are willing to do it under warranty. Also on top of that they give additional 2 years warranty.

They wont tell you on the phone. Its decided after you send in the watch then theyll tell you if its possible for them to service it under warranty even after deadline. And i assume its based on a case by case basis.

Glad they came through for you!

Same with RSC, they looked it over first and said it was a free overhaul. Difference is I live near one so no shipping hassles to deal with

[chiko323]

Just another quick update. I wore the watch all day and its been accurate over the last 24 hours. Approximately +8 seconds. So not great, but certainly liveable. I'm getting more and more optimistic that it was just a fluke :) maybe acting weird due to going through the mail

That's what I did. But just don't understand the logic of it. All my other automatic watches don't have this issue...

A few of mine do, and they, like the AP, have hands that require virtually no effort to turn, while the ones that don't do it as much (none are perfect in this regard, save for the Daytona) are more heavily damped.

Yes I could notice the difference with the Daytona

[improviz]

Daytona is amazing in that regard. Other Rolexes always have minute hand alignment issues (i.e. I align perfectly, click crown in and it's still aligned, but when second hand crosses 12 at next minute, the hour hand isn't aligned with the tick or it's ok there but 30 min. later on other side of dial it's off), Daytona has none of that, click it and it's a lock, no drift on that sucker.

Used to bug me a bit with the others, but then I realized that I'm just glancing at it for approximate time anyway. But I do marvel at the Daytona's perfection in that regard, that's a great movement.

My 26120ST was running so fast, too.
Not 3120 movement, but 2329/2846 JLC based one.
Now in AP service. They said the spring was too strong. I didn't know what's meaning. Anyway 7 weeks waiting oops.

Did they used the term rebanking/banking?

Sorry, they explained in Japanese.
"furi-atari" means somewhat of "excessive balance motion" I think.
Is it "rebanking" or "banking"?

[Kadhytia]

From Merriam Webster
"re·banking
Etymology: re- + banking, from gerund of 2bank
: a malfunction in a watch caused by excessive balance motion that makes the roller jewel strike outside the fork horns and renders the escapement inoperative —distinguished from overbanking"
