1505 gaining 35 min. in 4 hours Did I do this ?

[carwashchris]

I changed my date last night because of the short month. and today I noticed my time was off so I re-set it a couple of times and in the last 4 hours it's gained 35 minutes.

The watch was thoroughly serviced 6/18 and I wear it almost everyday and it's been darn near perfect.

Could I have done something, when I changed the date ? It does feel like it's wound tight ??

Thanks Chris

It is an old watch, magnitism definitely could have effected it

[interestedwatcher]

This isn't watch advice - but when one of my Seikos did that I just had to give it a firm technical tap, and it came good.

I don't know if this is an approved Rolex treatment...

So if true, { Which I never considered } is there a way for me to de-magnetize it or check that it is ?

Thanks Chris

LOL I'll look for my hammer. Thanks Chris

I am no watch expert but if it's running FAST then that likely can only be a few things. Like someone else said it wouldn't hurt to give it a gentle tap to see if it's just "one of those things" but that is usually only something to try when the movement freezes on you. Aside from the idea you somehow magnetized the movement unknowingly (which is not an easy thing to do actually), the only other thing obvious is to make sure it's wound and has enough energy to drive the balance wheel full amplitude. I assume you checked that already so maybe some of the experts on here will have a DIY idea but aside from that it sounds like it's time to bring it in for service my friend

Ok then, a little tap it is I will report back. BTW it actually feels wound too tight, and I rarely wind it.

I reset it 2 hours ago and it's already 45 minutes fast.

Thanks again chris

[carwashchris]

Taped it again on the back side, after 2 hours it was 10 minutes fast. So I tapped it again and as of now 4:21 est it is spot on after 2 hours.

Wow who would have thought, so when I get to the end on June do I dare try to change the date again or let it be ?

Thanks Chris

I’d say you’ve got a slightly sticking balance spring. Chances are it will happen again at some point

Did become stuck when I re set the date or can it just happen out of the blue ?

Thanks chris

"Sounds" as if you possibly have a tangled mainspring. Could this possibly occur from an accidental knocking about? I do not know for sure.

You should at the very least have a competent service professional open it and have a look-see. Watches should not have what you are experiencing, ever.

That's good advice I thought about running it by my service tech tomorrow and see what he thinks it's not a real valuable piece but I still like it


Thanks for everything guys

On my Seiko, it happened when I did a fitness circuit wearing it. So the tap (whilst uncouth) brang it good.

Update, 1 week later still keeping good Time.

What can happen is the balance spring (not the mainspring) can get caught up on itself. It usually gets stuck on the stud where it is pinned. Magnetism, a balance spring that is caught up or a dirty balance spring that causes coils to stick together all create the same problem. Basically, when they stick together or get caught up they shorten the active length of the balance spring. When you shorten it, it gains time, when you lengthen it, it looses time. Tapping it may work, but I suggest taking it to a watchmaker to un-hook it.

Thanks for the explanation of what can happen, I plan on sending it out soon.

Most likely a tangled mainspring. Another possibility is excess lube got onto the spring and it is causing loops to stick together.

A tangled mainspring? Me thinks not...
