Rapid and severe change in accuracy

[diverdoug]

I have a 4 month old DSSD that has been in my safe for about one month with no magnets in close proximity. I wound it at least 40 times and set it and it is loosing about 5 MINUTES per day. Any ideas what could cause a drastic change like this?

[mtgjr]

No telling. These things get pissed off when you don't wear them.

Seriously, though, that sounds very odd.

[MonBK]

Bring it in to RSC and they will tell you.

If your safe is electronic key pad style there are magnets. I would vote magnetism there is an app to check.

The watches are about 2.5 feet from the keypad, so I doubt it (large safe). How can an app check for magnetism?

[SeaDweller50]

Recheck over next 24 hours but every 4 hours take a reading. See if it's a constant error.. if so it'll just need a regulation. If the reading is erratic then there's something wrong with the movement.

There is? Which one?

[sanosan34]

Lepsi watch magnetism app for iPhone works well (on an iPhone 7 at least).

But my understanding is that a magnetized watch causes the hairspring to stick to itself, effecting making it shorter thus making the watch run faster. So if it is running slower than I doubt it is magnetized.

Regulation will not fix -5 minutes a day.
Wear the watch for a week and monitor daily timekeeping.

I thought the bolts on these type of safes were operated by a small electro magnetic geared servo that was only "live" (magnetic) while the bolts were travelling, not all the time.

5 minutes a day on one of these = a trip to the spa if it were mine, I don't think I have ever had one run that far out of spec.

[diverdoug]

My AD also thought being magnetized was the most likely explanation, but is going to send it in to get looked at. I have never had a similar issue, but I am considering buying a demagnetizer.

[HogwldFLTR]

Magnetism is likely; cheap fix if so,

If he thought it was magnetized why wouldn't he just demagnetize it real quick and let you take it back home for a few days to see how it performs before sending it in? They can demagnetize it it a few seconds.

It's magnetized.

They have a centralized shop for their chain of stores BUT I think all watches under warranty get sent directly to Rolex. Perhaps I should have ordered a demagnetizer from Amazon first and tried that. Oh well, it is in their hands now. As a side note, I did not buy this watch from this AD (it was purchased on the other side of the state), but they said they were happy to send it in for me, so either way I appreciate their help. If the watch truly is magnetized, it must have happened immediately before putting it away, because it was stored in the same watch case with the rest of my watches for the past 3 weeks, and was losing time as soon as I took it out and wound it (as near as I can tell). I wound all my other automatics and rechecked them after 24 hours and they are all in spec.

A magnetized watch tend to run fast isn't it? not the opposite happening to OP's watch.

Lets get things perfectly straight when any movement gets magnetised its generally the hairspring that effected making it stick together.This will make the movement speed up and run very very erratic and not slow down.Now since Rolex made a big deal about there hairsprings not effected by magnets its extremely doubtful its magnetised.I would say its either a error on your part or your testing method.

Thanks Peter, you saved me some time.

I am always amazed at the misinformation from some members who should know the answers.

[SeaDweller50]

If the AD said it was probably magnetised who are we to argue. They're the experts.

You are Spot 0n Sir and why ,even Omega claims their METAS certified Si hairsprings are totally immune to any sort of magnetism and their watches will NEVER run slow!

●Is your 4 mth old DSSD pre owned or brand new ?
● Did you at any time drop the watch or was the watch subjected to any sort of violent mechanical shock ?

If your DSSD is running slow ,consider the following reasons :

1#As Mr Peter @padi56 has pointed out , your Method of Testing was erroneous. The DSSD must be checked on a timing machine ,then serviced or repaired. No short cuts !

2#A sudden impact from a fall theorectically could cause the balance spring to " Jump Out "of the regulator pins

3#Faulty loose or slipping cannon pinion is a common cause of a watch acting up all crazy

My Impression : Magnetism has nothing to do with this watch running slow, it could but not in this case !

will also work. Find one with as little casing as possible. Put the compass near the watch, if its magnetized the needle will move from north somewhat.

My AD has a compass made just for this as it was just in a small thin plastic like clear case.

I actually broke down and bought a demagnetizer from a watch tool supply and use it on all my watches.

Having said all that new Rolex have parachrome mainsprings and these do not magnetize, but other parts might.

Parachrom mainspring? That's news to me.

Its a parachrom hairspring in the escapement the mainspring is what powers the watch and thats just plain spring steel.

I have never met a pragmatic man who thinks they are right all the time (and that any view to the contrary is misinformation). there are cases of magnetism slowing down watches. Just google it. What padi described is just the likely affects not the only affects of magnetism.

I fail to see how advocating using an app for detection of magnetism is misinformation.

Error in my testing method?????? It is losing 5 minutes per day. My testing method is that it is losing 5 minutes per day. No exotic testing methods are needed to determine a timing loss greater than 300 seconds per day. Pray tell what type of error on my part would explain that???? I put it in my safe 4 weeks ago, took it out 1 week ago and fully wound it. It subsequently lost 5 minutes per day for 6 days and I took it to the AD.

Electromagnets can magnetize or demagnetize. I used to consult at a facility in dc with electromagnetic bolts on the door. My metro card would never work if i took it thru the doors.

Please let us know how it turns out. Some of the people claiming misinformation on here also said harmonic vibration couldnt hurt a watch iirc. It seems you unfortunately proved them wrong.
