Can You Regulate A Watch BY The Overnight Crown Po

[worktolivelife]

Any guys religiously position their watches to regulate them, apparantly crown down to loss time over night and vice versa to gain, im going to give it a try, some "experts" seem to say it makes no difference whilst others swear by it, just interested in some real world opinions/ experiences on what you guys do and your findings

many thanks

Yes you can. I can't remember exactly but I know JJ knows this one.

I do know that putting it on the crown overnight will make it gain. I think on the non-crown side it'll lose.

There's also a diff on crystal down and crystal up.

Wait till JJ comes online.

1. Position: If your watch is slow.

2. Position: If your watch runs fast.


But I never tried it because I don´t care

I’m not sure if you can regulate newer movements, i.e., 30xx, 31xx. I’ve heard watchmakers swear that the resting position does not affect time.

However, I do believe that the older movements 1520, 1570 variants etc. were affected by position as Hannes’ picture illustrates.

Personally I’ve tried on both new and old movements and noticed no difference whatsoever. What I have learned is the more you wear it (e.g., only take off when showering) the more accurate the watch tends to be.

Guess you will just have to experiment and let us know your findings.

thanks'
both my Sea-Dweller and Daytona run at about +3 sec a day which is fine!, but its no hardship to position my watch overnight to get it to run - + 0
if its possible, so i'll give it a try.

Hey Steve,

I'm not sure your going to get a clear cut answer on this. My experience has been that,as Clifton mentioned, I noticed no difference in rate of gain or loss on a newer Rolex based on position. Nor have I noticed newer models needing a "break in period". For example my Sub/Date is +0.5 sec a day and has been from right out of the box. I've worn the watch 24/7 and I've taken the watch off at night. My Dweller is +4 reguardless of position. My GMT II was +15! before regulation and +1.5 after. In all cases I did notice the RATE was consistent day to day.
I have read that a watch will "adapt" to the wearer's habits. I have kinda found that to be the case.
This is in dealing with Rolex.

To muddy the waters slightly,I HAVE found positional variance with my Omega PO. On the wrist it is -2 sec. If I lay the watch crystal down overnite I get my 2 sec back......Go figure.

Certainly nothing to take to the bank,just my experience.

My Explorer II doesn't care which way it "sleeps"....+3/day no matter what I do.

Like Mike said, my PO & other Omegas abide by the rule of dial up to gain time and crown up to lose time.

It's pretty easy to test for yourself Steve and that's the only way you will know for sure.

[JJ]

These are my experiences....

With ROLEX: Crown UP - gain
Crown DOWN - loss.

With PO: Crown UP - loss.
Crown DOWN - gain.

As you can see, the PO reacted diametrically opposite to the Rolex.

You will have to do a bit of experimenting with your own watch and note the results.

Good luck - JJ

hi all
tried it crown down last night and it lost! in fact the bloody thing stopped:(
does anybody know the technical reasoning for crown positioning and how it affects the mechanism

steve
ps i dont think it was the crown positioning that caused it to stop proberly not enough wrist time!
