Pepsi running slowwwww

[jeffgo888]

I normally have it on the winder and dont wear it for days
and checked today and it was 4 mins off...weird
Not sure why

[jmcamacho007]

Might be time for a service. What year is the watch?

I don't know Jeff, sounds like a small sample size for anyone to take an educated guess

[jeffgo888]

sorry
its been like this for weeks now...and I got this BNIB, year 2018

Four minutes per day? Have you tried winding it manually 40 plus turns of the crown?

Hi Stan
yes, but its also been on the winder all this time

[dnd2984]

Is it 4 mins per day, or is it off 4 mins since last time you put it on winder? If so when was the last time you checked?

[ArtNouveau]

First off I don’t use winders so that proves nothing to me. Secondly, my BLRO also attained in December 2018 started slowing down at around two years. A free trip to the RSC then, it’s been spot on since.
I would wind it fully and wear for a few days before coming to any conclusions.

Wind it 20 times in the morning.

Set the time according to time.is

Wear the watch the full day.

12 hours later, check how accurate it is comparing it to time.is

Let us know.

Good points

[jeffgo888]

thanks everyone

I did a full wind right now, and will wear it rest of day thanks

If still within warranty, send it in. Even if not, send for service.

C’mon Jeff, “Pepsi” not nearly enough info to date it??

It could be 69 years old and in need of a service.

Unlikely as it was a 2018 purchase - unless it was bought in late December.

[Andad]

My sincere apologies Jeff.

Obviously I am more than 69 years old and missed that post.

I should have my eyes tested again.

That won't be a full wind. I'd say 40 rather than 20.

If I'm checking accuracy over just a 12h period I'd rather start at a half-wounded watch, would in theory give you a better indication if something is wrong.

In theory the better test would be a full wind till the clutch sets in and then put down it in different positions over the next 3 days to see when the reserve runs out and how accurate it is keeping time over that period.

A 12h test is however a great quick indicator.

Don't know why they call them watch winders sure they will keep them ticking but normally only top up to what ever mainspring power reserve had to start with.So if you have to use one of these winder things always best to fully manual wind before putting on machine.But like others have said give your watch a full manual wind thats 40 plus crown turns clockwise only.Then wear as normal for 8 hours plus a day.Do this for around 3 days check time once daily with any reliable time source.Then average loss or gain over those 3 days if well out of spec it needs regulation or service.

There is no clutch all that happens when mainspring is fully wound it just slips in the spring barrel just like it would do on the wrist wearing if very active.

Sound advice I didn’t know that cheers

It's however false.

Maybe some cheap Chinese winders, that were made by someone without knowledge of an automatic movement, programmed the winder to rotate too little to give additional power reserve to the watch, but most winders absolutely power up the power reserve continuedly.

From a business perspective, imagine the amount of returns a business would have if a winder didn't actually wind up a watch. It would also be impossible to assure any watch you put on would be kept at a certain reserve.

Add to that, most winders have different settings for how frequently the watch should wind, as well as each watch being different in it's efficiency of a single rotor spin.

My thought before even opening the thread.
Good advice already given. Good luck Jeff!

We don't talk about things like that around these parts anymore.

Well around 12 months ago myself and my watchmaker friend done a experiment on two watch winders one was a obita other wolf.Two watches were used both subs 16610 and same age they were fully stopped before putting on machines.They were both set to the recommended daily turns and run for approx 48 hours on machine.Both were taken off machine and left to run flat on bench.One ran for 31 hours before stopping,other ran just 30 hours.

Considering a 16610 should have a 48 hour power reserve, but let's just say 40 to remove variance.

That would mean that the winders tested were causing the watches to lose 5 hours of power reserve per day, being on a winder.

So they would stop ticking after just a little over a week if not additionally wound manually. That makes zero sense.

It takes around 650 turns of the rotor each 24 hours to keep a 31xx movement at a static state of wind. According to Wolf's website, a non-adjustable winder does 900 turns per day, so in theory that would add a little more PR each day it's fitted on a winder.

On my own personal winder, I have kept my watch for months without it running out, it continuesly adds a little more power each day, ensuring it's always fully found.

Anything less would be an incredibly stupid programming of a watch-winder, which whole purpose is to keep the watch running indefinitely without having to wind it.

As I also said, each watch is different and it depends on the movement how many TPD (Turns per day) it needs to stay static. Omega as an example recommends 750. Some Patek's only 400. An SW-500 Chronograph needs 800.

So it depends entirely on the winder and movement inside, but I doubt most winders are operating at less than 700-900 tpd, unless there is a specific setting to set, which would then make it a user error.
