newly serviced Exp II running fast

[zimv20ca]

my 16570 came back from the Toronto RSC 4 days ago after a full service. it's running nearly 4 seconds fast / day.

i've been wearing it 16 hours / day and have it on a winder overnight.

should i give it a few weeks to see if it comes to w/in spec, or should i expect it to be more accurate immediately? i paid for it, i would like the accuracy.

I believe it's in spec for COSC. It's also an older watch is it not? I'd be happy with +4. I believe the COSC spec is -4/+6. Winders also aren't what Rolex recommends for regulating watches.

Wait on it. Let your wrist be the only winder.

What is that program you are running to track the watch?

you're right, i don't know why i was thinking it should be -2/+2.

regarding the winder, is there consensus here? though i have been wearing it every day lately, soon it will go back into a rotation.

I wear my EXPII maybe 4-5 hours a day since I don't wear a watch to work and it has plenty of power the next day and no need to put on a winder. If you wear 16 hours a day then for sure it would not need to be put on a winder at night.

Personally, I don't use a winder and probably never will.

As to your watch running fast, maybe it will settle in after a short time.

I use winders on mines, keeps the oils running!

As Lee said above, +4 seconds a day is between the COSC -4/+6, so it is technically running within specifications.

I am a rookie when it comes to analyzing these graphs.

The first graph makes perfect sense, but the second one doesn't.

Why does the second one increase and decrease so much?

Thanks.

that's graphing the data points against the line for the average, and then connecting them.

I think that might be for the newer 6 digit or later references.

As previously stated, wearing your watch 16 hours should allow you to rest the watch during the night rather than keeping it on a winder. I have recently discovered the orientation the watch is left in during the rest period (crown up or Down etc has a massive effect on seconds per day (when I say massive it’s only about +-2 seconds per day but that can halve your daily precision value!

Before you stress, avoid using the winder x2. Wear, and then evaluate. What is the environment and area you keep the winder in like, and the winder itself?

the winder is from Boxy:

https://www.amazon.ca/gp/product/B01D93N38A

it's in a spare bedroom, normal apartment heat and humidity, set to 650 TPD, bidirectional.

i left it off the winder last night, dial up. no real change in performance.

[Turpentine]

....specifically the 5-digit series, store overnight on the 6 o' clock lugs (w/ crown facing right and dial facing straight ahead).

In my experience, if I leave it like this for 10-12 hours, I tend to lose about 2 seconds.

However, YMMV...

The "oils" thing with winders is a myth. Winders are great for watches with complications that need resetting. Use a winder if you like--it's purely preference.

As far as accuracy, they usually try to make sure you run a teeny bit fast. Anything but slow. Slow is bad.

[Tools]

Most qualified watchmakers can regulate your watch to be more precise if you are not satisfied. If you're not happy, get it regulated, or send it back to whoever did the work; I'm sure they want you to be happy.

Personally, at 4 seconds, if you have a watch in rotation it's not suddenly going to "go-off" while you are wearing it, and easily re-settable next go-round.

I don't use winders for my watches. I just pick them up, wind and set them to the current time, and off I go until the next time.

[Z-Sub]

I’ve brought watches to RSC in Beverly Hills and got free regulation several times

[1WatchDawg]

Agreed, if your watch is in rotation and in COSC specs no big deal. Set it wind it it up and go!
