I'm able to correct 5712 accuracy nightly...

I just bought a 5712/1A and I have noticed something interesting. When I wear the watch, it is accurate within .5 seconds over a 12+ hour span (well within tolerance). However, when I set it down for the night, it loses or gains time based on the direction I lay the watch down beyond tolerance. For instance:

Crown up: loses approx. 2 seconds per 10 hours.
Crown down: gains approx. 2 seconds per 10 hours.
Crown right: loses approx. 2 seconds per 10 hours.
Crown left: loses approx. 1 second per 10 hours.
Face up: gains approx. 1.5 seconds per 10 hours.
Face Down: gains approx. 1.5 seconds per 10 hours.

At first I was a bit annoyed that I could have the watch perfectly accurate to the second throughout the day, but when I woke up in the morning, it would lose or gain about 2 seconds (which is more than double the stated tolerance of +2/-3). But now, I find it somewhat useful in that I simply check the exact time when I take the watch off at night, and if it is fast, I place it crown down, and if it is slow, I place it crown up-- thereby "auto-adjusting" the time overnight.

So basically, although my OCD is still a little frustrated that there isn't an orientation that keeps perfect time, I at least have a watch that will be accurate to within +2/-2 seconds perpetually as it NEVER loses or gains more than 2 seconds during the day, so it is always within 2 seconds of accurate every morning/day, and usually within 1 second...

Anyone else notice this about any of their watches, or am I the only one crazy enough to have even tried to time the differences in accuracy based on watch orientation/positions overnight?

To be honest, I like to look at the dial. Couldn't care less about accuracy.... if I did, I probably would've bought a digital watch of some kind.

You are insane... it's fantastic!

I get what crown up, crown down, face up and face down is but what is crown left and crown right?

I normally adopt the crown up position with my 5164 and anecdotally I lose time. I would only notice when there's 1-2 minutes difference though.

I'm not sure if mechanical watches are for you friend.

Basically, crown right is setting the watch down so that it is essentially facing you, crown left would be the same but the watch is upside down.

Not at all, I have 6 watches and all are mechanical. I just view the precision of the timekeeping as part of the precision of the craftsmanship. I could care less whether the time is right within a minute, but I do care if the watch is precise, just for the sake of the craftsmanship that it takes to get the precision. If that makes sense.

To each his own. Accuracy seems like an odd thing to treasure these days when everyone has an extremely accurate cell phone in their pocket. If I have to set my watch every few weeks that's fine with me.

To achieve accuracy mechanically is an achievement that I value. I could care less about the accuracy beyond that and don't care that cell phones and quartz are more accurate because that is easy to accomplish. Being accurate with a mechanical watch is very difficult.

It used to be, but there are limitations. The tourbillon used to be important for accuracy but today it's mostly cosmetic. We used to have observatory prizes for accuracy but those ended.

My 5164 looses about 2 sec per day but if i leave it face down overnight it catches up. So if i wear it for a week or so.. I can have it close to perfect. There is a difference between accuracy and precision --- and have to let the OCD go.

i have the same issue with my 5712r. Drives me a bit nuts. Loses time when i put it on the left side (remember no bracelet on this one so default option).

On the other hand, i have a 1973 1675 and this is spot on accurate regardless of any position. I had it 3-4 years and never serviced it.

The phrase is ‘couldn’t care less’ – as in it’s not possible to care less than how little you do already.

Well done for spending a bit of time tracking the overnight performance off your wrist, but just make sure the PR indicator is at or near it’s maximum.

So basically you are in 3 seconds per 24hours right? For me it's fine, before I was a little more into accuracy, but now I basically wear each of my watches in rotation, so out of the bank for 7-10 days and back to change for another. So for me when I get a watch out I set the exact time and maybe once every 7-8 days will check accuracy, but I am ok if it's a little off

You're way overthinking this watch ... Set the time, wear it, enjoy it.. After a few weeks if you notice the time is off a little bit, adjust it and move on. Life is too short to worry about these things!

I'm trying to be clear with everyone that I really don't care about the accuracy, I just thought it was interesting that each position varied so much and so predictably.

Very useful post, thank you for the research.
I did the same.

My 5167 (324) for the past 2 months, I am at +1 since I put it on at the boutique.
I know the 240 of 5712 is even better in accuracy.

As long as I'm within the minute I am good so only change time every 4-6 weeks.

In fact I have and my 5712/1A is very nearly identical to yours in almost all regards. Like yours mine runs almost spot on when on my wrist and then either gains or loses a bit overnight depending on what position I put it in. With mine, the same positions gain a little or lose a little to essentially the same degree as yours does. I also find this useful as I can keep the time within a couple of seconds for months - just by knowing what position to put it in at night.

Everyone may look at this differently and that's fine. For me - I would love the watch even if it was not as accurate as it is but the fact that its ability to keep excellent time just adds to all the other things I love and appreciate about it.

Nope. But I take my Patek off when I get home from work rather than wait until right before I go to bed. Hence the 10 hour measurement rather than 6-8.

The watch doesn't know when I go to sleep, only when I take it off.

Haha, I was just joking. I like your post and observations. I also appreciate accuracy in fine timepieces and think it is fascinating how they are able to manufacture these works of art with functionality.
