How to affect the accuracy of your Rolex by positioning the watch while not in wrist?

[hoowee]

Hello, I’ve been years away from this forum. I’ve tried to find the info about this. Years ago there was even an info card how to get your Rolex to gain or lose some seconds by keeping the watch in different positions while not in your wrist.
Could please help me to find more info and discussions about this?
Thank you in advance for your help. Henry

More or less, if you want your watch to gain a few seconds overnight, leave it dial up. to lose a few seconds, place it on its side with the crown down. If you need it to lose more than that, lay it on its side with the crown pointing up.

This. I have done this with my submariner date for the last two years. It loses one second during the day normal wear, and if I place it dial up, it is the second fast in the morning. So you can keep it perfect that way. Of course, every watch may vary, but this is what has worked for me. If I find a link, I will post it here.

Another vote for the above. This is how it works in my collection.

I don’t worry about it, but I don’t wear the same watch daily, either. Good info, though. Thanks!

Always interesting to see how the position off the wrist can have different results with the timekeeping

I have to say I don’t find the modern movements, especially the 32 series to be especially prone to different positions adjustment.

That's because of gravity this is why they are tested in 5 different positions and temperatures to get the Swiss chronometer rating to mimic when wearing on the wrist. But still many variables like owners wearing habits state of mainspring power reserve plus many others. But in the real world no mechanical watch made at any brand or price will keep 100% perfect time. And even in different resting positions off wrist might only differ a second or so out of 86400 seconds in a day.

Awesome. Thanks. I did not know this

What happens when you leave the watch dial facing down?

Nobody knows because then you can’t tell the time

The reason the watch loses time when placed crown up or down is that the balance wheel pivots experience increased friction upon their bearings in these configurations. This slows the action of the balance ever so slightly.

In a dial up or dial down position, they are resting "symmetrically," for lack of a better term, in their bearings, and are therefore prone to less friction.

Therefore, dial down would be similar to dial up.

Thank you, I sort of thought this might be the case
