Watch positions at night off wrist???

[Paladin]

Does anyone recall the various watch positions and their net effect of +/- time? I have seen it a few times but old age is getting the best of me and I can not remember where.

Thanks.

Not sure where it is on this site but here is the regulation guidelines:

Summary:

1. To gain a few seconds, lay the watch flat face-up overnight.

2. To lose a few seconds, lay the watch vertically with the crown downwards overnight.

3. To lose a few more seconds, lay the watch vertically with the crown up.

In my experience those old Rolex literature guidelines no longer apply. 

The 3135 in my Sub C seems to vary only ever so slightly by position. The "fastest", dial down, has it stay the same, or lose maybe a quarter second overnight. The slowest, crown down, loses between a quarter to half a second. The rest are very close to the - 1/4 second of dial down. Extremely consistent watch for position.

I reset my Sub about once a month anyway, so I only leave my watch face up at night. I'm not really interested in trying to self-regulate...

I've had several over the years & never did have one that kept very good time.

Modern Rolex's use an overcoil balance spring. This diminishes most passive positional regulation.

MOST being the key term.

I, for one, know that the various positions work quite well for my Sub C.

Dial up runs faster, crown down slower.

Also on the winder it runs slower

My sub C runs slower on the winder as well.

Yes, winder is slowest for me too.

I have a 16753 that runs spot on all day long on my wrist and then looses 3-4 sec on my desk overnight.

I had no Idea about any of this! The things I learn here haha!

Hit the watch with a large blunt piece of steel!! (hammer is good) or the dish washer, that will slow it down real good :-)

It was around 200 years ago that Breguet invented the overcoil hairspring design.And Rolex have used the Breguet over-coil design on all their hairsprings for many decades.Although then not in-house made but made by Nivorax Far, part of the ETA Swatch group.Now Rolex has designed there own metal called parachrom for the in-house over-coil Breguet type hairspring.

2007 Sub ND here and I can report that the self-regulating positions don't make more than a second or so from position 1 to position 3.

Gains about 10 seconds a day - but that's because it needs a service.

I tried the hammer (ball peen) maybe it's the dishwasher it's missing. Of course if you re read my post, the watch is already slow by 3-4 sec a night. Doesn't that mean I want it to speed up a bit?

I have actually found that my 16613 runs faster if I don't wear it every day and it is operating more often towards the end of its power reserve. Sounds counterintuitive, huh?
