Rolex Submariner stop moving despite wearing it everyday

[giggss]

Update.

Seem like there is nothing wrong with the watch's reserve power.
11 Sept evening 7pm gave it a full wind about 40-50 rounds.
Watch stopped at 13 Sept evening about 8pm.

It is moving for about 48 hours without me touching it.. after a full wind. Left the watch on table, with the dial facing up. Any difference if I left it sideway ?

So conclusion is nothing wrong with the watch???

Sounds fine with me... perhaps you were just not moving enough to wind it up properly

If you rest it sideway, it might slow down a little bit and nothing else

Another possibility is that the hairspring is a little bit too thick for you, so it was hard for you to wind it up when you wear it

Saw this somewhere... thickness after multiplying by 3 times does affect quite a bit

M=Ebh3/12L *ψ
M=hairspring leverage ratio
E=hairspring elasticity
b=hairspring width
h3=cube of hairspring thickness
L=hairspring length
ψ=hairspring winding angle

wow the equations!

does it mean i need to shake or swing my hand more often?

...does it mean i need to shake or swing my hand more often?

in short: yes! (or wind it up every day or two.)

Yup. Your watch is perfectly fine. Glad that the test worked out.

Yup. Just swing or shake more but if it looks and feel a bit cookoo, just stick with manually winding it. But I am not sure if frequent screwing the crown in and out might cause the thread to worn off faster.

thanks for the suggestions to test it..
guessed i will have to swing and shake my wrist more with the watch on. lol

winding it every other day seems troublesome and i don't have a good feeling to keep pulling out the crown leh

"backthread" before engaging = no problems (for me anyway).

to be fair, the rolex winding system is not inefficient so you must be simply not moving around enough to sufficiently wind it up... you can probably get an auto-winder for your watch when you don't wear it.

+1 Same here.

But not everyone are careful most of the times and tend to overlook the simplest of things.

means turn backwards before turning clockwise to wind it ?

[taxico]

counter-clockwise slowly. don't turn clockwise until the crown has dropped into place. i usually do it with my watch off my wrist and one thumb against the crown.
