3235 movement stopped and restarted!?

[carbon888]

I did a search but couldn't find anything, might be too specific.

I've a SD43

Today when I woke up, my watch has stopped, I gave it a wind 2 days ago maybe around 20+ times so I thought that's just normal. I decided to put the watch on b/c I miss wearing it, did the laundry, and just going online. It was on my wrist for around 10 mins and I took it off. The movement started again and is still running for almost 8 hours now.

It almost felt like the movement got stuck and started again? I don't think the 10 mins on my wrist will wind the watch that much to be running for 8 hours?

Should I send it for service?

How old is your SD 43 ?

Try giving it a full wind. More than 40 full Turns of the crown.
Set the time correctly.
Place the watch dial up and leave it until it stops.
Make a note of the exact time it stops.
Now you have the power reserve time and you will know if something is stopping the watch or not.
It’s a very simple test
Try and monitor, without touching the watch, the timekeeping and make notes.
There is a thread all about the 32xx movements …….

To fully manually wind your watch it would need 40 plus full crown turns clockwise only. And wearing your watch does not wind your watch its wrist movement that winds the watch, would doubt if there is anything wrong with your watch.

My question is why did it stop and restart after just being on my wrist for 10 mins? Is that normal?

Thank you

It sounds like it's a simply a matter of you not being active enough to keep the watch wound enough.
Try wearing it more or resort to manually winding it on a regular basis.

Just a little experiment to try to gauge how much winding you're puting into it by wearing as you normally would.
From the time the watch stops of it's own accord, simply put it on and wear it without winding it and wear it for a set length of time(for example 6 or 8 hours).
By that time it will have likely started running all by itself. If not a gentle little shake will start it.
Then take the watch off and set it asside without touching it again and note how long it runs for.
This will tell you if you are moving enough to wind the watch sufficiently for it to run for any given time period

[CharlesN]

Possibly you did not wind it enough and move enough in the very beginning to get your watch really running.

Doing the simple test will tell you if you have a big problem or not.

Regarding said thread just wear your watch and enjoy it, if you want to test your watch just give it a full manual wind try 60 full crown turns clockwise only .Don't worry you cannot overwind it then depending on movement if 31 series should run around 39-48 hours give or take a hour or so off the wrist. If the 32 series around 65-70 hours give or take a hour or so. Even when a watch is fully stopped sometimes after a wind they might need a swirl to start again all normal with Rolex movements.

No, not yet.
How old is your 126600?

I own the same Sea-Dweller and know how to diagnose this 3235 movement, and all others.

First, do the simple test suggested by Charles in post #2.

It most likely stopped because it wasn't wound enough to give you more than 2 days power reserve.

It then started again because doing the laundry produced sufficient movement to wind it enough for 8 hours.

Mine will restart just by picking it up and unscrewing the crown to wind it.

Rolex say these movements have a more efficient automatic winding module than the previous generations.

I can give mine only a few winds, strap it on and after one day of wearing its fully wound (I do have quite an active lifestyle however)

What you've experienced appears entirely normal.

How is your watch's timekeeping?

Exactly this ^^^

OP, You probably just didn’t have much energy stored in the power reserve from your last manual wind.

Based on measurements, 60 full crown turns are not needed for my all 32xx movements.

But more than 20 are

[Tricolore66]

Read the manual.

Yes.

Measurements were done for 4 different watches, covering 3235, 3285, and 3130 calibers.

For my 32xx watches, there is no gain to wind more than 40 full turns.

Thanks everyone, let me do the test before I jump to conclusion
