6263 power reserve

[scooba]

I have a 6263 and was thinking how long would it run for if it was fully wound ?

How would one know when its fully wound. Can I over wind it ?

My understanding is that you cannot over wind a Rolex, but i wouldn't want to put that to the test. Logically if well wound it should run for several days.

With watches like yours, have you considered watch winders if you want to keep them in good running order and presumably be able to swop them over without messing about setting the time and date etc.

That's only for automatic Rolex. Watch winders are useless for manual wind Rolex.

Thanks for that, didn't realise that this model was a wind watch rather than automatic. Is there any period of time when Rolex moved across or did it depend on the particular model as most subs and SDs older than the 6239 are automatic.

I think i just answered my own question !!

I have four rolex winders for my Automatics .

It did indeed depend on the model; chronograph or non-chronograph... Daytonas being sold up until the 1980s were manual wind, and that was one of the reasons they did not sell so well as people wanted the automatic models. Of course, those Daytonas now command immense premiums on the vintage market!

Thanks, that was very helpful. I do keep an eye on what vintage Rolex models are selling for and in the case of Daytonas i can only watch from a far. £60k upwards for Paul Newman dials is way out of my league.

My 6239 runs about 2 days or about 48 hrs.

As you turn the crown you will begin to feel resistance as you near the end and when its fully wound the crown will not turn anymore. Do not wind the crown anymore as you will break the main spring.

Note: this is for manual wind Rolex not autowind.

Now you have me wondering Scooba. It's 7:00PM, I just put a full wind on mine, from a dead stop, 63 normal turns of the crown. It just stops winding when done, no real tension difference.I'm pretty certain its well over a 40 hour reserve. It's rare for me not to have it wound. Probably a good time to finally check it out. I had a full service done in Febuary, including a main spring replacement so I'm curious how long it runs for. I'll let you know.

Well that confirms Antoinerob's results. After 31 years, now I know,50 hours to the minute. Stopped at 9:00PM tonight. We must have the same watchmaker.

Over wound = a broken stem.

Most people say the watch is over wound when they cannot wind the watch anymore and it is not running.
The fault there lies in the watch not running. Not, how much a person wound the watch.

In other words, the watch was not running and someone kept winding it in hopes of getting it to run.

To restate, "over wound " , is a complete misnomer.

[Antoinerob]

I started a test with my 6265 48 hours ago and it is still running...
Wait and see. I will keep you posted!

The 6265 just stopped...after 50 hours 👍.
Excellent performance...within the COSC specs 😎.

Thanks for the feedback Antoinerob. 50 hours would explain why I have rarely even seen my watch stopped.

Its a manual wind once its fully wound you should feel it just stop, wind clockwise only as they only wind on the forward turn but you can break the winding stem if turned with force once it fully wound..As for power reserve depending if any wear in the spring-barrel and mainspring around 39-48 hours give or take a hour or so.

There are no COSC specs for the power reserve and watches like the 6263/5 were not COSC tested, but the all gold versions were, but exactly the same Valjoux 72 series movement.

[Antoinerob]

Sorry, I did say it wrong. What I meant was that the watch ran for 50 hours and kept excellent time (until it stopped) within COSC specs....!

[Antoinerob]

You are welcome Ralph.
I must say that my watch was serviced a few months ago and the original 727 caliber is in excellent working order thanks to a good maintenance over the years.
