Doubt Rolex movement quality? Come in and see....

Thanks to the people who help make this possible you know who you are

Watch was purchased in 1992 and serviced by RSC Japan in 1998.
No record of service since then.

When i got the watch i decided to go to my watchmaker and have him put it on the timer.
Only bout 10 winds of the crown from dead stop, look at the amplitude , this is crown up position.




Now with the dial up position, this is about 80% of my work day position i have a boring desk job
But look at the accuracy !!!




Just based on the information no one would say it needs a service. And the watch was serviced last century 
I dont wanna open up the back case.
But even so, when i have the chance i am still going to send it to RSC and have it serviced maybe next year.
Will wear the watch for the coming months before i put it on the timer again to check for changes.

Nice Exp I u got there, Bruce Lee.  Tritium dial. I was wearing mine yesterday, non tritium.

I never have any doubts on the brand n movements, I think its 1 of the most robust  movement money can buy. I also don"t want to be drawn into any discussion on service or not to, every 5 years. Its a sensitive issue. regards tony

That will open up another can of worms AGAIN.

Just happy mine is still performing well within COSC standards.

awesome time keeping for a watch that age!

My 7 year old 7S36 is probably running + by the minutes/day!

But the 7s26, 7s36 and their variants are not designed to be very accurate. Even new ones run at +/- 15 sec per day or maybe more. The good thing is (compared to the rollie) you can get it serviced and regulated at a fraction of the cost!!

Yea, a fraction of the cost is why i don't really mind/complain about it...haha

but amazingly, i have a friend who claims his 7S26 does +2 secs/day! Probably a lucky one...but sure gives the Swiss a run for their money! haha

By the way, anybody care to PM which watch shop has this kinda machines to measure accuracy?

Thanks!

I doubt that will be running consistently at +2sec/day for a long while. That's the great thing about a Rolex, as Pete was trying to highlight - superb long term accuracy. If you look at Pete's photo below, you'll see the amplitude at 281 deg. For a watch from the 1990's last serviced in 1998, that's wonderful.....things within are still strong and swinging strong!!!

And that was only with 10 turns of the crown from full stop. Impressive indeed.

Yes, Pete, lots of (or all??) watches start to run a little fast when they wind down (i understand). What we see from your pics is nothing short of impressive. Maybe the deviation in the Rolex is too small to be recorded; so if you have a super accurate timing machine, then the deviation will be more obvious. Still very accurate nonetheless.....

An explorer with nicely formed patina!!!...I've seen picture of a watch like this few weeks back in this forum!
so you're the lucky owner...! Congrats! 
So you did a 10-turn winding, wore and then checked the accuracy?
 

[takashi78]

The owner is me 
Nope, my watchmaker friend wind it up and straight on to the timer.
I was there to adjust my bracelet.
