What are your Deviation rates on your Rolex's per day?

[Matman167]

Please I need some input, what kind of Rolex do you all have and what is the avg rate of seconds gained or lost per day. I have a two tone Sub 116613 and my rate is about +2 seconds a day. my sub 116610 SS is about -2 seconds give or take a sec. My question is, is this the avg for everyone else as well? do i need to bring it in to have it looked at? thanks a bunch everyone!

[ref1655]

-1.5 seconds/day...watch/1655 serviced 2 years ago at an independent RSC.

[Dr. Prunesquallor]

BLNR 0.5 sec/day

[toolr]

I keep my 114060 on a winder when not worn. It averages -2.5 per day positioned crown right (12 o'clock at top), at crown left (12 o'clock at bottom) it averages -1.5 seconds per day so I leave in the crown left position.

[Rolexbiker]

Never thought to actually check them to the second........It keeps good enough time.

[beshannon]

I've never been late so I am good

[Aussiexplorer]

16570 plus three seconds per day.

[jackass266]

To be honest, I rotate between 4 watches and wear them several days at a time. I don't care about the few seconds it has gained or lost in the few days I wear it seeing as whenever I take one out of my collection to put it on, reserve has run out and I have to set it again.

Futher more, whenever setting the watch I don't look at the seconds just the minutes and hours.

My 16710 (3185 movement) has been +5 seconds a day almost the entire time I've owned it. It was last serviced by RSC Tokyo in October 2014. It was sent to RSC Tokyo again in Feb of 2015 because it decided to go +15 seconds a day out of the blue.

As it sits now, +5 a day.

Mine are well within COSC tolerances

My brand new smurf is currently +1. In my experience new Rolex movements are generally a tad fast and then settle down after a few months

Your watches most certainly dont need any looking at, both watches showing around 99.998% accuracy. Remember this the escapement of a mechanical watch in 24 hours pushes the gears 432,000 times. Since a day has 86,400 seconds, even a watch that runs five minutes fast or slow each day has an accuracy of over 99.6 percent! A finer mechanical watch that gains or loses about six to nine seconds a day or about a minute a week has a breathtaking precision of over 99.99 per cent. This is still very high precision, given the fact that the movement is constantly affected by the earth's gravity, metal expansion and contraction, temperature variations, subtle changes in lubrication and friction, shocks, and so on.The fact is that no mechanical watch made will keep 100% perfect time, very close yes but perfect no.The COSC spec is a average of -4 to +6 over 24 hours. Now this new specification by Rolex so they say they further test too a AVERAGE of -2+2 seconds but this is not a guarantee for life its just a specification .So most Rolex are 99.994% accurate what more could anyone ask from a mechanical watch.

This.

When i got my SubC a few months ago it was about +2/day for the first few weeks, last time i adjusted it about 3 weeks ago, and it's still second perfect, it amazes me how something mechanical can be so accurate.

[ppalasthira]

SubC +1 a day.

[Rolex fan 61]

There are 86400 seconds in a 24 hour period why are you worrying your watch is VERY accurate just wear it and enjoy it and stop worrying

[s7horton]

My 16613 from 2001 that has never been serviced is about +0 per day. My brand new Hulk is about -1.5 per day. My wife's brand new OP was +17 per day so I took it to a local authorized service center, they put a new main spring in it and now it's +2 per day.

[Igerswis]

All these people commenting on how many seconds there are in a day and 99.9998767866% accuracy are missing the point.

Rolex are designed to run within COSC specification. We pay for this tolerance level. Therefore if a watch falls outside of this then it is fair to question why and if it's in warranty then Rolex will adjust it accordingly. Otherwise you'll have to get it serviced.

Don't forget, Rolex market the whole accuracy level with their 'superlative chronometer' phrase.

Not at all but good luck to you and your lost seconds

100% agree. Paying 1000s for 'the best' to be told that one's not supposed to be bothered when 'the best's' performance turns out not to be 'the best' makes no sense to me.

Over a series of separate multi-day measures over the last few months, my 16710 has shown a maximum gain of +1 per day and a maximum loss of -1.1 per day; and most measures cluster around -0.4 per day. The 'extreme' measures seem to be activity related: such as chainsaw use or kayaking.

The snapshot is a measure taken just now of the last 3 days. Not too shabby :)

I think that you missed the whole point of the OP post.

His runs 2 seconds off a day; within any tolerance expected from a mechanical watch. The question was "what does everyone else see" and "should I have it looked at".

Besides, Rolex are not designed to "run within COSC specs". They are designed to be better than that. COSC is an independent test needed in Switzerland to be able to legally put "chronometer" on the dial; it's not a stellar timing guide.

I would advise having it regulated to see if that improves the accuracy before I would pay $600+ to service a watch just because it's running just outside COSC.

[s7horton]

My colleagues use their iPhone's or Quartz warches to tell time - where accuracy is crazy high. If my watch is a few minutes slow because it's losing some seconds per day, I look like an idiot for being late to a meeting.

It's not the end of the world, but as was stated, we pay for accuracy. My personal preference is for my watches to be fast. It's real easy to pull the crown and stop the watch for two second to get back on track. If it's slow, that's a different story.

When I read the first paragraph I was sure this was a joke (and I chuckled accordingly). Then I read the second paragraph and realized he was serious. Do you realize how many days of running a few seconds slow it would take for your watch to lose a few minutes? I'll do the math for you.

If it's losing 3 sec/day, it would take 2 months of not resetting your watch for it to run 3 minutes slow. If it's losing 5 sec/day, it would still take over a month before it was 3 minutes behind. May I suggest making it a practice to arrive at meetings a couple minutes early, and not to the second? That's a good way to keep from looking like an idiot.

By the way, my 16710 is -1 sec/day.

I've never checked mine.

Well my 16710 was running about +15s / day...so it's off to RSC (Toronto) today! Last service was 2008 so it's due.

[Dr.Brian]

Works fine. That's as close as I can get on any of them.

[hlippy4]

! month old or so Datejust...better than +1 per day....pretty amazing!
