New movement accuracy

[Juantxo]

I’m truly impressed with the new movement in my Pepsi. I bought it some ten days ago and so far it has deviated exactly 0 from the US atomic clock.

I wonder how long it’ll stay that way but no doubt Rolex has done something very right with the new movement.

Yep, my DJ41 is about spot on....

Both of you must have a watch in a 10million.

Congratulations on an outstanding watch

To be clear, that kind of accuracy is not limited to the very latest movements.
The last generation movements were also capable of equivalent accuracy.
Let us know how it goes over the next couple of months?

From a technical perspective I’d describe a watch that achieves a daily rate deviation of 0sd as ‘evenly inaccurate’.

My Sub Date is dead on over 3 weeks now of continual wear

My DD40 is also spot on after almost a month of wear

I think Rolex tightened their quality procedures.

They say now + or - 2 seconds a day. They are well within that with my newer models

How is this even possible? Your watch is not functioning correctly. If you are putting is down flat, it is supposed to gain few seconds. If you put it side ways with crown down, it is supposed to lose few seconds. Apparently that functionality is not working in your case.

Then you must have two watches in 10 thousand million,as I would say it would be impossible to have no deviation in any mechanical movement for 3-4 weeks..

My SD43 which over a recent 20 day measurement with the watchtracker app, taking a measurement at least twice a day, is on average +0.1 spd. The slowest deviation on any one day was -1.5, while the fastest deviation was +2.2spd. Over 20 days to have an average of 0.1 spd fast is quite remarkable.

Maybe one in 20 million lol. All jokes aside it’s definitely an accurate watch. Mine have always been a few seconds off daily but always within spec so I’m still super happy

My 2018 DSSD JC has settled after adjustment to less than +1 sec/month.

Also like the longer power reserve. Allows me to wear it all week then rotate my other watches over the weekend and pick it up Monday AM good to go.

Nobody is claiming there's no deviation.
Just that each point in time the watch is checked it coincides with the reference.
Surely that's good enough for us mere mortals?
And we ought to celebrate that at least for what it's worth to the owner and for the remarkable accuracy it displays for the broader watch enthusiast community as an example of what's achievable

Absolutely

It's quite remarkable. My Pepsi after 3 weeks has lost about half a second. Yes. Half a second in 3 weeks!

I do not wear my watch 24hrs a day. There is very, very slight deviation, less than a fraction of a 1 second plus or minus depending on it's position. On the wrist during the day, it appears to basically be spot on. Of course there are so many external factors in play so if there is some sort of change it likely can be attributed to that.

The 3135 movement in both of my subs is so, so impressive due to the watchmaker's regulation, one of them regulated by the master watchmaker at a RSC.

I think it has a lot more to do with the actual watchmaker's skill and elements of luck rather than the "Pepsi movement" vs the 3135 or 3185 movement.

Over the next few years it will certainly change but these movements vs some of the older movements especially those found in the ladies DJs, for example, are less likely to change significantly.

Congrats on the Pepsi. My favorite reference right now!

Why would you be putting it down at all? The 1983 Submariner I bought last month hasn't been wrong by more than a few seconds since I took it out of the box [from Bob's Watches]. But I basically never take it off except for rough things like tinkering with my car, etc. Then it goes in my pocket.

My new ex2 has been running right on the last two week. My wife’s tt Sub has been running half a second fast per day.

They say in "Utopia" one doesn't need a watch to tell what time it is. Juan.

I have two Patek watches which are also extremely accurate. However, I must point out that those two watches have been adjusted by an exceptional watchmaker in NYC, as the PP (Stern) service in NYC is plain awful.

The Pepsi has been spot on since out of the box two weeks ago or so.

+1

[FlyDuc78]

my DJ41 is about -1 sec this week.

[SS Oyster]

3235 in this gains about 3 secs per month.
