Perfect 0.0 Accuracy After One Month: Rolex Amazingness

[mrmahdi]

Greetings,

I’ve written several posts on the accuracy of my Datejust 41 (3235 movement) and I decided to see how accurate my watch can be after a month.

After 30 days, it is 0.0 accuracy. Not a second gained or lost.

To be transparent, when I wear my watch, it can gain anywhere from 0.3-1 second a day (which is absolutely amazing). At night, in its resting position, it often wipes away what the watch lost during the day. Hence, after a month, perfect timing.

I mentioned in previous posts that I had my watch regulated by a watchmaker after the RSC failed (twice) here in Beverly Hills in making it accurate. I do believe with regulation and resting positions, the watch can get as close to 0.0 accuracy or even attain it like I did.

That’s great.

My 32xx experience:

2021 DJ41: much like yours
2021 DSSD: was -1 or 2 from new, until 2 weeks ago, when it started slowing dramatically, just sent in to RSC NY (they received yesterday and I'm waiting to hear from them)
2023 SD43: so far, knock wood, about -1/+1, still pretty new

3 watches now with the 3235. All have started our spot on and 2 have gotten way out of spec around the 1 year mark (losing 10+ sec/day). 1 of those watches has been back to RSC twice in 4 years. The third I’ve had for 4 months now and it was spot on first month and now at -1.25 sec a day. I’ll just wait until way out of spec and send it in like the others.

Have had tremendous experience with 9 different 32xx.

Hopefully the service from the RSC in NYC will be a lot better than the one I had in Beverly Hills. From what I heard, the RSCs in Dallas and NYC are pretty good.

Just some advice: once you get watch back from the RSC, if it’s running 2 seconds or more a day, it can be regulated to be better. Although two seconds a day is “technically within specs” (and for many people that’s perfectly fine), if you want better accuracy, newer movements like the 3235 can attain extreme accuracy. Either you can go back to the RSC or go to a reliable watchmaker to regulate it.

Could be you didn’t wear one long enough for a bad one?

[Mystro]

My over a year old now LVc is at 0 seconds in almost 1.5 months now and counting. No problem with over 7 different 32 series movements. These movements don’t deviate much if at all in varying resting positions. Maybe I can squeeze 0.25-0.50 seconds a night in their most extreme overnight resting position.

I mean over a year, who knows.

Averages:

wear + dial down overnight = +1s
Wear + Crown up = -1s
Wear + Dial up = 0.5s

Play around with position = 0.0s

Only 5 months old ,so Master 3135 will be the judge .

[garyk]

I know some of you guys demand precision out of your fine Rolex watches. I’m really only concerned I can set them each time I wear one and it will continue to run and tell me what time it is until I take it off. Less stress for sure.

My DJ 41 is running the same as yours. Just confirmed it this afternoon. Running great. And I really love wearing the 41. So comfortable.

The Datejust 41 for many people can serve as their one watch collection since it’s so versatile. No wonder why is the best selling model Rolex there is.

Very similar to what you have. During the day, I can lose up to a second. Resting position at night, gain a second. So everyday it ends in a watch.

Over extended period, some of my quartz watches can lose or gain time. So a Rolex watch can be as accurate if not more accurate than a quartz if worn and rested in the same pattern for an extended period of time.

I really am impressed at the 32xx movements. I know early on many complained of so erratic issues that some of the watches were experiencing but for the most part, the movements are almost as accurate quartz or at least the Spring Drive movement in Grand Seiko watches.

I tell people that if you have a 32xx movement watch and you’re getting over 2 seconds a day, then get it regulated or even an overhauled if need be. If you get it back from a RSC and it’s getting right or a little over 2 seconds a day, go to an independent reliable watchmaker to get it regulated.

Glad to hear your DJ 3235 is running great! I personally wouldn’t hesitate to buy a 32xx. Your watch is running even better than my 31xx movements.

I’ve now been wearing my sub for almost ~2 months straight and I’m +5 sec (3130 movement). My 3135 DJ seems to run a bit better than that over the same timespan.

It’s interesting to me that the +2/-2 sec/day rating could mean that after a month you could be running +1min or -1min and still be considered within tolerance but the reality (in my experience) is that these watches run so much more accurate than that if worn daily.

[saxo3]

Just because a 32xx watch runs very accurately it does NOT mean that there isn't a problem with its movement.

It has been shown so many times that the caliber amplitudes, especially in the 3 vertical positions, can drop below specs and the watch still keeps very good time but then, after a little longer, timekeeping goes really bad.

Two concrete examples: an absolute timekeeping of +0.1 and 0.0 was easily achievable over several months for these two 32xx watches:



BUT, both watches (shown above) had the 32xx "virus" already at that time and were sent to RSC due to very low amplitudes in vertical positions, i.e., less than 200 degrees after full winding!

@OP, do one simple experiment: get your watch measured on a timegrapher and post the results in this thread.

Perhaps this depends on the size of one's collection or wearing pattern. If wearing for only a week the accuracy would be a non-issue (eg. wear a different one each week.) Over a month it would be more interesting.

My experience as well. If the watch is outside the +/-2s spec, get it checked.

Is the low amplitude merely a symptom? The watch will certainly fail after such a discovery? If it's still accurate.... then why does it matter? (Just wondering)

Interesting idea. When I bought my JC Deep Blue in 2015, I didn’t take it off for weeks, maybe even months. However, I don’t recall noticing any change in accuracy but maybe it’s because I’m not obsessed with that?? You make a good point and I think I will try to wear them longer and watch them a little closer. Thanks

Good questions

Low 32xx amplitudes are the key observable to determine if a movement has caught the virus already or not yet.

A 32xx will not fail after such a 'discovery', but the owner will know that his watch will develop serious timekeeping problems in the coming weeks or months.

It does not matter when you discover it but you can be sure that the movement is sick (or not).

Anyhow, I do not want to spoil any accuracy party! But to say "my watch is 0.0 after a month" (or a week) is meaningless because it also depends when exactly you are reading it.

If the OP would have shown a Watch Tracker result then we all would see that his DJ41 (3235) is oscillating around 0.0, which is absolutely normal due to positional rate differences (as he described in post 1).

Look at my graph for two 32xx watches in post 20. They showed this excellent timekeeping but were already sick.

[whatsthetime?]

What I don't understand is that Rolex states +/-2sec/day after casing under laboratory conditions, but the green seal means it's COSC certified to -4sec to +6sec or up to 10sec per day which in their [Rolex] eyes is an extraordinary requirement. So I just don't understand the issue with if the watch is running within these specifications as stated?

I never had a watch with the 3135 movement but I keep hearing good things about it. But the accuracy of the 3235 movement just amazes me and I suggest you get one. If you do get one and it’s over the superlative chronometer specs, a regulation will do the job. The main issue with regulations that it’s a hit or miss at times and when it is a miss, you gotta go back to the watchmaker to tweak it a bit until it’s right.

Prior to having my watch regulated by a watchmaker, I actually had my watch serviced TWICE by the RSC in Beverly Hills in a year. The watch is from 2019.

Any amplitude issue was apparently resolved by the overhaul and the Watch ended up being around 2 seconds fast a day (other days faster).

I didn’t like that so I went and got it regulated by a watchmaker and it has been consistently close to 0.0 ever since.

Now regarding the known issues of the 3235 movement, I acknowledge that (since I had an overhaul done at the RSC). When my watch was being regulated, I was there with the watchmaker while he was tweaking it to my satisfaction. He ran it on a timegrapher and stated it was running fast (of course) but I asked him if he could make it half as fast (thinking it will be at least around one second a day). He did that but to my fortune, it was closer to less than half a second a day.

[saxo3]

Thanks OP. In another thread you mentioned using Watch Tracker. How does its graph look for the 30 days of your DJ41 which you present in this thread? A simple WT screenshot as in post 20?

I can read, smart ass. Then why the COSC seal, to cover their asses?
