SDDS & timekeeping

[Rolex116520]

I bought my Deepsea about 2 month's ago and I find that this watch keeps excellent time , I would say by far better then all other Rolex watches I own and have owned.
Would this have to do with the " Blue parachrome" spring? I would like to ask those who have the same watch but especially those lucky enough to own both Sea-Dwellers if they notice any difference. I do understand that the same watch may keep time differently on one individual then another.

How accurate has the DSSD been thus far (+/- seconds per 24 hours)? Has the accuracy varied as it has "broken in"? Do you wear the watch daily? When not worn, do you keep it in a winder?

It's using the 3135 movement, which is in a large number of models, and the effect of the Parachrom hairspring will be minimal, in my opinion. It all comes down to regulation, and it sounds like you have a well regulated watch

Well, I set the watch when I bought it ( 2 months ago) and I wore the watch none stop for about 2 weeks , I now interchange it during weekdays with my 116520 but will wear it on weekends . I take it off at night.
I reset it again yesterday and it was less then a minute slow .
To me that is excellent , much better then my 116520 and 16520 or 1603 .

Less than 60 seconds off over a two month period sounds exceptionally good to me especially since you don't always wear the piece on consecutive days and you did not reset the time in the interim. Congrats on getting a very well regulated sample! Enjoy.

Exactly why I posted this thread as I'm as impressed as you are , but reading some of the other responses it seems that the deepsea is generally keeping excellent time . Maybe because they are all relatively new .

Well cannot see why its any differnt from any other Cal 3135 the movement its only been out 20 years. Its simply down to regulation and the wearer with mechanical watches.

I completly understand what you are saying , what I meant by being relatively new is when a watch is new out of the factory it may run accuratly but with wears and may loose or speed up .

Many factors come into play with all mechanical watches,changes in temperature different wearing habits etc.What will be say +2 on one wrist don't necessarily mean it will be same on another.All Rolex movements since the 10XX series more than capable of a few seconds either way.But to get any mechanical watch to self regulate with no daily deviation they are in the minority.The fact is no mechanical watch will keep spot on time, close yes, but 100% spot on no.As long as any chronometer runs too, or perhaps a little bit better than the COSC norm we should be jumping for joy.

I have owned my deepsea for around two months and I originally set it using an atomic clock.
It loses a second a day which I am very impressed by....

My Deesea is about 7 weeks old and yes, it keeps very accurate time. It could be because it's still new but for now I'm more than satisfied that it's about as accurate as my Daytona.

I own and have owned 3 ( F,Z and now V) 116520 but none have kept time as well as my Deepsea.
Worst was the Z reg that would loose close to a minute a day . My actual V looses some time aswell but seems only adjusting every 2/3 weeks for a minute. I can accept that as I now wear it much less because of the Deepsea . My F reg lost some too , but less then the Z that had no excuse as I wore that all the time too. I wonder if the fact that my F reg still had the thin hands would keep better time with me then the Z reg with fat hands as they both had the same wrist time?

All Rolex movements are more than capable of running to a second or two either way if the are regulated correctly.Regardless to whatever hairspring they have in the movement.Several TRF members have vintage Rolex running +1 second a day,and I have a 85 year old one running +5 seconds a day.
