My DSSD only lost half a second accuracy after 30days. I'm impressed!

I would he happy with that performance!

I have read that DSSD's can be slightly more accurate due to the particular movement.

I also agree with Padi that the wandering +/- over days that ended up being a random walk to <1 sec over 30 days total is NOT the same thing as "0.5 seconds per month"

My DJ has settled in to approx. 0.5-1.0 fast per day measured per day when kept on the winder or worn only 8-12 hours per day. Once in a while my wearing it all day (all 24 hours not taking it off except to shower) can on occasions make it go +2 to +3 seconds per day. I like this level of accuracy and consistency, but do not consider it anything more than a fun thing to monitor.

Rolex movements are in a word Incredible.

never had a Rolex that accurate, im sure they are out there. My PO runs dead on if I wear it everyday, and set it on the nightstand while I sleep. I've worn it for 6 weeks at a time before and it within .5 sec everyday

It's not just the watch, probably would vary more on someone else's wrist. I think I just got lucky and got one that was sinked to my activity level.


When I rotate it to the winder and leave it there without wear it gains +2 or 3 a day.

That's impressive. Glad you love your DSSD!

The DSSD has exactly the same cal 3135 that was first introduced in 1988 same as whats in many of the Rolex line up.The only change is now most Rolex watches that use the cal 3135 have the in-house made escapement parts.And no matter what escapement parts the movement has, its only as good as what its been regulated too its that simple.There is nothing magical with the PB or Paraflex they are just a hairspring and shock system.And as long as any Rolex movement made over the past 40 plus years are well regulated there is no reason why they cannot perform well inside the COSC spec.But being mechanical with any movement made, many things effect the running of any mechanical watch.Like wearing habits, gravity temperature,power reserve etc. But lets be honest whats in a few seconds either way out of 86400 in a day, its not life threatening in any way.

My new DSSD has also been extremely accurate. A wonderful piece!

When you say "PO" is that an Omega Planet Ocean ? Are they all that incredibly accurate ?

Yes, Planet Ocean w 2500 movmt. I don't think they all are. I have heard of a few others that run as accurate. Just got lucky and found one that works with my activity level.

[goldrolielove]

my DSSD is +/- 5 seconds a week . Can we trade?

[mjclark32]

That's great accuracy, hope it stays that way. Congrats!
