Daily Error of Rolex

[tuantuanbo]

I have been wearing my Exp I MK2 for 2 month. Overall, I am totally impressed by the quality of the fine time piece. Classic design, smooth polish, high accuracy. Every time I look at Exp I, I am always impressed by this high end time piece. It would always take a few seconds before I realize I need to read the time...

The most impressive aspect is the accuracy of my Exp I. There are a lot of posts on watch accuracy across the web, especially our TRF. According to Rolex advertisements, average daily error is +/-2 second, which is far beyond the error by other standards.

With that in mind, my Exp I have been running extremely accurately. In the past 2 months, cumulative error is within 1 second (in the whole month, not average per day)... The daily average error would be lower than 0.02 s per day.

Is this common for Rolex watches? Any ideas on the reason why my Exp I has so high accuracy? Simple function (no date, just time)? Shock resistant function?

Mine has zero deviation over 30 days.

Last time I checked my 5513 was August 1982 just checked today in all those years of continuous running has gained 0.99999000 of a second.Like all movements no matter the brand or what movement it has in the case, its all down to how good its been regulated to match its owners wearing habits.

Just luck of the draw. As long as its within -2/+2 its all good.

Mine deviates close to Plank's constant, 10 to the minus 43 seconds.

My new Sea Dweller 4000 is the same way extremely accurate. Somewhere along the line Rolex has figured accuracy adjustment out and now offers a better adjusted watch.

I guess 116520 isn't nearly as accurate as your watch. It has lost 4 seconds over the last month.

I just pulled my Daytona off the winder - been there since early March. Was 60 sec. fast so within COSC.

Last time I had it on winder that long it was within a couple of seconds. Hmmm...

I blame the Wolf winder

Its all about the movement my friend.

Theres a reason why its called "superlative chronometer". They invested so much on research. Even the lubricants they used is in house.

One of rolex strength why their movements are accurate is their Balance Wheel. Rolex uses Glucydur Balance Wheel , resistant to shape changes and temperature.
Less expensive brands use a bimetallic balance wheel.

Rolex uses Kif or Parashock shock mechanism, in explorer model they use Parashock mechanism, on my Submariner, Kif mechanism. Only rolex uses this shock mechanism. Other ETA movement uses Incabloc. The former are superior than the latter.

Lastly rolex uses Parachrom Blu hairsprings on their movement.. Resistant to shock, temperature changes.
