EXP II WatchTracker
As some of you probably know I bought an Explorer II White dial 226570 which has a 3285 Movement a few days ago.
I have used an iPhone App to monitor its timekeeping over the last 3 days. (Actually 72H: 27M: 32S). I started at 22:00 Hours on 11 July 2021.
These readings were taken during a Power Reserve Test.
I wound the watch fully and then left it dial up and undisturbed until the power ran out.
The Stated, by Rolex, Power Reserve is 70 hours approximately.
The actual length of the Power reserve was 72 Hours: 27 Mins: 32 seconds.
I have attached a screenshot of the WatchTracker screen which shows the watch gaining time at the start only to loose time as the Power reserve ran down.
The error from the start peaked at +3 seconds after 49.5 hours
After about 69 Hours the watch “Redeemed” itself to come back to almost a Zero error.
It continued to loose time after 69 Hours until it finally stopped completely at 22:27:32 on 14 July 2021.
Before you say what a great watch this one is it shows that there is a problem in that the watch gained and then lost whilst unworn, So , What would happen when worn. I expect the timekeeping would be pretty good and constant but the 70 hour Rolex Power Reserve becomes a bit pointless if the error can just creep up or down at such a rate.
We often read on this forum that unless a picture is enclosed “It didn’t happen” so with pleasure, I have attached below a picture of the WatchTracker main results screen.
This really does show how useful the App can be for showing up errors and timekeeping qualities.
This is the “Stopped” watch in question ..
