New watch regulation chart

[CharlesN]

Yesterday I bought myself a new DD 118135

Before I purchased the watch I asked the AD to give my watch to the watchmaker to have him do a timing test and give me the results.

This is what I got.

It should be simple enough for me to self regulate the watch having this as a starting point.

The AD I went to is not only an AD but is also the official Rolex Boutique in London. The watchmaker is obviously Rolex trained and is very competent.
I thoroughly recommend to anyone buying a new watch from an AD to ask them to do this simple and quick test.

I know that my watch was sitting around at the AD before I purchased it for a few months at least.

I will go back to the AD in a couple of months and have the watchmaker do the test again.

Things will be different, and, hopefully better once the gears get moving and the oils inside get moved about.

We also performed a day and date change time ... Both mine change 42 seconds after midnight.

This is what I received from the watchmaker ...

I wouldn't expect it to get be better than +0.4s/d

Cannot understand why you would want to go back in a couple of months you should be jumping up and down with your present results.Will you continue to go back every few month for a timing check.As while the test on a machine with a full wind will give a good result.But on the wrist it could vary slightly from day to day with your on wrist wearing habits.

Very cool, but too "geeky" for my taste to use as a point of reference for self-regulation...

Completely useless information. Why would anyone care about the accuracy of their watch?

No I will just go back in 2 or 3 months to see how it has settled down to life.

I will wear it every day and place it in one of the positions overnight to keep it as accurate as possible.

I am suffering from a very bad dose of WISitis.

I am fanatical about accuracy.

I have managed to self regulate all of my watches to +/- 0 seconds per month using the self regulation method.

Many years ago I found this ... An official Rolex document. It seems that I am not alone with my strive for perfect accuracy.

I would recommend checking real would results of the resting positions for the purpose of regulation. My watch is pretty far off from the timing analysis I received, and is not consistent from one day to the next. Sometimes loses and sometimes gains rested in the same position.

Whats the point off having a watch if it isn't accurate ?

It is possible your watch has become a little magnetised.

Any AD or watchmaker should be able to sort that out within 5 mins.

Already done the demagnetizations

Way to go Charles.

I use my TimeGrapher to log all positions and then use the best position to correct the final wrist result.
