Night time resting position

In my experience, with my 1 mechanical watch, it’s most accurate and reliable when worn a lot. It’s like my body acts as a supernatural tourbillon. It doesn’t like sitting.

Does she ever wake up and catch you?

Dial up is the one position that creates less friction, I always lag my watches in this position regardless if it helps or not accuracy.

I just use an Excel spreadsheet.

I wait a month of normal wearing for it to break in.

Then I'll check the time in the morning, wear it all day, then check it at night and write those numbers down.

Then I'll rest the watch and check it in the morning and write that number down and repeat the gains or losses each day and each night with each resting position.

After I have a decent data set, about 3 points of data for each method of resting I'll decide which is best and stick with that indefinitely until I notice a weird deviation.

With my current Tissot it gains about 3 seconds resting crown up over night then loses 3 seconds as I wear it throughout the day. I found that other resting positions lost more seconds generally. It tends to stay around +0 to +1 seconds over 24 hours and generally very accurate with this method.

I find the data and testing to be interesting but I can see where others wouldn't.

I'm at +1 seconds over a week now but I haven't been wearing it a ton which tends to slow it down. So it's right around what I'd expect. Overall I prefer it to be slightly fast and never slow if I can help it.

I highly recommend the phone app “WatchTracker”. It will make you life a whole lot easier, and has some cool graphing features.

WatchCheck is also a great app

i can assure you that the 313o is affected by its resting position.

of course it is, but not by the 1960's card that the links refer to.

+0.4 276 0.0 dial up
+0.9 275 0.0 dial down
-3.4 239 0.0 12 up
-1.6 241 0.2 6 up
-1.3 239 0.0 crown up
-3.4 241 0.2 crown down

3187
(-1.1 spd on the wrist resting crown down at night)
rate amp B.E.
0.0 307 0.0 dial up
+0.1 289 0.0 dial down
-2.7 262 0.0 12 up
