Caliber 3130 self regulating experiment

[JMGoodnight369]

I did a little experiment with my 114060 (2018) caliber 3130 to see how accurate I could keep it and for how long. I’ve read post on here referring to resting positions not having a lot of weight in regards to accuracy with the modern movements having the parachrome hair spring. On wrist 24/7 I was keeping about +1.5/day. I went to resting dial up at night. A solid 8 hours as I was trying to keep some variables during this. Dial up I would gain say an extra +.3 to .8 per night. Crown up I would gain just over 2 seconds per day. The sweet spot seems to be crown down. After 31 days I’ve kept an average of +0.1 per day. At the maximum I’ll get half a second fast and then at night it slow back down. So far I’ve only gained 3.9 seconds after this entire month. Have to say I’m very impressed. I did the same with a 214270 caliber 3230 and it always hovered at +2 per day no matter the resting position. My older 114270 caliber 3130 was very similar to the sub. It kept better time in my opinion compared to the 3230. I know not everyone on here is super into accuracy and even get annoyed with such things, but it is one of the biggest selling points for me with Rolex. I really appreciate something that has been designed with such fine tolerances that it can sustain for such long periods of time.
