SD43 bought in July 2020
Running -0.3 SPD on the wrist (loses 9 seconds a month). Resting dial up at night. Highest amplitude of 281 dial up, lowest 238 crown down. Delta of 3.8 seconds.
My mainspring seems to be continually fully wound. If I try to manually wind it at any time during the day (except in the morning), it is fully wound.
