8 - 10 day timing results for the Apollo 11 Moonshine (cal. 3861)...
I will copy and paste what I wrote in the thread started by Art below.
I fully wound the movement and set the exact time against the atomic clock application I have on my Note 10 plus. This was done at 8:30 am (Paris time so GMT +1).
I set the watch down last night prior to going to bed dial side up on my dresser. When I rewound the watch this morning around the same time and checked the timing against the atomic clock app, the watch seemed to have gained approximately 1 second since setting it yesterday.
