·My Speedmaster 1861 005 was bought brand new in 2020…I’ve taken some readings using a Weishi 1900, just wondering how any experts reckon it’s running….let the watch sit for 15 mins before DU reading then 3 mins in between readings to settle and 3 mins check in each position…did a full wind test and 24hour test….it ran for a full 50 hours before stopping…..Lift angle 50
The watch was left untouched DU from Full wind until it was tested at the 24 hour stage..
Hope you can read my bad writing
Full wind sd +2.7
24 hour sd +5.5
