My 50th Anniversary arrived a couple of days ago. Here is with part of my humble collection.
I set them all to 12 o'clock - and 00 seconds- yesterday (including the Navitimer) this is the comparison of all 4 watches.
The Navitimer was within +3 seconds compared with the atomic watch. Surprisingly the mechanical Seamaster is behind a minute
The 50th Anniversary and the Seamaster automatic are pretty much on time -even to the seconds- compared to the Navitimer
I only compared those 4 because inly could press 4 crowns at the time! Haha
