Tudor MT5602 Movement Precision Discussion

Key Points from the Discussion

• Before seeking service, consider how the watch is positioned when not worn, as different resting positions can influence timing results.
• A new watch may require a 'break-in' period of a couple of weeks for the movement to settle, after which its precision might improve.
• The 'crown right' position is often found to be the slowest for Rolex and Tudor movements, which can be used to mitigate daily gain.
• The author clarifies that his FXD MN24 is a brand new watch, recently acquired from an Authorized Dealer after being on a waiting list.
• Other Tudor owners report their watches, including Black Bay S&G and Pelagos LHD, are regulated to run slightly slow, typically -1 to -3 seconds per day.
• While +35 seconds over five days is not extreme, a deviation of +7 seconds per day for a COSC-certified movement is outside the specified range of -4 to +6 seconds.
