Longines uppger även följande:
INTELLIGENCE
Perpetual calendar on all versions. Calendar position detection. The shock detector detects shock and holds the hand back during the shock. The GPD system helps correctly reposition the hands after shocks (if they are very strong and the shock detector was unable to hold the hands back) or after exposure to magnetic fields. Increase in unbalances. Smart crown (includes a push function to activate time setting and other functions).Time zone change (hour movement) without losing the second. Very high accuracy in time setting to the second.

DISPLAY
Hours, minutes seconds in the middle. Date window. Perpetual Calendar. EOL indicator (preventively signals the end of battery life).

AVANTAGES
No more date correction needed. The watch autocorrects itself in case of shock or after exposure to magnetic fields to maintain its display accuracy. Manipulations are simplified thanks to the smart crown.

Obs! Notera att efter ett batteribyte har jag ej lyckats ställa in rätt datum. Klockan visar datumet förskjutet med två dagar.
