Setup, Compatibility & Care
To begin using your LONGINES Flagship, manually wind the crown 15 to 20 times to build an initial power reserve. Set the time by gently pulling out the crown to the last position and rotating it until the desired time is reached. When not in use, store the watch in a cool, dry place, ideally away from strong magnetic fields which can affect mechanical accuracy. For cleaning, use a soft, lint-free cloth to wipe the case and crystal; avoid submerging the watch in water or using harsh chemical cleaners. We recommend professional servicing every 4 to 5 years to ensure the movement remains lubricated and accurate.
