POWER RESERVE

Most Blancpain self-winding watches have a power reserve of between 40 and 288 hours. This implies wearing a watch throughout the day in normal conditions of activity. If the movement has come to a halt, it is advisable to wind it manually by at least 40 turns of the crown. This operation serves to supply the watch with the minimum power reserve required before replacing it on the wrist. Models with a calendar, which changes around midnight, must have at least 20 hours’ power reserve in order to drive the entire mechanism. Otherwise, the watch is liable to stop at around midnight.

WATER RESISTANCE

Most Blancpain models are water-resistant, apart from the minute repeater. This water resistance is necessary to protect the movement from dust and damp. While it is possible to swim with a water-resistant watch, the water-resistance guarantee does not exceed two years. Beyond this period, the water resistance may be compromised, leading to costly repairs. We therefore strongly recommend that you have your watch checked once a year by an authorised Blancpain watchmaker. Watches equipped with screw-locking crowns, pushers and case-backs guarantee perfect watertightness to 100 metres. For any further information regarding the crowns and pushers, kindly refer to the operating instructions for your model.
