• Manufacture Jaeger-LeCoultre: la montre Chronomètre Geophysic
Magnetism is caused by frequent exposure of a watch to significant magnetic fields of various origins: (mobile phone, magnetic clasp on a handbag, glasses case or wallet, office gadgets, anti-rheumatic bracelets) In watches with mechanical movements, the balance-spring can be affected by such exposure. Magnetic fields can affect the precision of your watch. We recommend that you take your watch to one of our service centres or your authorised Jaeger-LeCoultre dealer.
