Precision of movement

  • Entretien montre ref 1652420
The precision of watch models with mechanical movements is determined by the balance. This oscillates at a rate of 21,600 or 28,800 vibrations per hour depending on the model. Despite all the care that the master watchmakers of the Jaeger-LeCoultre Manufacture have lavished on building and assembling your watch, its accuracy is subject to the influence of gravity, magnetic fields, impacts and ageing of the oils. The precision of a watch is measured by its regularity of rate in various positions. Your individual temperament and your activities could be the cause of slight irregularities. If you observe a discrepancy in the running of your watch, we advise you to entrust it to an authorised Jaeger-LeCoultre retailer who will make the necessary adjustments.
