The following terms and conditions of the Jaeger-LeCoultre International Guarantee apply to Atmos® clocks sold or presented for guarantee repairs in all countries except the United States of America and Canada (for those two countries, see the Limited Warranty). Your Jaeger-LeCoultre Atmos® clock is guaranteed against all manufacturing defects for three years from the date of purchase, subject to the following conditions. Any part found by our technical services to be defective as a result of a manufacturing defect will, at the sole discretion of Jaeger-LeCoultre, be repaired or replaced free of charge. The Jaeger-LeCoultre International Guarantee is valid only if the guarantee certificate enclosed with this booklet has been duly completed, dated, stamped and signed by the authorised Jaeger-LeCoultre retailer who sold your Atmos® clock. This International Guarantee does not cover defects resulting from accidents, mishandling, incorrect or abusive use (for example, knocks, dents, crushing, excessive temperatures, powerful magnetic fields), unauthorised alteration or repair or the consequences of normal wear and ageing. The Atmos® clock operates without batteries, electricity or winding. It is accurate and silent but very sensitive, as it requires only an extremely low amount of energy to operate. To ensure that your Atmos® clock functions properly, you must place it on an absolutely stable horizontal surface (chest of drawers, console table, mantelpiece, etc.). We advise you to keep your Atmos® clock away from any magnetic fields (computer, television, etc.), as these may interfere with its functioning. The Atmos® clock must not be moved once it has been started. Should you have to transport your Atmos® clock, do not forget to lock the balance beforehand (this operation must be carried out just as the balance stops and before it starts moving again in the opposite direction). In order to use your Atmos®clock correctly, please refer carefully to the attached instructions, in particular before starting the clock or transporting it.
