If you find that your diver's watch is malfunctioning, do not attempt to repair it but immediately send it to SEIKO CUSTOMER SERVICE CENTER. n TEMPERATURES The key components in mechanical watches are made of metals, which expand or contract depending on temperatures due to metal properties. This exerts an effect on the accuracy of the watches. Mechanical watches tend to loss time at high temperatures while they tend to gain time at low temperatures. n MAGNETISM n CHEMICALS n PERIODIC CHECK NS Your watch will be adversely affected by strong magnetism. Keep it away from close contact with magnetic objects. 2 - 3 Years Be careful not to expose the watch to solvents, mercury, cosmetic spray, detergents, adhesives or paints.
