Can extreme temperatures upset accuracy?
Heat and cold can affect the precision of both mechanical and quartz watches. Oscillation of the quartz oscillator varies according to temperature and this does affect the accuracy of the quartz watch very slightly. But this change is very small compared to the effect of temperature on mechanical watches where the consistency of the lubricant influences accuracy. What else determines accuracy? Consistency is the key with mechanical watches. Accurate time telling can be enhanced by winding the watch at a certain time every day, wearing the watch for a certain period every day and the way a watch is left lying when it is not on the wrist. Quartz watches are pretty trouble free temperature extremes are the only variable here. What is the life of a quartz watch battery? Watches are designed to use either silver oxide or lithium batteries. A silver oxide battery will last two-five years. Lithium batteries have a life of two-seven years depending on the use of the watch functions, for exampl
