This service is a very basic installation of a cell/battery in most quartz watches. This service includes a new, battery and a freshly sealed gasket around the case back. The case back is then properly tightened down or snapped back on. Pressure Testing is performed for dive watches per request and for an extra charge. Battery prices range from $15 for most standard quartz watches, $25-65 for Luxury brands and $75+ for specialized brands. The price reflects the delicate nature of the watch (mother of pearl dial, gold case, etc.), and the difficulty of the battery installation.
