The innovative GEMORO WBT21 tester is the latest generation device of its kind since 1994, and the best solution for watch and jewelry professionals!

• Without opening an analog quartz watch, the GEMORO WBT21 can determine if the battery needs replacement or indicate if the watch requires service. Featuring a bright LED light and loud beep, with a slim design enabling use of the watch test function – without first removing the watch strap! The new pulse sensor is extra sensitive, enabling use when the watch is positioned either face up or down.

• The GEMORO WBT21 precisely tests Silver Oxide 1.55V, Alkaline 1.5V, and Lithium 3.0V batteries under the appropriate load conditions.

• The watch test feature is powered by a consumer-replaceable CR2430 battery (not included). The device has a smart battery-saving auto-off function that powers it down after 2 minutes of non-use. The GEMORO WBT21 comes with a full one-year warranty. Designed in the USA, it’s quality-made, CE approved, and Reese’s Law compliant.
