★This product uses monitor batteries. This is the battery built into the watch you purchased, and is installed at the time of shipment from the factory to check the functions and performance of the watch. Since the battery will wear out during the period before the customer purchases the product, the lifespan of the monitor battery may be shorter than the lifespan specified in the instruction manual. Additionally, battery replacement will be charged even within the warranty period. ★
