All watches are in good running order unless noted and come with a 90-day warranty as long as no abuse or water damage has occurred. This warranty is to cover the proper mechanical operation and functions of our watches, including reasonably good time keeping. Misuse and abuse includes dropping the watch, submerging the watch in any substance and more than usual wear and tear. If the watch has been found to be opened or tampered with, the mechanical warranty becomes null and void and the watch is not returnable nor will any refund be issued.
