The alarm and backlight are both working fine. The lower left button is stuck and cannot be operated. There is no problem with setting the time. To prevent damage, the buckle of the belt will be removed before shipping. (See photos 12 and 13) It will be shipped via Yu-Packet Post Mini. Since this is an old watch, I cannot guarantee its operation after arrival. Please purchase it as a junk item. Please comment if you have any questions.
