・Purchased about 5 years ago and stored at home after being used a few times. It's in very good condition as it hasn't been used much. ・The bright color contrasts well with dark-colored tops, and the watch itself has a substantial presence, making it a great fashion accent. ・The battery is dead and has been left as is. As it is 20-bar water resistant, there's a risk of losing the water resistance if someone without sufficient knowledge replaces the battery, so I haven't had it replaced. ・I can consider replacing the battery if you wish, but in that case, I will add about 4000 yen to the price, and I will require you to purchase it once the operation is confirmed. ・Case and instruction manual are also included. https://www.casio.com/jp/watches/gshock/support.GA-100A-9A/ 20-bar water resistance World time: 48 cities worldwide (29 time zones, with summer time setting) + UTC (Coordinated Universal Time) time display, home time city swap function Stopwatch (1/1000 second, 100-hour timer, speed measurement function (MAX1998unit / h, 2unit / h unit), lap / split measurement switching) Timer (set unit: 1 minute, maximum set: 24 hours, measured in 1-second increments, auto-repeat) 5 time alarms (1 with snooze function) and hourly time signal Full auto-calendar 12/24 hour display switching LED light (auto light function, afterglow function, afterglow time switching (1.5 seconds / 3 seconds) Monthly difference: within ±15 seconds
