12-HOUR GMT COUNTER

BA111OD redefines the travel complication with its 12-hour GMT counter, designed for intuitive, highly legible tracking of a second time zone. Unlike conventional GMT hands, this dedicated counter ensures effortless reading and even supports offset zones such as 30-minute (India IST, UTC+5:30; Newfoundland NST, UTC-3:30) and 15-minute (Nepal NPT, UTC+5:45; Chatham Islands CHAST, UTC+12:45), making it a truly global approach to timekeeping.
