Watch 12/24-Hour Time Converter – Dial & GMT Friendly
Convert either way for normal dials, military time, and 24-hour GMT hands—no AM/PM confusion.
Watch-setting tips
- Normal hour hand uses a 12-hour dial — AM/PM is not written on most watches
- GMT / 24-hour hand points to 0–24 scale (bezel or dial ring)
- 13:00 = 1:00 PM · 00:00 = 12:00 AM (midnight) · 12:00 = 12:00 PM (noon)
- When setting a GMT hand, convert local or home time to 24h first, then point the hand
Military time is 24-hour time, often written without a colon (1830 = 18:30).
If your GMT watch tracks home time on the 24h hand, convert the home zone—not the local zone—when you travel.
