Look up world timer bezel cities, old dial names, and hour difference from your home city.
If home is London (UTC+0) and the city is Tokyo (UTC+9), Tokyo is 9 hours ahead. On a world-timer, read the hour aligned with Tokyo on the city ring. Check DST when relevant. Historical names like Bombay or Saigon still appear on older dials.
Many bezels use a mix of modern and historical names. This table helps decode older dials.
| Dial name | Modern reference | Standard offset |
|---|---|---|
| Bombay | Mumbai / Delhi zone | UTC+5.5 |
| Saigon | Ho Chi Minh City / Bangkok zone | UTC+7 |
| Peking | Beijing | UTC+8 |
| Calcutta | Kolkata | UTC+5.5 |
| Rangoon | Yangon | UTC+6.5 |
| Christchurch | Auckland zone | UTC+12 |
1. Set local home time on the main hands.
2. Find the destination city on the 24-city ring.
3. Read the hour shown next to that city.
4. Use the day/night disc or 24-hour scale if fitted.
5. Adjust mentally for daylight saving when needed.
This is an educational reference for watch owners. Fixed bezels cannot track every political time-zone change. Always confirm critical travel times with a current official source.

How do I read a world timer watch?Set local time, then read the hour beside each city on the ring.
Why does my world timer say Bombay or Saigon?Those are historical dial names still used on older or classic world-time designs.
Does daylight saving affect a world timer?Yes. A fixed ring may need a one-hour mental correction during DST.
What is the difference between GMT and world timer?GMT usually tracks one extra zone; world timer shows a full 24-city reference.
