Horological Meandering

These world time keepers explained:

- The Luxor is a fully fuctioning worldtimer, the hour disc rotates once every 24 hours while the hour hand takes twelve for a full rotation. It is set by placing the hour hand on the triangle at the desired city. Since this clock was made Singapore has gone +1, odly Calcutta and Bombay are one hour apart eventho they are on the same time since 1948.

- The Breitling is the most complete af the lot, DST accounted for, when the time zone of choice is moved to 12 the hour hand moves accordingly. The date changes both when traveling East or West.

- The Seiko is automatic only (not hand wound). You need to manually place your timezone at the 24 hour hand to check times in other time zones. This is done through the crown at 4. The date only jumps ahead.

- The Luxor is just a handwound clock with a bunch of cities on the outer ring. You need to turn the disc manually and place your city on your time on the 24 hour ring to check other time zones.

- The Raketa works like the Luxor. All time zones between Geneva going East to Samoa are Soviet Union era time zones. An ideal watch for Trans Siberia Express travel! The date only moves forward and has a quick set by pulling the crown to its extremity. The date jumps on every pull.

- The IWC Pilot Worldtimer has a fixed city ring and jumping hour hand and accounts for DST. The three dates window and Date Line marking make it easy to determine the date in other timezones. The IWC caliber 30750 is also used by Baume & Mercier in the Capeland Worldtimer.
