Reading the functions

The arrows next to the watch above allow you to show different time zones.

First time zone

The hands display the first time zone.

Second time zone

The adjustable time zone disk displays the second time zone. If the second time zone is ahead of yours (for example, +3 hours), you adjust the time zone disk until it displays this number at 12 o’clock. If the second time zone is behind yours, you subtract from 12, and set the result at 12 o’clock.

Overview

The two time zones watch uses an adjustable time zone disk to display two time zones on a single watch hand. A single glance will allow for simultaneous readings of two time zones. The moveable time zone disk can be quickly adjusted so that the difference between the time zones is displayed in the 12 o’clock aperture with the hour hand displaying both time zones.

Available models

Mechanics

How is the two time zones function executed?

Ludwig Oechslin replaces the 31 tooth date disk that comes on a ETA 2824-2 base movement with a 48 tooth user-adjustable time zone disk (pictured above right).

What was the motivation for the design?

Oechslin would like to read both the time and a second time zone with a single glance. His moveable time zone disk can be quickly adjusted so that the difference between the two time zones is displayed in the opening at 12 o’clock. The hour hand then displays the time in both time zones.
