The two time zone due ore now comes in British racing green (Pantone 343C to be precise), encased in a 42mm sized grade 5 titanium case which is 10.4mm thick and water resistant to 100m.

The due ore uses an adjustable moving time zone disc to display two time zones using just a single hand. The indices display the primary time and the adjustable disc displays the second time zone.

This is done by setting x amount of hours ahead at 12 o’clock if your second time zone is ahead, or subtracting if the time is behind. So if the second time zone is +3 hours, the wearer moves the disc until ‘3’ is displayed at 12 o’clock. If the second time zone is behind the primary time zone, you subtract from 12 and that figure is set at 12 o’clock.

The difference between the zones is displayed in the 12 o’clock aperture with the hour hand pointing to both time zones – the second one being in the aperture associated with the reference time. In these photos, the primary time is 2:24 and the second time zone is +8 hours i.e. 10:24.

How is this done? Ludwig Oechslin replaced the 31 tooth date disc that comes on a ETA 2824-2 base movement with a 48 tooth time zone disc. It has the standard 28,800 VPH and power reserve of 38 hours.

On the Pantone 343C dial are markers and a seconds hand in Pantone 627C, and hour and minute hands in grey (Pantone 429C) with Super-LumiNova.

The new ochs und junior Due Ore British racing green comes on an Ecopell brown “Terra” leather strap with titanium buckle handmade by Sabina Brägger and in a leather pouch. Its RRP is CHF 3,230. You can order directly from them at oj@ochsundjunior.ch
