Seiko World Time 6217-7000
This watch was made in a limited edition to commemorate the 1964 Tokyo Olympics. The watch allows you to denote the time in all the major cities around the world.
The case is solid stainless steel with crown at the 4 position ( the crown on this model is NOT the original Seiko crown for this model. The case-back features the Olympic torch and is signed Seiko. The dial which is in amazing condition has all the worlds major cities on an inner moving bezel around an inner 24 hour chapter ring. The hands are silver with a black 24 hand. The date aperture is at 3 o clock. The watch sits on a quality stainless steel mesh bracelet, this can be changed to a leather strap if required. The automatic movement is incredible quality made by Seiko.
It’s an automatic watch and the inner bezel (with all the city names) rotates around by turning the crown; the idea is that you set the time so the little black arrow hand points to the time on the 24h scale
If you then rotate the bezel so black arrow points to the place you are in the world at the time, you can then see what time it is everywhere else in the world
The World Time was released in 1964 to celebrate the Tokyo Olympics, and the case back has a flaming torch etched or stamped on it in reference. There’s a bit more detail on World Times (or World Timers as they’re sometimes known) here, here and here.
I think this particular watch (reference 6217-7000) was produced in June 1967
