A Transitional Model
Series 3

A Transitional Model
Model No: 6117-601X

In early in 1968 SEIKO started production of its Series 3 World Time watch. This model was manufactured from February 1968 through November 1969. That was the longest production run to date for the World Time.

SEIKO produced this series under two sub-model numbers, of otherwise identical watches. The 6117-6019 was intended for the North American Markets. The 6117-6010 was intended for the the Japanese Domestic Market and all other International Markets.

This watch received an updated movement (the 6117A), a new dial and handset, including new GMT hand, and an updated inner bezel. GMT is marked on the cities ring for the first time and Chicago is replaced with Mexico City as the Central Time Zone marker. This likely aligns with the 1968 Olympics, held in Mexico City, though no commemorative case back was produced.
