Navigator Timer

The Seiko Navigator Timer is a cult favorite among vintage Seiko collectors, introduced in the late 1960s as Seiko’s answer to the growing demand for practical GMT watches. Designed for travelers and pilots, its standout feature is the independently adjustable 24-hour hand, allowing quick tracking of a second time zone. The Navigator Timer occupies a unique spot in Seiko’s lineup, bridging the gap between the brand’s early divers and the later, more elaborate GMT models.

The most sought-after references are the 6117-8000 and 6117-8001, both powered by the reliable Caliber 6117 automatic movement. These models feature a 41mm cushion case, bidirectional rotating 24-hour bezel, and a date complication. Variants differ in details like dial color, bezel font, and caseback engravings, with early examples and those retaining original bracelets or "proof" dials fetching higher prices. Patina is common, especially on the lume and bezel, and well-preserved examples are valued accordingly.

When considering a Navigator Timer, inspect the condition of the bezel and the crispness of the case lines—polishing is common and can reduce collector value. The 6117 movement is robust and parts are still available, making servicing straightforward compared to other vintage GMTs. Originality is key: replacement bezels and aftermarket hands are prevalent, so prioritize examples with correct, period components for the best long-term value and enjoyment.
