Seastar Navigator

The Tissot Seastar Navigator made its mark in the 1970s as Tissot’s answer to the golden age of automatic chronographs, blending Swiss engineering with a bold, sporty design. It’s notable for its cushion-shaped 40mm case and distinctive dial layouts, often with colorful accents and a racing-inspired aesthetic that sets it apart from more conservative contemporaries. Collectors value the Navigator for its connection to Tissot’s adventurous spirit and its use of early automatic chronograph technology.

Key reference numbers for the Seastar Navigator include the 40522 and 45502, both housing the Lemania-derived caliber 872 or caliber 1341 automatic chronograph movements. The main differences between variants are the dial configurations—some feature triple registers with date, others dual registers—and bezel types, with certain models offering a tachymeter scale. Water resistance is typically rated to 60 meters, making it suitable for light aquatic use but not a full dive watch.

Pricing varies based on originality and condition; full sets with original bracelets and unpolished cases command a premium. The Navigator’s value is strongly influenced by the presence of the correct movement and dial, as some examples have been subject to dial replacements or swapped parts over decades. Lume color, handsets, and bezel wear are important to check, as sourcing period-correct replacements can be challenging. This is a model where originality and completeness directly impact collectibility and future value.
