Seiko Lassale Quartz Tank Watch, Ref. 1230-5289

Story

In 1981, Seiko acquired the prestigious Swiss brand Jean Lassale to merge European luxury design with Japanese quartz precision. At the time, the watch world was obsessed with 'thinness,' and Lassale was the undisputed king of slim movements.

Maker / Origin

Jean Lassale was a Swiss watchmaker who famously invented the world's thinnest mechanical movement before the brand was bought by Seiko.

Condition & Value

The case shows visible wear to the gold plating, particularly on the edges and corners, revealing the silver-toned base metal underneath. The crystal appears relatively clear, and the leather strap is a modern replacement. The plating wear reduces the value by roughly 40% compared to a mint-condition example.
