Seiko Quartz “Chronos” – Ref. 7433-5010 • Caliber 7433 (September 1986)

This elegant Seiko Chronos watch dates from September 1986 , clearly datable by its serial number 69xxxxx (6 = 1986, 9 = September). Reference 7433-5010 belongs to Seiko's premium quartz line of the 1980s, characterized by high-quality, understated designs and highly precise quartz movements.

The model features a white, finely textured "Tapestry" dial , slim applied hour markers, a rectangular date window, and polished dauphine hands. The angular, octagonal case shape is typical of Seiko's design phase in the mid-1980s, which marked the transition from the angular design of the late 1970s to more elegant lines.
