Known as the Chariot Tank, it features an elegant design following the classic style of “tank” models, with a rectangular stainless steel case measuring approximately 27 × 35 mm and a minimalist blue sunburst dial with Roman numerals.

Equipped with the 2220 caliber, a high-frequency manual movement (28,800 vibrations per hour), known as “Hi Beat.” It offers only hours and minutes functions, reinforcing the clean and sophisticated aesthetics of the model.

A combination of visual refinement and rarity, since it was produced for a limited period, approximately between 1973 and 1978, making it an elegant and discreet choice for those who appreciate Seiko’s watchmaking tradition and the charm of high-frequency manual watches.
