Sealane OS-22 Chronograph – (Chronographenfunktion defekt) High Performance Japan Chronograph

Robust Japanese chronograph from the Sealane brand, manufactured by the Japanese company Sun Flame Co., Ltd. – known for high-quality sports watches with professional specifications.
The Sealane OS-22 combines the design of classic pilot's and marine service watches with modern technology and excellent workmanship.

The deep brown-black dial with its fine sunburst finish, large Arabic numerals, and tachymeter scale ensures excellent legibility. Three subdials for seconds, minutes, and hours, along with the distinctive knurled bezel, lend the watch a technical, masculine character.
The solid stainless steel case with screwed-on base and the water resistance up to 20 bar (200 m) underline the functional requirements of this model.

Inside, the tried and tested Miyota caliber OS22 is at work, a precise Japanese quartz chronograph movement with 12-hour measurement, date and quick reset.
