Seiko 55 fathoms snzh55 snzh55k1 snzh55j1

The Seiko SNZH55, often nicknamed the "55 Fathoms," is a stylish and reliable automatic dive watch featuring a 42mm stainless steel case, a black dial, and a unidirectional rotating bezel. Powered by Seiko's 7S36 automatic movement with a 41-hour power reserve, it offers a water resistance of 100 meters, making it suitable for swimming and snorkeling. Popular for its versatility, the watch is frequently modified by enthusiasts to resemble the Blancpain Fifty Fathoms, enhancing its appeal. The SNZH55 is available in two variants: the SNZH55K1, manufactured outside Japan, and the SNZH55J1, made in Japan, with minimal differences between them aside from the manufacturing location and minor dial text variations. Durable, affordable, and mod-friendly, the SNZH55 is a favorite among watch collectors and dive watch enthusiasts.
