Hyakuichi Model 14 Mechanical GMT World Time Watch with Japanese Aqua X Hacking Function [HYAKUICHI 101] Movement, Black,

Japanese-made automatic mechanical movement Manual winding function Hacking function (stops the second hand) GMT Bidirectional rotating bezel (24 clicks) 20 ATM water resistance Screw-down crown See-through back Tri-fold push-type lock buckle The HYAKUICHI Mechanical GMT Diver's Watch No. 14 is a mechanical automatic GMT diver's watch equipped with the Japanese-made NH34A movement. The bi-directional rotating bezel serves as the 24-hour display dial and completes a full rotation in 24 clicks. The NH34A moves in 6 steps per second, has a hacking function, and the second hand can be stopped by pulling out the crown, allowing for time setting to the second. The SEIKO catalog value states a daily variation of -20 to +40 seconds, indicating its high accuracy, but in reality, you will likely experience even greater accuracy than the catalog value. The GMT hand completes a full rotation in 24 hours, so it can be as a 24-hour counter or as a second time zone to indicate the time of any country. Like other HYAKUICHI diver's models, it uses a case that enables 200m water resistance, and features a screw-down crown and a see-through case back, allowing you to fully appreciate the charm of a wristwatch.
