---------------------------------------------------------------------- Japanese-made automatic mechanical movement Manual winding function Hack function (stops the second hand) GMT Bidirectional rotating bezel (24 clicks) 20 ATM water resistance Screw-down crown See-through back Applied Index (Luminous Paint) Tri-fold push-type lock buckle The HYAKUICHI Mechanical GMT Diver's Watch Model 14 is a mechanical automatic GMT diver's watch equipped with a Japanese-made NH34A movement. The bi-directional rotating bezel serves as a 24-hour display dial, completing 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 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 used 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 appeal of a wristwatch.
