The HAMAYOTA GMT Automatic Watch is a diver-inspired mechanical wristwatch designed with a sporty and functional GMT layout. Featuring a bold “Pepsi” style rotating ceramic bezel and a 24-hour GMT hand, it delivers a strong visual presence combined with practical dual time zone functionality.
Powered by a mechanical automatic movement with manual winding capability, the watch operates through wrist motion or crown winding, offering reliable everyday performance. The GMT function allows the wearer to track a second time zone using the independent 24-hour hand, making it suitable for travel and international use.
The watch features a stainless steel case with high corrosion resistance and a sapphire crystal for improved durability and scratch resistance. The unidirectional rotating bezel enhances its diver-style functionality, while luminous indices ensure readability in low-light conditions.
With 20 ATM water resistance, the watch is suitable for swimming and general water activities, adding versatility to its rugged design. The screw-down crown and solid construction further enhance its durability for daily wear.
