The Seiko Prospex 1965 Heritage Automatic GMT Diver's Ref. SPB509J1

celebrates the 60th anniversary of the legendary Seiko diver's watch from 1965 – the model that laid the foundation for Seiko's ongoing success story in the field of professional diver's watches. The limited edition of 6,000 pieces combines the classic design of the historic predecessor with modern technology, an additional GMT function, and the robustness of the current Prospex collection. This makes it equally suitable for divers, frequent travelers, and collectors.

The 42 mm stainless steel case offers balanced proportions and high durability. The screwed crown and screwed case back, together with water resistance up to 30 ATM, ensure professional diver's watch qualities. The unidirectional rotating bezel allows safe measurement of dive times, while the scratch-resistant sapphire crystal protects the blue dial. Luminous hands and indices ensure excellent readability – both underwater and in low light conditions. The stainless steel bracelet with folding clasp completes the sporty overall impression.

Inside, the automatic caliber 6R54 operates with aPower reserve of approximately 72 hours. In addition to hours, minutes, seconds, and date, the watch features a 24-hour GMT hand to display a second time zone, making it a practical companion for travel.
