Seiko Prospex 1965 Heritage Diver's Watch in Tide Grey

This piece is a re-interpretation of Japan's and Seiko's first ever Diver's watch, released in 1965. This design is a special edition commemorating 100 years of Seiko featuring on a watch dial - the brand name now synonymous with watchmaking innovation.

The original automatic 1965 Diver's watch marked the beginning of Seiko's watchmaking pursuit for diving reliability, safety, and professional specifications. From 1966-1969, this watch was worn by members of the Japanese Antarctic Research Expedition on trips to the South Pole, proving its durability in challenging environments.

For this latest revival, the design is updated with a more sophisticated specification, heightened water resistance, and improved power reserve. Built in a 40mm stainless steel case, the sapphire crystal glass is surrounded by a deep "tide" grey bezel and matching dial, closely resembling the 1965 original. Gold coloured accents further enhance its vintage style. In line with professional ISO Diving specification, the hands and indices are coated in glow-in-the-dark Lumibrite whilst its upright date calendar in a 4.5 o'clock position also add to its legibility. For extra comfort and wearability, the bracelet has updated short pitch links and a shorter buckle. It is also slimmer than previous models, with a 13mm depth.

The in-house built 6R55 automatic movement is accurate to -15/+25 seconds per day with a 72-hour power reserve and 300m water resistance.

This special edition piece is accompanied by an eco-friendly fabric "Seichu" strap, made of 100% recycled plastic bottles.
Seichu is a Japanese braiding technique seen in a traditional "obijime", the decorative cord that holds a Kimono sash in its place.

Prospex is a combination of the words "Professional" and "Specifications". Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
