Seiko's original Diver's Watch with a slew of new upgrades

In the years since it released its first diver’s watch in 1965, Seiko has developed new technologies, features, and designs that have won the favor of professional and recreational divers the world over. Through more than a half-century of innovation, the company has continuously pushed back the boundaries of where sports watches, and diver’s watches in particular, can go and how they can be used. Continuous enhancements in safety, reliability, legibility, and ease of use have made Seiko a leader in diver’s watches. As Seiko celebrates the 100th anniversary of the wordmark "SEIKO" appearing on a watch dial, the venerable Japanese maker has introduced a slew of upgrades to its most sought-after modern re-interpretation of the original diver's watch from 1965, now upgraded with 300 meters of water resistance and a power reserve of three days.

This watch is now powered by one of Seiko’s latest in-house automatic movements, Caliber 6R55, which has a power reserve of 72 hours. This watch is further enhanced to ensure water resistance to 300 meters, a first for Prospex non-saturation diver’s watches. The date window has been moved to the space between four and five o’clock to allow for a more symmetrical design and for the 3H space to be filled with Lumibrite, ensuring high legibility even in dark conditions.

Also updated is the physical case dimensions, now with a case diameter of 40.0mm, a lug-to-lug length of 46.4mm, and a thickness of 13.0mm, yielding an easy wearing experience perfect for everyday use. A new bracelet with shorter links and a smaller clasp allows the watch to conform to the wearer's wrist and provides a new level of comfort, while the case's shorter lugs also ensure a high degree of wearability.
