Seiko Prospex challenges every limit, with a collection of timepieces for sports lovers and adventure seekers whether in the water, in the sky or on land. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative technology has changed global standards. We are constantly striving to bring ever greater reliability and safety to both professional and recreational divers.
In the decades since it introduced Japan’s first diver’s watch, Seiko has created a wide range of diver’s watches that have won the favour of professionals and enthusiasts worldwide for their safety, reliability, and ease of use. One such model is the SPB143, introduced in 2020. With water resistance to 200m and a power reserve of 70 hours, this watch has received worldwide acclaim for its functionality and its vintage-style design inspired by Seiko’s original diver’s watch, the legendary 62MAS. Today, Seiko introduces into the Prospex collection a range of watches based on the fan-favourite SPB143 that feature multiple enhancements in technology, design, and construction. Black dial and blue dial versions join the main Prospex collection, while a commemorative special edition with gold-coloured accents celebrates the 100th anniversary of the Seiko brand.
Each watch is powered by one of Seiko’s latest in-house movements, Caliber 6R55, which has a power reserve that extends to 72 hours, or three full days. This marks the first time that Caliber 6R55 has appeared in the Prospex collection. The new watches are further enhanced to ensure water resistance to 300m, a first for the Prospex collection’s non-saturation diver’s watches. A change in the location of the date window from the three o’clock position to the space between four and five o’clock now allows a more symmetrical design and more space to be filled with Lumibrite, ensuring high legibility even in dark conditions.
Even with the many upgrades that enhance performance, each watch has been redesigned to be more compact, with a diameter of 40mm, lug-to-lug length of 46.4mm, and thickness of 13mm, while maintaining the reliability, safety, and ease of use required of a Seiko diver’s watch. Each watch features a stainless steel bezel with an aluminum insert for a slim design that delivers a classic feel and appearance, with minute markings that now extend under the numerals of the bezel display. The bezel’s minute markings and numerals are laser-engraved to prevent their wear from long periods of use. Thanks to a new bracelet with shorter links and a smaller clasp, the watch achieves a higher level of comfort as it conforms to the wearer’s wrist.
