Seiko Updates the Classic Prospex Dive Watch for Its 100th Anniversary

The new editions of the Prospex from Seiko are a fusion of tradition and innovation.


Seiko’s lineage in watchmaking stretches back to 1881, but it was in 1924 that the brand truly made its mark with its inaugural wristwatch. Fast forward to 1965, Seiko made waves with the release of the 62MAS, marking its foray into the world of divers. Since then, the Prospex line has undergone transformations, with the 2017 SLA017 reissue capturing the essence of its iconic predecessor. Limited in edition size, the SLA017 left enthusiasts craving more until Seiko unveiled the SPB models in 2020, drawing inspiration from its predecessor. Now, the Prospex line has been revitalized for a new era, boasting specs that harken back to the beloved SLA017.

The latest iterations, available in blue (SPB451), black (SPB453), and charcoal (SPB455) variants, elevate the water resistance to 300m without sacrificing size, thanks to a redesigned caseback. Sporting a 40mm stainless steel case, these watches maintain the spirit of the original while incorporating modern comfort enhancements. Notably, the SPB455 pays homage to Seiko’s heritage with a textile strap crafted from recycled plastics, showcasing the brand’s commitment to sustainability. Updates such as a shifted date window and the new Caliber 6R55 automatic movement further solidify the Prospex SPB Dive Watches as must-have timepieces for enthusiasts. Priced from $1,300, these watches are a fusion of tradition and innovation, available for those seeking a blend of style and performance.
