Seiko's Prospex collection is dedicated to creating sporty, precise and reliable watches. The Prospex SPB453J1 automatic watch is made entirely of stainless steel with an anti-scratch coating. Water-resistant to 300 meters, it is the perfect representation of Seiko's expertise in diving watches. Its attractive green dial features Lumibrite-coated hands and hour-markers, a domed sapphire crystal with anti-reflective coating and a green unidirectional rotating bezel.
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 redux, 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 ‘cove’ black bezel and matching dial. 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.
