Seiko Limited Edition Prospex Sea 1978 Re-Creation Tuna Case Quartz Divers Men’s Watch S23627J1

Seiko Limited Edition Prospex Sea 1978 Re-Creation Tuna Case Quartz Divers Men’s Watch S23627J1

This year is the 40th anniversary of the first production of Seiko’s first divers watch. In 1978, Seiko produced the world’s first Quartz saturation diver’s watch and in commemoration of the 40th anniversary the Japanese watchmakers have produced this highly limited model. Of which only 800 of the Seiko Prospect S23627J1 have been produced worldwide.

This masterpiece flaunts the world’s first two layer case construction, comprised of 49.9mm of titanium and a ceramic outer case. The benefit of the case being made out of titanium is that it remains highly durable whilst remaining lightweight and therefore practical for the wearer. Moreover, titanium is highly resistant to corrosion and despite it being lightweight titanium remains 40% stronger than steel.  This Prospex model also boasts an outer case made out Zirconia Ceramic, which is seven times harder than steel, and is even more resistant to corrosion than titanium.

This sleek and highly reinforced design allows the watch to lay claim to the mantel of being labelled the ‘ultimate divers tool’. This updated model is water resistant to 1000 metres deep and it is further supported by the design of the crown, which has screw-down protection to prevent it from being pulled out by any accidental operation. Greater security is achieved by positioning the screw-lock crown at the 4 o’clock position. This also further prevents the risk of water ingress whilst diving.

The watch features a black dial with luminous hands, making the display clear to the wearer whilst diving. With Seiko’s Lumi-Brite technology, the hour markers and hands remain visible in low light conditions for up to 8 hours from initial exposure to light. Also, the deep grooves in the bezel also make the watch more accessible to a diver, as it allows them to operate them whilst diving gloves are being worn.

The watch comes complete with a two year guarantee and is priced at £2,700. View the full specification, view the watch here.
