SEIKO Prospex 55th Anniversary DIVER’S Limited Editions [the HOLY TRINITY]

Seiko fans, prepare yourselves for a religious experience – this is the second coming, not of Christ, not the Holy Trinity (as such), but a holy trinity of sorts and there is a resurrection involved.



For the Seiko diver’s devotees, Seiko Prospex (who is not one to miss an opportunity to celebrate with an historic re-edition) has resurrected three important divers from the 60s and 70s.



The first model dates back to 1965 when Seiko introduced the first ever Japanese made diver’s watch, the 62MAS.



Equipped with an automatic movement and a water-resistance to 150m, it was put to use by the members of the Japanese Antarctic Research Expedition from 1966 to 1969.



From 1965 to 1975 Seiko created several popular divers, however there were three standout models,
these important landmarks from Seiko's first decade as a world-class dive-watchmaker have been re-created for 2020.

Celebrating Prospex’s 55th Anniversary, they are offered individually or in one epic triple boxset.



While the designs of each of three models remain faithful to the historic models that they are based on, they have very much up-to-date specs. that make use of ultra-modern materials.



Besides the use of Titanium or the Zirconia Ceramic that replaces a once plastic shroud, Seiko are most proud of their advanced grade of Stainless steel used in the construction of all three.



Known as Seiko Ever-Brilliant Steel (owing to its brilliant white tone), this grade of steel is more corrosion-resistant than any steel used in most high-end watches, today.



A watch industry first, it has been used for the cases of the 1965 and 1968 re-creations as well as the bezel of the 1975 re-creation whose case is Titanium, like the OG model.



This Stainless steel has a PREN (Pitting Resistance Equivalent Number) value 1.7 times higher than that of the grade of steel used in most high-end watches. PREN is a widely accepted standard used to measure corrosion-resistance.



This type of steel is used extensively in the surfaces, linings, bolts and other components of marine structures and vessels so as to avoid corrosion in a chloride-rich environment such as seawater.



In addition to the new materials there are also special movements for the trilogy. The 1965 and 68 re-creations are powered by the high beat 8L55 movement while the 1975 re-creation has a Caliber 8L35.



Both movements were developed and assembled specifically for diver's watches at the Shizukuishi Watch Studio.



All three models have Sapphire crystals with anti-reflective coating on the inside. The 1975 re-creation has an increased anti-magnetic resistance of 40,000 a/m thanks to its dial which is made of pure iron.



The trilogy will be rolled out this of 2020 with SLA037J1 (65) released in June, SLA039J1 (68) in July and SLA041J1 (75) in August.



However Prospex’s answer to the Arch of the Covenant, the Prospex Diver’s 55th Anniversary Limited Editions Special Commemorative Box will be available from May 2020.

The special commemorative box will have all three re-creations inside with additional black straps. Just 100 sets will be released.
