New Release: Seiko Diver Trilogy for 55th Anniversary

Seiko diver trilogy 55th anniversary

If Seiko is known for anything, it is known for its supremely good dive watches. Celebrating the 55th anniversary of its first dive watch, the 62MAS, welcome to the Seiko Diver Trilogy which includes the original 62MAS, the stunning 6215 high-beat and the iconic 6159 ‘Tuna’.

Despite being a relative latecomer to the world of dive watches — over a decade later than the first Swiss dive watches — it has developed a reputation for making some of the very finest examples on the market. Across their history, however, a trilogy diver watches have been selected by Seiko to remake (well, almost) to mark this anniversary: the 62MAS, the 6215 and the 6159. However, there is more here than first meets the eye with new materials and innovations present.

Across all three watches, the most obvious shared point is the presence of a dark, almost petroleum-blue dial. This subtle touch gives a delightful reference to the limited nature of these editions without compromising the style of each piece. More importantly, all steel case components across this Seiko diver trilogy are made from Seiko’s new ‘Ever-Brilliant Steel’. This form of steel delivers corrosion resistance far greater than that of normal 316L stainless steel. Whilst this is superb for marine applications, it also gives the watch a more silvery appearance to benefit those more interested in aesthetics.

First launched in 1965, the 150-metre water resistant Seiko 62MAS was rather far behind the work of Swiss competitors. It had an unguarded crown, slim hands and a lower water resistance. However, it started one of the most compelling stories in the watch industry and is indisputably beautiful.

The remake here takes its build from the remake of the 62MAS launched in 2017. In this way, it keep the enlarged 39.9mm diameter and 14.7mm thickness as well as the enhanced 200 metre water resistance. As a modern watch, these specifications are absolutely spot-on as, realistically, the original 38mm would have been less widely popular.

Limited to 1,100 pieces, this first watch in the Seiko diver trilogy uses a very premium 8L55 calibre which delivers a high-beat beatrate of 36,000 vph and a 55-hour power reserve. Aside from the stunning domed crystal and unique polished bezel, the use of a new form of steel and the dial colour will make this a hit.

The 1968 Seiko 6215 was the beginning of Seiko’s move to producing professional dive watches but also defined the case style for which modern luxury Seiko divers are known and praised. Its design increased water resistance to 300 metres through the use of a monobloc case and widened the bezel for legibility.

The modern remake replicates the original watch’s need for all servicing to be conducted through the front of the watch and retains the proportions. In many ways, this is the most faithful remake of this Seiko diver trilogy yet also uses the new form of steel and the blue dial.

A detail which is subtle but stunning is the removal of all gold elements from the hands and markers, thus giving a modern, subdued twist to the design. Furthermore, the bezel remains the stunning lacquered steel bezel as seen on the 62MAS remake as well as the 2018 remake of the 6215. In keeping with that 2018 remake, this watch is given the same 8L55 movement as that watch. It will be offered in 1,100 pieces.

Following a complaint from a Japanese saturation diver in the late 1960s after his watch exploded upon decompression, Seiko embarked upon a project to develop a watch impervious to the dangers of the world of professional saturation diving. In the same vein to the Omega PloProf, Seiko decided to simply prevent the ingress of any gases into the case yet did so in titanium — something which Omega was unable to achieve.

This 600 metre dive watch can be distinguished from later Seiko ‘Tuna’ dive watches by its enlarged shroud which covers the lugs completely. This design has been faultlessly recreated on this edition of the watch and, like the original, the case is titanium whilst the shroud is ceramic for scratch resistance. Interestingly, Seiko has chosen to produce the bezel from their new form of stainless steel in order to take the brunt of abuse from the front of the watch.

The dial also uses the blue colour seen across the range but mutes it with a matte, technical finish. To top this off, red text shows that this watch is anti-magnetic to 40,000 A/m thanks to an iron dial — roughly 500 Gauss. Inside this watch’s rather misleadingly 1000-metre water resistant case, the movement selected is the 8L35 as seen in the popular Marinemaster 300. This movement shares a similar architecture with the movement in the other two editions but has a beat rate of 28,800 vph and a power reserve of 50 hours. Of the three, this is definitely my favourite.
