Grand Seiko presents its new spring-driven movement for the first time in the SLGA001 60th Anniversary Diver's Watch

I feel that Da Seiko just warmed up when it released its 60th anniversary last month, and the boy gently put it down. The anniversary continues, model SLGA001-a sturdy 600-meter titanium diving watch, equipped with a groundbreaking new 5-day Spring Drive movement, objectively speaking, it is superior to its predecessor in all aspects.

Before we get to know the new diving watch, it is worth noting that the 60th anniversary is considered to be a more important moment in Japanese culture, especially in the field of timekeeping. Of course, the 60th anniversary is the two most important of any watch. Key functions: seconds and minutes. But in a more esoteric sense, 60 is also the divisor of the adjustment speed of almost all mechanical watches: 36,000bph (60 x 600), 28,800 (60 x 480) and 21,600bph (60 x 350). It is worth repeating that since most of the 60th Anniversary Editions we have seen so far are limited in some capacity, this is by no means the last film Grand Seiko will provide for its fans in 2020.

If this particular reference seems familiar – it should. It is very similar to the backbone of the Grand Seiko sports series: reference number SBGH255, which has long been powered by the Hi-Beat automatic movement (please refer to it manually here). I say "similar" because thanks to the new Spring Drive movement 9RA5, the ratio has increased, so the height of this new diver is 16mm thinner, but it is still 46.9mm (come on, let's name it : This is a 47mm diver) titanium case.
