SEIKO released their first divers watch 1965, the 6217 aka 62MAS with 150m WR.
A few years later, 1967 SEIKO released the 6215, a divers watch with monoque case and 300m WR which was very good during that time. The watch had an automatic low beat 18000bph movement and was only in production for one year.
SEIKO, in their strive for perfection, released a new revolutionary divers watch 1968, the 6159-7000. It has a similar look to the 6215 but features a much more suitable movement, a Grand SEIKO hi-beat (36000bph) automatic movement with hack and wind functions. This movement improved the shock resistance and the timekeeping. The 6159-7000 was marketed as the first professional divers watch from SEIKO.
6159-7000 was available with count up or count down -bezel. Most of them sold with the count up bezel and it has been said that it was possible to switch the countdown bezel to a count up bezel free of charge when SEIKO serviced the watch. The 6159-7000 was only produced 1968.
The 7000 case was replaced by the 7001 case 1969 and the border on the back simulating a case back appeared with the 7001 in march 1969. The 6159-7001 was also only produced for one year (1969).

A fine and very rare stainless steel diver’s wristwatch with date and sweep center seconds.
