“The Marine Master“
Seiko SBDX 001
The Seiko Marine Master soon garnered a high reputation among Seiko dive watch enthusiasts, for many becoming the definitive Seiko dive watch.
The Marine Master is part of Seiko’s high end Professional Divers Series, those with water resistance above 200m developed for use in saturation diving.
Though a lot of people refer to the Seiko Professional Diver series as ‘Marine Masters’, the SBDX 001 is the genuine Marine Master, the only one with it written on the dial.
At 210 grams this is a hefty watch. One of the reasons for its weight is its one piece monocoque case design which increases water resistance. If weight is an issue this can be alleviated by changing the SS bracelet for the included rubber one.
The movement is the 8L35 with 26 Jewels and a 50 Hour Power reserve and accurate to within 10-15 seconds a month. This is the only seiko dive watch that uses this movement, which is also used in some Grand Seiko’s, it is also one of few that is individually hand assembled.
The crystal is domed Hardlex with anti-reflective coating.
