The Spring Drive Marine Master

SBDB011 - The Ultimate Dive Watch

Seiko is well known for creating some of the best dive watches around.  When they released the Prospex line of watches Seiko took it as a challange to become the best if not one of the best Dive watches around.  Then you have the ultimate version of the Prospex, the Marine Master.  The SBDB011 has all you could want in a dive watch.  Unique styling done in a way to still pay homage to traditional dive watches.  The toothy bezel of the SBDB011 is easy to grip, even when wearing gloves.  The case and bracelet are made of titanium, so even though it is a larger watch it has a nice light-weight feel.  The movement is a arguably the most advanced in production movement, the Spring Drive.  

We currently do not have this watch in Stock.

Drive, Spring Drive

The most interesting part about this watch is the powerhouse movement that this transocean has inside.  It has the fabled Seiko Spring Drive movement.  The movement that is a unique movement to itself.  It is the movement that powers the luxury watches, Grand Seiko.  So, you have a dive watch with this amazing movement.  You are getting an amazing watch movement for a fraction of the cost of a Grand Seiko.  The Spring Drive movement causes a second hand glides across the dial.  It is both hypnotic and beautiful.  

What is so Special about the Spring Drive?

The Spring Drive idea came to a Seiko engineer in the 1970s.  It took over 20 years of testing to create the spring drive movement.  It is not a mechanical watch and it is not a quartz watch, it is it's own unique concept.  The Spring Drive uses a Tri-synchro regulator instead of an escapement system like mechanical watches.  The Spring Drive uses mechanical, electrical and magnetic energy to work.  The brilliance of the Spring Drive system is something that needs it's own blog post to discuss.
