The Spring Drive TransOcean

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.

The Transocean

The TransOcean is a relatively new style of hybrid watch for Seiko.  The series is only a few years old, but it has a dramatic look to it.  The transocean series is a mid-level Seiko product.  Much more expensive that your standard Seiko, but no were near the price of Grand Seiko.  It is really a treat to have the spring drive in this watch.

Titanium, the Cherry on Top

The first thing you notice when you see this watch is that amazing gliding second hand.  The thing you notice when you pick up this watch is that it is extremely light.  The watch might be a larger sized watch, around 45mm, but it is extremely light.  That is because the watch band and case is made up of titanium.  Beyond that you will find other delicious features from the Transocean series, the dia-shield coating and the zirconium ceramic bezel.  

We currently do not have the Marine Master SBDB017 in stock.
