Many years ago I was an avid scuba diver. I've always preferred the heavier,more robust divers style that survives an active lifestyle.  I really enjoyed owning a Rolex Sea Dweller but had to sell it.  I dived with a Chronosport for almost 20 years then bought this Seiko model. Well, it's the best!  The luminus dial is easy to read at night and the stainless bracelet is very secure. It tells  accurate time, unlike the Rolex, cost zero for maintenance, unlike the Rolex, never needs batteries, unlike the Chronosport...and looks just as good as the Rolex. Looking for a sharp looking and rugged watch that tells accurate time, this Seiko is it!
