The Modern Willard SPB151 Seiko doesn't write a lot about it, heck they never reference the name Willard, but it is a very important watch in Seiko diving history.  Why they don't call it the Willard is understandable, it is probably an issue with the copyright, since the name comes from a major motion picture that really has nothing to do with Seiko.  The Willard is an important watch and if you read the literature all Seiko really says about it is that it is, "A much respected diver's watch."  How much of an anticlimactic statement it that?  No matter,...

The Green Dial of the SBDC059 I've heard people talk about this watch over and over again.  What is the reason behind all of this interest?  The green...

The SBDX013 - An Icon Wears Black The Seiko Tuna is one of the most iconic wristwatches today.  The tuna style watch took over 7 years to design.  They started this long design process in 1968 when a saturation diver complained that his Seiko watch couldn't take the abuse.  Seiko had just gotten into the dive market three years before.  The original Seiko Tuna was released in 1975 by a design team lead my Ikuo Tokunaga.  That watch had a lot going for it, so much so that Seiko was awarded 20 patents.  Later, in 1978, Seiko developed the first saturation...
