One of the not so popular divers in the Seiko JDM lineup is the Shogun, with the 6R15 caliber.
However I find the look of the Shogun more conventional - crown at 3 o'clock, chrome lined indices and a matt finish from the Diashield coated Titanium (supposedly increasing the scratch resistance of Titanium). The Shogun has drilled through lug holes, making it very easy to change straps. But I think what irks collectors most is the "monster-styled" hour and minute hands. The second-hand looks presentable though.
With a internet price of nearly twice the price of the steel Sumo, it is no wonder the Shogun is fading away.
Here is the same watch in different dial variation:
Can the Shogun last through 2012-2013 on Seiko's lineup? We shall see.
