First of all I would like to thank Mr Koh from Kymwatchblog for entrusting me with this classy yet sporty watch. It's really rare and difficult to find one now as this JDM(Japanese Domestic Model) beauty has been discontinued since mid 1990s. This 40mm(w/o crown) watch is a homage to the Rolex Submariner with a water depth rating of 100m and a bi-directional bezel. It is equipped with the 7S26 movement not unlike the Monster. The SKX031J originally came on a vented rubber strap but I went to purchase an oyster bracelet to complete the 'sub' look. What I like about this watch is it's versatility, it would compliment you perfectly whether you are in shirt and pants or in t-shirt and shorts. Wear it to anywhere and everywhere and you would not feel out of place, it is like what they say... a timeless design.
