Parkbury's View: A real JDM gem! The highly legible dial and a workhorse of a movement make this an everyday sports watch. A Japanese masterpiece!
Dunn's Assessment: This is one of my most favorite watches. I have one in my personal collection and find it on my wrist very frequently. The Marine Master series has been very popular but discontinued by Seiko in 2018, so i won't be selling mine anytime soon!
Story behind the watch: If you love anything that is JDM (products available for the Japanese Domestic Market only) then you would have to know about the SBDX001. The Marine Master series of watches started all the way in 2001 with the MM300 (SBDX001) and has been evolving ever since. It has been one of the most popular "high end" dive watches by Seiko for many years and continues on today. Being the best watches in their PROSPEX (Professional Specifications) series of divers, the MM series is highly capable and is loved by enthusiasts. The caliber is Seiko's 8L35, which is based upon the highly reliable GrandSeiko caliber 9s55, but without all the finishing. It is nearly impossible to find one of these in this NOS (New, old stock) condition. Ours comes with a luxurious custom handmade "African Goat" leather strap with lime-green inner lining. For true JDM junkies only!

Features: JDM / 300m water resistance / rotatable bezel
