A brief review of the Landmaster Sagarmatha limited edition, made to commemorate the 1999 Ken Noguchi world record (at the time) climbing of the seven highest summits by age 25
The easiest to find is the SBDW005/SBCW001 red Landmaster, you can find my review in the channel. It was sold up to a couple of years ago, new. Very nice watch, titanium grey, deep red, carbon fibre dial.
I haven't ever seen one up for sale in the West. There were two non-limited versions, one of those occasionally surfaces for ~1200$ depending on condition and box/papers
