Seiko SBCW027 Landmaster Sagarmatha L.E 

It's a very hard process to open the watch from the top, you need to remove the bezel first. I would recommend you send it to Seiko

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

@@georgefl74 Thanks for the reply I will have to keep my eyes open for one. I know what it's like to hunt for elusive watches. 😂

Setting up watchrecon and ebay alerts helps. I'd recomment the terms 'Sagarmatha', 'SBCW027' (this L.E here), 'SBCW021' (first Sagarmatha), 'SBDW003' (second Sagarmatha). Cheers!
