It’s been confirmed that Seiko will be releasing three new and improved versions of the much loved SBDX017 Marine Master 300. It is unknown at this time if these will be JDM – Japanese Domestic Models only, or released world wide. The new versions will feature significant improvements including a ceramic bezel with lume and a sapphire crystal. The watches will be designated SLA02J1 (black), SLA023J1 (blue), and SLA027, which is a Zimbe special edition. They will reportedly sell for the same price as the current SLA019. (ωχ..

The monoblock case remains as does the 26 jewel – high beat 8L35 movement, oyster style bracelet with adjustable clasp for incremental size changes and the dial. Upgrades will include a flat sapphire crystal, new blend of lume, a ceramic bezel insert with lume (from 12 to 20 min marks only), and a controversial change in dial text. Gone is the “Marine Master” name, replaced by the “X” Prospex logo. The bezel itself is also slightly thicker, likely to allow for the new Sapphire crystal. There is also a blue version, SLA023J1, that will be released at the same time, with the same features.
