Seiko Marinemaster MM300 SBDX043 | JDM Limited Ed.

⭐ Seiko Prospex Marinemaster MM300 SBDX043 – the true Japanese Domestic Market (JDM) reference, purchased in Japan and limited to 3,000 pieces worldwide for Seiko's 140th Anniversary.

Unlike the export model designated SLA047, this is the original SBDX043 reference intended for the Japanese market. A modern collector's favourite, it combines the legendary MM300 platform with one of Seiko's most striking limited-edition designs.

Its textured forest green sunburst dial draws inspiration from the ancient mangrove forests of Iriomote Island, while the iconic monocoque case showcases Seiko's renowned Zaratsu polishing and exceptional finishing. Beneath it beats the hand-assembled 8L35 movement, built at the Shizuku-ishi Watch Studio to Grand Seiko mechanical standards.
