Seiko Mod 'Batman' GMT Marine Master Tribute

This is a custom-built 'Seiko Mod' wristwatch, designed to replicate the aesthetic of a professional GMT diver. The watch features a black PVD-coated stainless steel case approximately 40-42mm in diameter. It is equipped with a 'Batman' style ceramic bezel insert, characterized by a split blue and black 24-hour scale. The dial is a deep sunburst blue, bearing the 'Seiko' logo and 'Marine Master Professional' text, though this is likely an aftermarket part rather than an original factory dial. Notable features include round luminescent hour markers, a date window at the 3 o'clock position with a magnifying cyclops, and a four-hand configuration including a GMT hand. The watch is mounted on a vintage-style black leather strap with white contrast stitching near the lugs. The condition appears to be excellent with no visible scratches on the crystal or obvious wear to the PVD coating, suggesting it is a contemporary piece, likely assembled within the last 5 years. This item represents the popular 'modding' culture where Seiko components are combined with aftermarket parts to create bespoke timepieces inspired by luxury Swiss designs like the Rolex GMT-Master II.
