Miyota 9039 (true no-date) Brookville Hi-Beat; the Miyota 9015 versions are separate files, as is the later Calligraphy Edition (which also uses the 9039 on ISL-320/321/339). 38 x 11mm, 44.5mm lug to lug, 20mm lugs, screw-down crown, 100m, screw-in exhibition caseback showing a custom blue Islander rotor. Polished sides, fine-brushed top, smooth bezel. Applied hour markers (white-outlined on ISL-239, gunmetal on ISL-199) and hands filled with Super-LumiNova (grade not stated). Flat anti-reflective sapphire (side not stated). Weight 125g from the spec table (not stated what was weighed). Bracelet: solid links and solid female end links sized with screws, 20mm tapering to 16mm, push-button deployant clasp (micro-adjust not stated); 3-link style in the photos. ISL-239 has an abalone dial (each one differs); ISL-199 a green sunburst dial with a darker bamboo pattern, with 10% of revenue donated to the World Wildlife Fund. Both are tagged "Discontinued" in the store's product data and were sold out on 2026-10-21.
