About this entry
89% of key specs known. Missing: hardening, bracelet links.
Islander's first "traveler" (flyer) GMT: the Port Jefferson skin diver case with a Miyota 9075, whose local hour hand jumps in one-hour steps (forwards or backwards, date following) while the 24-hour hand keeps home time; colour-matched date at 6. Bidirectional bezel with a 24-hour aluminium insert for a third time zone; 120 clicks per aBlogtoWatch (not stated by the brand). Lume: C3 Super-LumiNova on the indices and hands, BGW9 on the bezel insert (aBlogtoWatch adds BGW9 on the GMT hand tip). "13.2mm thick to the apex of the crystal" and 47.8mm lug to lug per the brand; Primer Peak measured 13.8mm and 47.9mm. Single-domed sapphire with AR on the underside, screw-down crown, embossed solid screw-down caseback, 150m. Case "Stainless Steel" (Primer Peak says 316L; not stated by the brand). Weight: the brand gives 170g "with bracelet"; the 82g head weight is from aBlogtoWatch. Bracelet: beads of rice with articulating negative end links, solid links and end links, sized with screws, 20mm tapering to 18mm, signed clasp with a double push-button release and spring-bar micro-adjust holes (no fold-over safety, per Primer Peak). Micro-adjust count conflict: the brand's copy says "3 positions", while aBlogtoWatch counted four holes and Primer Peak four positions, so positions are left out. Launched at $579 in 2024 (aBlogtoWatch, Primer Peak); $595 was the last listed price. All five references are tagged "Discontinued" and were sold out on 2026-10-21.
