Miyota 90S5 version of the Brookville Calligraphy Edition (ISL-367 and ISL-368 were listed as new arrivals on 2026-09-29; ISL-319 is also described and spec'd with the 90S5 now). The earlier ISL-320/321/339 use the Miyota 9039 and cost $399 (separate file). Miyota sells the 90S5 as an open-heart caliber, but the brand calls it "a true no-date movement" and the product photos show a closed dial, so complications is empty. Same case and bracelet as the 9039 version: 38 x 11mm, 44.5mm lug to lug, 20mm lugs, diamond-style screw-down crown with cabochon, 100m, screw-down exhibition caseback with the blue Islander rotor, flat sapphire with inner AR. The brand only says the numerals and markers are "generously filled with lume" (no compound named). Case grade 316L is from the caseback engraving ("MATL: 316L SS") in the product photos (the pictured caseback is marked ISL-320). Weight 134g "on bracelet" from the spec table. Bracelet: 20mm with quick-release pins, female end links, brushed middle and outer links (3 per row, rounded, from photos), screws, tool-less micro-adjust clasp, tapering to 16mm; bonus FKM rubber strap with quick-release spring bars. All three were in stock on 2026-10-21.
