About this entry
89% of key specs known. Missing: hardening, bracelet links.
The smaller Northport, answering requests for a version of the 40.5mm original (first released in summer 2022, file northport): a different case and movement, so a separate model. 37mm, "an amazingly thin 11.7mm", 43.5mm lug to lug, 20mm lugs, female end links that articulate at the case, brushed top and sides including the signed screw-down crown, 200m, solid embossed screw-down caseback; stainless steel, grade not stated. Miyota 90S5 hi-beat (28,800 vph), "a true no-date movement" with no ghost crown position; hand-winds and hacks, about 40 hours per the brand. Miyota sells the 90S5 as an open-heart caliber, but the ripple dials are closed, so complications is empty. 120-click unidirectional coin-edge bezel with a sapphire insert (whether it is lumed is not stated). Flat sapphire with inner AR. Embossed ripple dials; lume on hands and indices is BGW9 on ISL-290 (gunmetal hands) and ISL-291 (silver hands), C3 on ISL-292 and ISL-293 (gunmetal hands). Weight 145g from the spec table (not stated what was weighed). Bracelet: fully brushed (tops and sides), solid links and solid end links sized with screws, 20mm tapering to 16mm, "fully milled 6 position ratcheting micro-adjust clasp" (spec table: "tool-less micro adjust deployant clasp"), recorded as toolless since on-the-wrist adjustment is not stated. The spec tables of all four call the bracelet "7-link", and ISL-290/291 are pictured on a 7-link beads-of-rice bracelet, but ISL-292/293 are pictured on a 3-link bracelet, so bracelet style is not recorded. All four are tagged "Discontinued" and were sold out on 2026-10-21; prices are the last listed ones; its product page still loads, so it keeps a store link. No independent review found.
