About this entry

79% of key specs known. Missing: weight, hardening, bracelet links, end links.

Fixed-bezel Seaforth IV (40mm); the rotating-bezel version is 41mm and is a separate file. Current batch is titanium only, no-date, with the Sellita SW200-2 (brand: 65h power reserve); earlier batches used the SW200-1, and earlier Seaforth IV runs were also made in steel. Titanium grade not stated. Dial colours: Sunburst Blue, Sunburst Plum, Sunburst Grey, Pastel Blue, Bahama Yellow and O.W.W.W. Pink, all at the same price. Every configuration includes a rubber strap; the bracelet option adds a titanium bracelet with a stainless steel clasp. Sold in batches by pre-order: on 2026-10-20 the Dec 2026 / Jan 2027 batch was closed and all variants showed "sold out"; prices are the store's regular listed prices. Clasp: the brand gives no details; Dialicious describes "a clasp allowing fast tool-free micro-adjustment" and Two Broke Watch Snobs calls it a tool-free adjustment system for "dialing in fit on the fly", which is the basis for on-the-fly (positions, range, clasp type not confirmed). Bracelet style, end links, taper and quick-release not stated. "Anti-reflective coating" side not stated. Weight not published.
