About this entry

53% of key specs known. Missing: lug-to-lug, lug width, weight, hardening, AR coating, crown, end links, link attachment, clasp micro-adjust.

Seestern's "Series: S477", sold on Sugess's store as six listings: E blue, G green and P purple textured dials (colours from the SKU names), each with a lumed black ceramic bezel insert (EC, GC, PC) or a steel bezel insert (ES, GS, PS), all at the same price. The dial is printed "Seestern Season" and "Limited Edition"; the store gives no edition size, so status is limited without a number. Brand specs: 316L case, 39.5mm, 10mm thick or 12mm with the crystal, sapphire crystal, "Lumed Ceramic Bezel Insert" or "Steel Bezel Insert", 316L steel bracelet with a "Folding Quick Mirco Adjust Buckle" (a photo shows a sliding extension in the clasp; how it is operated is not stated), Seagull ST2130 (25 jewels, 4Hz, 40h), 100m. The store's tags say "NH35", but the spec table names the ST2130 and its 4Hz rate rules out an NH35 (3Hz), so the ST2130 is recorded. The 60-minute bezel scale, five-link jubilee-style bracelet, lumed hands and indices and display caseback are from the product photos. Dial material, lug-to-lug, lug width, crown type, bezel action, AR coating, lume type and weight are not stated, and no review with measurements was found. The store's "compare at" prices are not recorded.
