About this entry

74% of key specs known. Missing: lug width, weight, hardening, end links, link attachment.

Brand specs: Seagull ST2130 automatic, 316L, 40mm, 48mm lug-to-lug, 13.2mm including crystal, sapphire with AR coating (side not stated), ceramic bezel with lume, gradient black, blue or green dial with applied indices and hexagon logo, lumed sword hands, BGW-X1 blue lume on hands and markers, screw-down crown with hexagon logo, screw-down caseback with San Martin logo, 316L solid bracelet with the "New Fly Adjustable Clasp" (on-the-fly; positions and range not stated), 300m. Lug width, weight and bezel rotation are not stated; the 60-minute scale, the textured dial and the 3-link oyster-style bracelet are from photos. The ST2130 is a date caliber, but no SN0154 dial in the photos shows a date window, so complications are time only. The store spells the colour options "Gradiend". $388 for any colour; all three in stock on 2026-10-25. The listing is filed under the store's "Pre-Order Model" category.
