About this entry

79% of key specs known. Missing: weight, hardening, end links, clasp micro-adjust.

38mm steel tritium diver, six "Pre-Order Sea Sentinel Tritium" listings at USD 699 ("Ships in November 2026"; the "save $200 automatically" pre-order offer is not recorded). The listings were created in March 2025 under the name "Sea Dragon" (still in the handles and photo file names). Brand specs: 316L steel, brushed with polished edges, 38mm x 12.8mm, 46mm lug to lug, 20mm lugs, screw-down crown, sapphire with blue AR coating on the underside, sapphire display caseback, 120-click unidirectional bezel with a polished ceramic insert lumed with Swiss Super-LumiNova C3 ("GLC3 Grade A"), Swiss MB Microtec T-100 tritium, 300m, bracelet tapering 20 to 16mm with screwed links and a proprietary clasp with 6 micro-adjust positions (type not stated), black rubber strap. The full spec table is only on the DLC listing; the others give the same figures in their text. Movement: Miyota 9015, "precisely regulated by Aquatico for an accuracy of +/- 8 seconds per day". The DLC Black variant has a black DLC-coated case and bracelet (the listing doesn't say whether the coating is for hardness). The photos show three links across. No weight is given. Each listing says "Limited Edition 100 pieces worldwide", recorded per dial. All six were available to order on 2026-10-25.
