Prototype Core Divers with a solid 925 silver case, listed in December 2022 (three colours, $1699 each, plus a second, description-less listing of the black one a day earlier); no production run has been found in the store. Separated from the steel Core Diver (core-diver) because of the case material. Brand specs: "Solid 925 Silver case with brushed finishes and a stainless steel case back", 44mm without crown, 15.6mm thick (not stated whether with crystal; recorded as total), 50mm lug-to-lug, 22mm lugs, automatic helium escape valve at 9, 600m, all-sapphire unidirectional bezel with 120 clicks and Swiss C3 Super-LumiNova markers, 4.0mm sapphire crystal with an anti-reflective coating (side not stated), regulated Sellita SW200-1, 40-hour power reserve, "NEW Updated Shark Mesh Bracelet with Ratchet Extension Clasp" plus a rubber strap. The bracelet's material isn't stated. Dial colours other than the black (a tapisserie dial in the photo) aren't described.
