About this entry

93% of key specs known. Missing: hardening.

Grade 5 titanium diver platform (case, caseback and bezel), launched as the SEALAB in December 2025 and followed by the yellow-dial Poseidon in 2026, which the brand describes as the same platform and movement; each is limited to 500 pieces. Brand specs: 41mm, 11.9mm thick, 45mm lug to lug, 20mm lugs, about 50g (head only per the full spec list), 300m, flat sapphire with triple AR coating, unidirectional 120-click bezel with a US Navy no-decompression table, screw-down crown, screw-down engraved caseback, applied markers with X1 Super-LumiNova, La Joux-Perret G100 in Soigné grade adjusted in 4 positions (60-hour power reserve quoted), Tropic rubber strap. The spec lists give the functions as hours, minutes and seconds, but the dials show a date at 3. Two Broke Watch Snobs gave the SEALAB's launch pricing as USD 990 pre-order, then USD 1,390 MSRP; on 2026-10-30 both versions were in stock at USD 1,390 against a regular USD 1,490. The Ti300M Poseidon Deep Black uses a Sellita SW200-1 and is a separate model.
