About this entry

93% of key specs known. Missing: hardening.

The Poseidon Deep Black shares the Ti300M's Grade 5 titanium case with the La Joux-Perret G100 versions (a separate model) but uses a Sellita SW200-1 adjusted in 4 positions (38-hour power reserve quoted), so it is recorded on its own. Brand specs: 41mm, 11.9mm thick, 45mm lug to lug, 20mm lugs, about 50g head only, 300m, flat sapphire with triple AR coating, unidirectional 120-click bezel with US Navy no-decompression table, screw-down crown and engraved caseback, matte black dial with "3D-BRYTE" indices (three-dimensional X1 Super-LumiNova pieces pinned to the dial), yellow and black rubber straps. The spec list gives the functions as hours, minutes and seconds, but the dial shows a date at 3. Limited to 300 pieces per year. Pre-order at USD 1,490 (regular USD 1,690, USD 500 deposit option); first batch shipping October 2026, second January 2027.
