About this entry
73% of key specs known. Missing: lug-to-lug, lug width, weight, hardening.
The titanium Aquadeep dive case with a Time Module (Seiko) NH36 day-date automatic, sold as the Aquadeep Submerge (listed 2024-01-25). The other titanium Aquadeep builds (NH35, NH37, NH34 GMT) are separate models. Spec table: "Japanese NH36 Automatic Winding Mechanism", "Titanium case with DLC black color with ceramic bezel, screw crown", "Sapphire glass with AR coating" (side not stated), 43mm, 16.5mm (the table does not say whether the crystal is included; the NH35 Aquadeep listings give 16.5mm including it), 50 ATM / 500m. The description adds a helium escape valve, a "thick sapphire crystal", a "jet-black sandblasted finish", a textured black dial and "applied Swiss Super-LumiNova indexes", and the day-date window shows at 3 o'clock in the photos. The caseback photo shows a solid back engraved with a submarine. No lug-to-lug, lug width, weight or bezel action is published. The listing was sold out on 2026-10-30, and the 2026 Submerge Carbon listings say the first Submerge "quickly sold out"; Undone does not say whether it will return, so the status is left unknown. Editions. Submerge (AQD-DEP-SMG, USD 395): black DLC titanium case, black ceramic bezel insert, textured black "abyss" dial with orange "AQUADEEP" print, orange rubber strap.
