Davosa Argonautic Lumis BS Automatic
The DAVOSA Argonautic Lumis BS Automatic is a 30 ATM dive watch built around sustained low-light legibility. Borosilicate tubes filled with a gaseous tritium mixture sit on the hands and hour markers, providing continuous illumination without needing to be charged by an outside light source.
The tubes are held in custom index mounts and embedded in shockproof gel. A BGW09 Super-LumiNova dot marks the seconds hand, and another luminous dot sits in the ceramic bezel’s top triangle. A marked helium valve appears at 10 o’clock.
Inside, the Swiss 26-jewel DAV3021 automatic movement runs at 4 Hz. A screw-down crown, screw-in back, unidirectional bezel, sapphire crystal, and stainless steel bracelet complete the dive-watch structure.
