DAVOSA Argonautic Lumis BS Automatic – Tritium-Illuminated Diver (43 mm, 300 m)

A purpose-built dive watch engineered for low-light clarity, the Argonautic Lumis BS uses self-powered tritium gas tubes on the hands and hour markers for constant glow—no charging needed. A guilloché wave-pattern inner dial, conical ceramic bezel with luminous pip, and a helium valve at 10 o’clock round out a rugged 316L steel build with domed, anti-reflective sapphire.

Key Features:

Constant Glow Tritium — Borosilicate gas-tube markers on hands and indices deliver steady luminosity in total darkness; custom mounts sit in shock-absorbing gel.
Dive-Ready Construction — 30 ATM (300 m) water resistance, screw-down crown, and screw-in back for real-world reliability.
High-Tech Bezel — Unidirectional ceramic insert rises conically; luminous pip in the top triangle for orientation.
Sapphire Clarity — Domed, scratch-resistant sapphire crystal with anti-reflective treatment.
Legible Details — Guilloché wave inner dial; BGW9 Super-LumiNova dot on the seconds hand; subtle date aperture.
Stainless Bracelet — Solid 316L bracelet for secure, everyday wear.
