Mühle-Glashütte S.A.R. Rescue-Timer Lumen M1-41-08-KB

The Mühle-Glashütte S.A.R. Rescue-Timer Lumen takes the toughest watch in the Mühle collection and turns night into day. The concept is an inversion: instead of applying Super-LumiNova to the hands and indices only, the entire dial surface is coated in Super-LumiNova. The hands are skeletonized — cut open and painted black — so they appear as dark silhouettes against a glowing blue-green field. In daylight, the cream-coloured dial is warm and readable with black hands. In darkness, the entire face ignites — the most luminous dial Mühle has ever produced.

This is not a design gimmick. Maritime rescue happens overwhelmingly at night. The DGzRS coxswains operate in conditions where ambient light is zero — no streetlights, no moon, just sea and sky. The standard S.A.R. Rescue-Timer uses luminous hands and indices against a black dial — bright marks in a dark field. The Lumen reverses the principle — a bright field with dark marks — and the result is dramatically more readable in pitch darkness because the entire dial becomes a light source. You don't find the hands against the dark. The hands find you against the light.

Everything else is pure Rescue-Timer. 100 bar water resistance. 4mm anti-reflective sapphire crystal with the date magnifier cut into the underside. Rubber bezel for impact and personnel safety. The SW 200-1 in the Mühle version with the patented woodpecker neck regulation — the shock-resistant system originally developed for this watch. And the red rubber strap that has become the visual signature of the S.A.R. collection — DGzRS rescue red, visible even in heavy seas.

Key Features

• Full Super-LumiNova dial — The entire cream dial surface is coated with Super-LumiNova. In daylight, it reads as warm cream. In darkness, it ignites into a vivid blue-green field. This is not accent lume — the entire face becomes a light source, providing dramatically more readable information in total darkness than conventional luminous markers alone
• Skeletonized black hands — The hour and minute hands are painted black and cut open (skeletonized), creating dark silhouettes against the glowing dial. In daylight: black on cream for clear contrast. In darkness: dark outlines against blue-green lume. The readability logic is inverted from the standard S.A.R. — and more effective in the pitch-dark conditions of maritime rescue
• 100 bar (1,000m) water resistance — Identical to the standard S.A.R. Rescue-Timer. The case is pressure-tested for saltwater, sudden temperature changes, and high-pressure hose-downs. Screw-down crown seals the case completely
• 4mm anti-reflective sapphire crystal — Three times the thickness of a standard sapphire. The date magnifying lens is cut into the underside — nothing raised that can be knocked off
• Rubber bezel — Absorbs impact, protects the crystal and case, and eliminates sharp edges that could injure people during rescue operations
• Red rubber strap with folding clasp — 20mm strap resistant to saltwater, UV, and chemicals. The DGzRS rescue red is a deliberate visibility choice

Technical Specifications

Built for Rescue, Made in Glashütte

• Why full lume? — Maritime rescue happens overwhelmingly at night. The standard S.A.R. uses luminous markers against a dark dial — bright points in a dark field. The Lumen inverts this: a fully luminous dial with dark hands. The result is a light source, not a collection of light points — dramatically more readable when ambient light is zero
• Developed with the DGzRS — The German Maritime Search and Rescue Service operates over 60 rescue vessels across the North Sea and Baltic Sea. Their coxswains co-designed the S.A.R. Rescue-Timer for the specific demands of open-ocean rescue — and the Lumen variant pushes its night-readability to the absolute limit
• Where the woodpecker neck regulation was born — The patented shock-resistant regulation was engineered specifically for the S.A.R. Rescue-Timer before being adopted across every Mühle movement in every collection
• Glashütte, Saxony — Every Mühle watch is assembled, regulated, and tested in Germany's most storied watchmaking town — the same town where A. Lange & Söhne and Glashütte Original are made
