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

The Mühle-Glashütte S.A.R. Rescue-Timer Lumen on a metal/rubber strap is the most versatile configuration of the full-lume Rescue-Timer. It pairs the watch that turns night into day — the entire cream dial coated in Super-LumiNova, glowing vivid blue-green in darkness — with a strap that bridges the gap between the pure rubber variants and the full metal bracelet. Stainless steel links provide the visual weight and polished presence of metal, while rubber inserts add flex, comfort, and resistance to saltwater, chemicals, and UV exposure.

The Lumen concept inverts how a watch works in the dark. Instead of luminous hands and indices against a black dial, the entire dial surface is Super-LumiNova. The hands are skeletonized and painted black, becoming dark silhouettes against a glowing field. In daylight: warm cream dial, black hands, sharp contrast. In total darkness: the dial ignites, and the hands cut dark shapes through the light. 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 safety bezel, and the SW 200-1 in the Mühle version with the patented woodpecker neck regulation — the shock-resistant system originally developed for this watch. The metal/rubber strap adds a level of finish that makes the Lumen equally at home on a dive boat and at a weekend dinner.

Key Features

• Full Super-LumiNova dial — The entire cream dial is coated with Super-LumiNova. In daylight: warm cream. In darkness: vivid blue-green glow across the full face. The dial becomes a light source — dramatically more readable in total darkness than conventional luminous markers
• Skeletonized black hands — Cut open and painted black, readable in daylight as sharp outlines on cream, and in darkness as dark silhouettes against the glowing dial. Two mechanisms, one design
• Metal/rubber combination strap with folding clasp — 20mm strap combining stainless steel links and rubber inserts. The metal provides structure, weight, and visual polish. The rubber provides flex, comfort, and total resistance to saltwater, UV, and chemicals. Secured with a folding clasp
• 100 bar (1,000m) water resistance — Pressure-tested for saltwater, sudden temperature changes, and high-pressure hose-downs. Screw-down crown. Ten times the rating of the 29er and Teutonia collections
• 4mm anti-reflective sapphire crystal — Three times the standard thickness. Date magnifier cut into the underside — nothing raised that can be knocked off
• Rubber bezel — Absorbs lateral impacts and eliminates sharp edges that could injure people during rescue. Safety-first design from the DGzRS coxswains
