The Mühle-Glashütte S.A.R. Rescue-Timer Nautical Blue on blue rubber is the purest maritime expression of the Rescue-Timer. Blue dial, blue rubber bezel, blue rubber strap — every external surface references the sea this watch was built for. It is monochromatic in a way the metal bracelet variant cannot be, and operationally ready in a way the bracelet doesn't need to be. The rubber strap resists saltwater, UV, and chemicals without question. The rubber bezel absorbs impacts and eliminates injury-causing edges. And the 100 bar water resistance means the entire watch can go wherever the ocean demands.
The nautical blue dial with bright white Super-LumiNova markers delivers the same high-contrast readability as the standard black S.A.R. — but with more character. The white triangular indices and bold hour markers pop against the deep blue background with exceptional clarity, and the generous Super-LumiNova coverage ensures the dial remains fully legible in total darkness. The 4mm anti-reflective sapphire crystal — three times the standard thickness, with the date magnifier cut into the underside — protects everything behind it.
Inside, the SW 200-1 in the Mühle version features the patented woodpecker neck regulation — the shock-resistant system originally developed for this watch. The rubber-on-rubber configuration (blue strap, blue bezel) makes this the lightest Nautical Blue variant and the most comfortable for extended wear during active use. It's the S.A.R. dressed for the water, by a manufacturer that knows water better than almost any other watchmaker in Germany.

Why You'll Love It
- Full nautical blue — dial, bezel, and strap in one unified maritime colour. The most visually cohesive S.A.R. Rescue-Timer in the collection
- 100 bar water resistance — the full Rescue-Timer specification, pressure-tested to 1,000 metres equivalent. Ten times the 29er and Teutonia rating
- Blue rubber strap with folding clasp — saltwater-proof, UV-resistant, lightweight, and operationally ready. The lightest Nautical Blue configuration
- 4mm sapphire crystal with integrated date magnifier — three times the standard thickness, with the lens cut into the underside so it cannot be knocked off
- White Super-LumiNova on deep blue — bold high-contrast markers that are immediately legible in all conditions, from bright sun to total darkness
- The watch the woodpecker neck regulation was invented for — the patented shock-resistant system originated here before being adopted across every Mühle collection
Perfect For
Key Features
- 100 bar (1,000m) water resistance — Pressure-tested for saltwater, sudden temperature changes, and high-pressure hose-downs. Screw-down crown. The rubber strap and rubber bezel are inherently water-proof — no concerns about saltwater degradation that metal can face over time without rinsing
- Nautical blue dial with white Super-LumiNova — Deep blue background with bold white triangular indices and hour markers. The white-on-blue contrast is exceptionally clean, and the generous Super-LumiNova ensures full legibility in darkness
- Blue rubber bezel — The same safety bezel from the standard S.A.R. — absorbs lateral impacts, eliminates sharp edges that could injure people during rescue — in matching nautical blue
- 4mm anti-reflective sapphire crystal — Three times the standard thickness. Date magnifier cut into the underside — nothing raised that can be knocked off
- SW 200-1, Mühle Version with patented woodpecker neck regulation — Originally developed for this watch. The spring locks the regulator arm in two axes simultaneously, preventing displacement during impacts
- Blue rubber strap with folding clasp — 20mm strap resistant to saltwater, UV, and chemicals. The folding clasp provides secure closure. Lighter on the wrist than the metal bracelet variant, making it the preferred configuration for extended active wear

Frequently Asked Questions
What's the difference between this (rubber) and the bracelet version (M1-41-02-MB-II)?
Identical watch — same nautical blue dial, same blue rubber bezel, same 100 bar water resistance, same 4mm sapphire crystal, same movement. The only difference is the strap. The KB-II (this model) comes on a blue rubber strap with folding clasp — lighter, fully waterproof, and the most operationally native configuration. The MB-II comes on a stainless steel bracelet with butterfly clasp — heavier, more polished, and versatile enough for business and evening contexts. Choose rubber for water sports and active wear. Choose bracelet for daily versatility and wrist presence.
How does the Nautical Blue compare to the standard black S.A.R.?
Identical specifications: 42mm case, 100 bar water resistance, 4mm sapphire crystal, rubber safety bezel, SW 200-1 with woodpecker neck regulation. The difference is colour. The standard (M1-41-03) has a black dial and black bezel — operationally invisible. The Nautical Blue (M1-41-02) has a deep blue dial and blue bezel — the maritime personality that the standard deliberately avoids. Same rescue-grade performance, different character.
How does this compare to the S.A.R. Lumen?
The Lumen (M1-41-08) coats the entire dial in Super-LumiNova — a cream dial that glows blue-green in darkness with skeletonized hands. Maximum night readability. The Nautical Blue (M1-41-02) uses a conventional blue dial with Super-LumiNova on the hands and indices — excellent readability, but without the full-lume light-source effect. Choose the Lumen for extreme darkness performance. Choose the Nautical Blue for the most maritime-looking S.A.R. in the collection.
Why is the sapphire crystal 4mm thick?
Three times the standard thickness, providing dramatically greater impact resistance for environments where collisions with deck equipment and rescue hardware are routine. The date magnifier is cut into the underside — nothing raised that can be knocked off.
What is the woodpecker neck regulation?
Developed and patented by Mühle-Glashütte in 2003 specifically for the S.A.R. Rescue-Timer, the woodpecker neck regulation locks the regulator arm both sideways and downward, preventing it from jumping out of position during shocks. Adopted across every Mühle movement since.
Is this watch made in Germany?
Yes. While the base calibre is Swiss-made (Sellita), it is refined, regulated, and finished in Mühle-Glashütte's own manufactory in Glashütte, Saxony. The woodpecker neck regulation, Mühle rotor, and all finishing are applied in-house. The case, dial assembly, and final quality control — including 100 bar pressure testing — are performed in Glashütte.
How long does the power reserve last?
Up to 41 hours when fully wound. The automatic movement is self-winding through wrist motion. If left unworn for roughly two days, the watch will stop and need to be set again.
Is this a good gift?
Excellent for anyone who loves the water. The all-blue configuration — dial, bezel, strap — is immediately striking, the 100 bar rating means they'll never worry about damaging it in the ocean, and the DGzRS rescue heritage gives the gift a story with genuine depth. The rubber strap means they can wear it into the pool on the day they unwrap it. An outstanding choice for divers, sailors, water sports enthusiasts, and anyone who'd rather be near the sea than away from it.
