The S.A.R. Rescue-Timer (ref. M1-41-03-KB) is Mühle-Glashütte's tool-diver — 42mm steel, 1,000m water resistance, the patented Mühle woodpecker-neck regulator on a Sellita SW 200-1 base, orange minute hand, and a ratcheting unidirectional bezel calibrated for elapsed-dive timing. It was developed in cooperation with the DGzRS (the German Maritime Search and Rescue Service) and is the issue watch for the orange-and-white boats that patrol the North Sea and Baltic.

What it is

Mühle-Glashütte and the DGzRS began collaboration in 2002 on a dive watch specified for sea-rescue use — the brief asked for legibility under sea-spray, a one-handed bezel-grip, and water-resistance well beyond civilian-dive depths. The S.A.R. Rescue-Timer launched that year and has been continuously produced since, with updated movement and bezel-grip iterations every five-to-seven years.

The current generation carries the brand's woodpecker-neck regulator on a Sellita SW 200-1 base and the rubber-grip bezel introduced in 2019. The watch is licensed by the DGzRS — a portion of each sale supports the German sea-rescue service.

Buying notes

Common things to check: bezel grip (the rubber bezel grip is consumable — the current generation uses a replaceable insert, but earlier generations had it bonded; verify generation against year of production); helium-escape valve (the S.A.R. Rescue-Timer does not include one and is not saturation-rated despite the 1,000m figure — divers should not confuse it with a Sea-Dweller / Deep Sea Special); papers and the DGzRS license card (the watch ships with a DGzRS certificate — verify it is present); caliber verification (the cal. MU 9415 is a Sellita SW 200-1 base with the woodpecker-neck regulator — verify the patent-marked balance bridge through the case-back); strap (the watch ships on either rubber or fabric — confirm which is included).

Market read

S.A.R. Rescue-Timer examples trade in the $2,200-$2,700 range through 2025-2026, against a current retail of approximately $3,000. The reference has the strongest in-the-trade reputation of any Mühle product — issued-watch credibility (the DGzRS connection is real, not marketing) drives a small but durable collector audience.

Pricing has been stable for years. Cross-shopped against the Sinn U1 or the Damasko DSub1, the S.A.R. carries the haute-Glashütte address and the woodpecker-neck regulator at a comparable price.

Service expectations

Service is performed by Mühle-Glashütte's German service center or through the brand's authorized US service partner. Expect 4-6 month turnaround and a low-four-figure service bill. The Sellita SW 200-1 base is the most-serviced ETA-compatible movement in the modern catalog; parts availability is excellent.

Water-resistance testing is part of every factory service. Service intervals of 5-7 years are typical for non-dive use; an example used for actual diving should be pressure-tested annually.
