Mühle-Glashütte Seebataillon GMT M1-28-62-KB

The Mühle-Glashütte Seebataillon GMT is the only watch in the Mühle collection developed for military operations. It was created in direct consultation with the command staff of the German Navy's Seebataillon (Sea Battalion) — a specialised unit responsible for protecting naval vessels, personnel, and assets in foreign ports and on the high seas, including anti-piracy missions, embargo checks, and maritime security deployments from the coast of Africa to the Middle East. The soldiers needed a watch that could survive any theatre of operation, track a second time zone for overseas deployment, and be read instantly in any conditions. Mühle built exactly that.

The titanium case is the first thing you feel — or rather, don't feel. At 45mm in diameter but constructed entirely from titanium, the Seebataillon GMT wears significantly lighter than its size suggests. Titanium is approximately 45% lighter than stainless steel, naturally corrosion-resistant against saltwater, and hypoallergenic. The crown at 4 o'clock — not the standard 3 — is a deliberate tactical choice: it prevents the crown from digging into the back of the hand or snagging on equipment during physical operations. The bidirectional rotating bezel with aluminium 24-hour insert assists with time tracking, while double indices at 3, 6, and 9 o'clock and a split triangular marker at 12 o'clock ensure instant readability.

The SW 330-2 in the Mühle version powers the GMT complication — a dedicated fourth hand that tracks a second time zone on a 24-hour scale, essential for a unit that deploys globally and needs to reference home time at a glance. The patented woodpecker neck regulation, Mühle rotor, and Glashütte finishing are all present. The exhibition caseback is engraved with the coordinates of the Seebataillon headquarters, and the automatic rotor carries the Seebataillon coat of arms. For soldiers of the unit, their watches are further personalised with their individual personnel number. It is, quite literally, a military-issue timepiece available to the public.

Key Features

• GMT / second time zone — A dedicated fourth hand (the GMT hand) completes one rotation every 24 hours, indicating a second time zone on the bezel's 24-hour scale. Essential for soldiers deployed overseas, equally useful for business travellers and anyone with international connections. The local time is set via the standard hour hand, which can be adjusted independently in one-hour increments without stopping the movement
• Titanium case with crown at 4 o'clock — Titanium is approximately 45% lighter than stainless steel, naturally resistant to saltwater corrosion, and hypoallergenic. The crown at 4 o'clock is a military-derived specification that prevents the crown from pressing into the back of the hand during grip-intensive tasks — a genuine ergonomic advantage for active wear
• SW 330-2, Mühle Version — A Sellita calibre with GMT module, refined in Glashütte with the patented woodpecker neck regulation, Mühle rotor, blued screws, Glashütte solarisation, and perlage finishing. 56-hour power reserve — the longest in the Mühle catalogue
• Double indices and split triangle marker — The dial features double indices at 3, 6, and 9 o'clock and a split triangular marker at 12 o'clock. This layout was specified by the Seebataillon for instant directional readability — you can orient the dial at a glance without reading numbers. Super-LumiNova coating ensures full legibility in darkness
• Bidirectional rotating bezel — Aluminium 24-hour insert for GMT time tracking. The bidirectional rotation allows the bezel to be set in either direction for quick reference
• Seebataillon engravings — The automatic rotor carries the Seebataillon coat of arms, and the exhibition caseback is engraved with the coordinates of the unit's headquarters — a direct lineage to the military origin of this watch

Technical Specifications

Built for the German Navy, Made in Glashütte

• The Seebataillon — The Sea Battalion of the German Navy protects naval vessels, personnel, and assets in foreign ports and on the high seas. Their operational remit includes anti-piracy missions, embargo checks, boarding operations, and maritime security across theatres from the coast of Africa to the Middle East. They need a watch that works in every one of those environments
• From S.A.R. to Seebataillon — The soldiers first encountered Mühle-Glashütte through the S.A.R. Flieger-Chronograph on board naval rescue aircraft. In 2012 they approached Mühle directly to develop a dedicated unit watch. The result — launched in 2013 — combines the S.A.R.'s tool-watch DNA with a GMT complication, titanium construction, and military-specific ergonomics
• Where the woodpecker neck regulation was born — Developed for the S.A.R. Rescue-Timer and now standard across every Mühle movement, the patented shock-resistant regulation ensures the Seebataillon GMT maintains accuracy under the same physical demands that inspired its creation
• 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
