The Mühle-Glashütte Teutonia IV Moonphase on a stainless steel bracelet is the most complete expression of this watch. The moonphase complication — where a crater-detailed disc rotates beneath a specially shaped window at 6 o'clock, displaying the 29.5-day lunar cycle — is inherently romantic. But on a steel bracelet with butterfly clasp, it gains a permanence and presence that positions it as a daily-wear business watch rather than a dressy special-occasion piece. This is the configuration for someone who wants the poetry of a moonphase on their wrist every day, not just on the days that call for leather.
The blue PVD lance-shaped hands are what tie the dial together. The blue matches the deep night-sky background of the moonphase disc, carrying that colour across the white grained dial surface and creating a visual thread between the complication and the time display. Applied steel indices sit cleanly against the textured dial, and the minute scale on the rehaut keeps the main face uncluttered. The bevelled roof bezel creates an angular transition from case to crystal, giving the 41mm case a modern, architectural quality, while the signature volute-shaped horns with hand-applied vertical cuts connect it unmistakably to the Teutonia family.
Inside, the SW 280-1 in the Mühle version — a calibre designed specifically for moonphase complications — features the brand's patented woodpecker neck regulation, Mühle rotor, blued screws, and Glashütte solarisation finishing. The exhibition caseback puts all of this on display. The stainless steel bracelet adds visual weight and a polished presence that makes the moonphase feel less like a delicate complication and more like a tool for reading the natural world — exactly the kind of functional precision that has defined Mühle-Glashütte since 1869.

Key Features
- Moonphase display — An approximately 10mm moon disc rotates once every 59 days beneath a specially shaped window at 6 o'clock. The moon appears twice on the disc, covering two full 29.5-day lunar cycles. The moon surface is rendered with realistic crater texture against a deep blue background
- Blue PVD lance-shaped hands — The distinctive lance-shaped profile and blue PVD coating are unique to the Teutonia IV. The blue matches the moonphase disc, creating a deliberate colour dialogue between the hands and the complication
- SW 280-1, Mühle Version — A Sellita calibre purpose-built for moonphase complications, refined in Glashütte with the patented woodpecker neck regulation, Mühle rotor, blued screws, Glashütte solarisation, and perlage finishing
- Patented woodpecker neck regulation — Developed in 2003, the spring's distinctive shape locks the regulator arm both sideways and downward onto the balance cock, delivering superior shock resistance compared to a traditional swan neck regulator
- Stainless steel bracelet with butterfly clasp — 20mm bracelet with a secure folding deployment clasp. The steel complements the blue hands and white dial, adding presence and versatility for daily wear across business and casual contexts
- Bevelled roof bezel and volute-shaped horns — The Teutonia IV's roof bezel creates an angular, modern transition from case to crystal, while the hand-finished volute-shaped horns with vertical cuts and polished tops anchor it to the Teutonia family

The Glashütte Difference
- Glashütte, Saxony — Germany's most storied watchmaking town, home to A. Lange & Söhne, Glashütte Original, NOMOS, and Mühle-Glashütte. Every Mühle watch is assembled, regulated, and tested here
- Six generations, one family — Founded by Robert Mühle in 1869 as a maker of precision measuring instruments for Glashütte's watchmakers. The company survived two World Wars, Soviet-era expropriation, and reunification. Now led by Thilo Mühle, with the sixth generation already on board
- Teutonia II to Teutonia IV — The Teutonia IV represents Mühle's modern evolution of their flagship collection. Where the Teutonia II uses guilloché dials, ray-cut finishing, and stepped or D-bezels, the Teutonia IV strips back to grained dials, bevelled roof bezels, and straighter lines — a more contemporary interpretation of the same Glashütte values
- Patented innovation — The woodpecker neck regulation (2003), Mühle three-quarter plate (2008), and proprietary in-house calibres (MU 9408, MU 9411) demonstrate that this is a manufacturer, not merely an assembler

Frequently Asked Questions
What's the difference between this (M1-44-05-MB) and the leather version (M1-44-05-LB)?
Identical watch — same white grained dial, same moonphase complication, same SW 280-1 movement, same case, same exhibition caseback. The only difference is the strap. The LB comes on a black crocodile leather strap with butterfly clasp — the more formal, dressy configuration for suits and evening wear. The MB (this model) comes on a stainless steel bracelet with butterfly clasp — more versatile, more substantial on the wrist, suited to daily business wear and smart casual contexts alike. The bracelet makes the moonphase feel like a daily-wear complication rather than a special-occasion one.
How does the moonphase work?
A disc approximately 10mm in diameter sits beneath a specially shaped window at 6 o'clock. The moon appears twice on the disc — once on each half. The disc completes one full rotation every 59 days, which means each moon passes through the window every 29.5 days, matching the real lunar cycle. As the disc rotates, the window gradually reveals and then conceals the moon, displaying new moon, waxing crescent, first quarter, full moon, waning crescent, and last quarter in realistic one-day increments.
How accurate is the moonphase?
The moonphase mechanism uses a 59-day gear, which divides the lunar month into 29.5-day cycles. The actual lunar cycle is 29.53059 days, so over time the display will drift slightly — approximately one day every 2.7 years. This can be corrected quickly via the crown.
How does this compare to the other Teutonia models City Chain carries?
City Chain carries four Teutonia families. The Teutonia II Small Second (M1-33-42-MB) is classical — midnight blue ray-cut dial with off-centre seconds. The Teutonia II Day/Date (M1-33-65-MB) is the most practical — silver guilloché dial with day and date. The Teutonia II Chronometer (M1-30-45-LB) is the most precise — observatory-certified accuracy. The Teutonia IV Moonphase (this model) is the most romantic and modern — moonphase complication with blue lance-shaped hands on a clean, contemporary white dial. Choose by what you value most: classical tradition, daily information, certified precision, or poetic complication with modern design.
What is the woodpecker neck regulation?
Developed and patented by Mühle-Glashütte in 2003, the woodpecker neck regulation is a further evolution of the traditional Glashütte swan neck fine adjustment. Its specially shaped spring locks the regulator arm both sideways against the fine adjustment screw and downward onto the balance cock. This dual-axis pressure prevents the arm from jumping out of position during shocks. Originally developed for the S.A.R. Rescue-Timer used in German maritime rescue, it is now fitted to every Mühle movement.
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, Glashütte solarisation, perlage finishing, and blued screws are all applied in-house. The case, dial assembly, moonphase module installation, and final quality control 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 — simply wear it or give the crown a few manual winds to restart. The moonphase display will also need to be re-set to the current lunar phase if the watch stops.
Is this a good gift?
One of the most meaningful gifts in the Mühle-Glashütte collection. A moonphase connects the wearer to the natural world in a way that hours and minutes alone cannot — and on a steel bracelet, it's a gift they'll wear every day rather than save for occasions. The blue lance-shaped hands, the crater-detailed moon disc, the exhibition caseback, and the story of a six-generation German watchmaking family give this watch an emotional depth that goes well beyond its material value. An exceptional choice for weddings, anniversaries, milestone birthdays, and Father's Day.
