The Mühle-Glashütte Teutonia IV Moonphase is the most romantic complication in the Mühle collection — and the most contemporary expression of the Teutonia design language. At 6 o'clock, a specially shaped window reveals a moon disc that rotates once every 59 days, displaying the approximately 29.5-day lunar cycle in realistic one-day increments. The moon itself is rendered with surface crater detail that imitates the real thing, set against a deep blue night-sky background. It's not an abstract symbol. It's a miniature portrait of the moon, turning slowly beneath the dial.
Everything about the dial is built around that moonphase window. The blue PVD lance-shaped hands — hour, minute, and seconds — pick up the blue of the moon disc and carry it across the white dial, creating a colour harmony that ties the entire face together. The finely grained dial surface provides a subtle texture that catches light without competing with the moonphase display. Applied indices sit cleanly and precisely, and the minute scale on the rehaut maintains the uncluttered philosophy that defines the Teutonia IV: reduced to the essentials, with every element earning its place.
The Teutonia IV represents Mühle's evolution of the Teutonia design. Where the Teutonia II uses guilloché dials, ray-cut finishing, and a stepped or D-bezel, the Teutonia IV strips back to a bevelled roof bezel, clean grained dial, and straighter lines — a more modern interpretation of the same Glashütte values. The volute-shaped horns with their hand-applied vertical cuts remain, connecting it unmistakably to the Teutonia family. Inside, the SW 280-1 in the Mühle version — a calibre designed for moonphase complications — features the patented woodpecker neck regulation, Mühle rotor, blued screws, and Glashütte solarisation finishing, all visible through the exhibition caseback.

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, so each rotation covers two full 29.5-day lunar cycles. The moon surface is rendered with realistic crater texture against a deep blue background — not an abstract crescent but a detailed miniature of the moon itself
- 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 — a design detail that unifies the dial
- 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
- Bevelled roof bezel and volute-shaped horns — The Teutonia IV's roof bezel creates a clean, angular transition from case to crystal, while the signature volute-shaped horns with hand-applied vertical cuts and finely polished tops connect it to the broader Teutonia family
- Crocodile leather strap with butterfly clasp — 20mm black crocodile leather with a secure folding deployment clasp. The formal strap matches the moonphase's dressy character

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. The signature volute-shaped horns with hand-applied vertical cuts remain, anchoring the IV to the family identity
- 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
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. The moon surface is detailed with crater texturing that imitates the real thing.
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. For practical purposes, it remains accurate enough that you can glance at the dial and know the current phase of the moon.
What's the difference between the Teutonia IV and the Teutonia II?
Both share the same Teutonia DNA — volute-shaped horns with hand-applied vertical cuts, exhibition casebacks, woodpecker neck regulation, and 10 bar water resistance. The difference is design philosophy. The Teutonia II uses guilloché or ray-cut dials, stepped B-bezels or D-bezels, and a more classical, layered aesthetic. The Teutonia IV strips back to grained dials, bevelled roof bezels, and straighter lines — a more modern, pared-down look. The IV also introduces complications not found in the II, including the moonphase (this model) and the BlueMoon (deep blue dial with gold moonphase).
How does this compare to the other Teutonia models City Chain carries?
City Chain carries three Teutonia families. The Teutonia II Small Second (M1-33-42-MB) is a classical dress watch with a midnight blue ray-cut dial and 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 on a white guilloché dial. The Teutonia IV Moonphase (this model) is the most romantic — a moonphase complication with blue lance-shaped hands on a clean, modern white dial. Choose by what you value most: classical tradition, daily information, certified precision, or poetic complication.
What are the blue lance-shaped hands?
The hour, minute, and seconds hands are coated in blue PVD and shaped with a pointed, lance-like profile — a design unique to the Teutonia IV. The blue matches the deep blue background of the moonphase disc, creating a deliberate colour connection between the hands and the complication. It's a distinctive detail that gives the Teutonia IV its own visual identity within the Mühle range.
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 the Teutonia IV Moonphase available on a bracelet?
Yes. The Teutonia IV Moonphase is available in three strap options: black crocodile leather with butterfly clasp (this model, M1-44-05-LB), blue suede leather, and a stainless steel bracelet with butterfly clasp. All versions share the same case, dial, movement, and moonphase complication.
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. Note: the moonphase display will also need to be re-set to the current lunar phase if the watch stops.
Is this a good gift?
Perhaps the most thoughtful gift in the entire Mühle-Glashütte collection. A moonphase is one of horology's most poetic complications — it connects the wearer to the natural world in a way that hours and minutes alone cannot. Combined with the blue lance-shaped hands, the white grained dial, the exhibition caseback, and the story of a six-generation German watchmaking family, this is a gift with emotional weight and genuine substance. An exceptional choice for weddings, anniversaries, milestone birthdays, and any occasion where the gift should carry meaning beyond its material value.
