Angelus was founded in Le Locle, Switzerland, by the brothers Albert and Gustav Stolz, who shared a passion for precision and innovation in watchmaking. In 1898, Charles Stolz joined the company after qualifying as a watchmaker, bringing additional expertise and helping the family business expand its technical capabilities. Together, the Stolz brothers laid the foundation for a brand that would become renowned for its pioneering movements, exceptional craftsmanship, and contributions to the evolution of modern horology.

Just three years after founding Angelus, the Stoltz brothers secured their first patents for an “improved semi-instantaneous chronograph counter mechanism”. This early achievement highlights their remarkable drive for innovation from the very beginning. By developing more precise and efficient chronograph systems, the Stoltz family not only strengthened Angelus’ technical foundation but also set the stage for the brand’s future leadership in chronograph watchmaking.

One of Angelus’ earliest innovations was its patent for a “silent regulator for repeater watches”. The invention not only demonstrated Angelus’ dedication to solving practical challenges in watchmaking but also set the tone for the brand’s long-standing tradition of pioneering complex movements that combine functionality, reliability, and innovation.

Angelus (Stolz Frères) was awarded a gold medal for its pocket watches at the International Exhibition in Paris, a distinction that highlighted the brand’s technical excellence and refined watchmaking. This early accolade firmly established Angelus as a leading name in precision horology.

Angelus employed 15 people and had already specialised in high-end pocket watches featuring repeaters or chronographs, with its most sophisticated models combining both complications. Over the following decade, Angelus received numerous international accolades, further cementing its reputation for excellence. Highlights include a gold medal at the International Exhibition in Liège (1905), the Grand Diplôme d’Honneur in Milan (1906), and the prestigious Grand Prix at the Swiss National Exhibition in Bern (1914).

During the challenging times of the First World War, the Manufacture continued to innovate and produce meaningful timepieces. Among them was a specially designed pocket watch for visually impaired war veterans. These watches featured open dials without glass crystals, allowing the wearer to feel the position of the hands by touch. Available with a repeater function, they combined practicality with mechanical sophistication. This initiative earned Angelus a letter of gratitude from French Army General Marshal Joffre.

As repeater pocket watches gradually fell out of fashion, Angelus adapted to changing tastes by expanding its range to include table clocks and travel alarm clocks. Continuing its spirit of innovation, the Manufacture filed its first alarm clock patent in 1923, marking an important step in its development. Many of these timepieces were equipped with eight-day movements, combining practicality with the brand’s hallmark of long power reserve and mechanical reliability.

Angelus introduced its first wrist chronographs, marking a key milestone in the brand’s evolution. Early models featured mono-pusher (single-button) , particularly in larger cases, emphasising simplicity and functionality. At the heart of these timepieces was Angelus’ first in-house wrist chronograph movement, the calibre SF 15, showcasing the Manufacture’s growing expertise in precision chronograph engineering.

Angelus was awarded three 1st-class certificates by the Observatory Le Locle, one for accuracy and two for complications. Three years before, in 1926, Angelus earned its first award in the United States, a gold medal at the International Exhibition in Philadelphia.

Angelus crafted wristwatches with the world’s smallest eight-day movement (21×32 mm). This high-precision calibre, accurate to an astonishing ±1 minute per week, was also supplied to other brands, notably Tiffany & Co. Rare Angelus purse watches even featured this tiny eight-day movement.

Angelus launched its first two-pusher chronographs featuring 30- or 45-minute counters, establishing itself as a leading manufacturer.

Angelus introduced clocks featuring the world’s smallest eight-day alarm movement, the SF 240, at just 16’’’ size.

In response to the rise in worldwide travel during the 1930s, the brand introduced the innovative foldable Dateclock, which featured a full calendar on a separate display. In 1937, Angelus also produced the unique Foursome, an eight-day alarm clock that included four separate displays: a full calendar, a barometer, and a thermometer.

Angelus introduced the Chronodate, which was soon renamed the Chronodato. This innovative chronograph features a 45-minute counter and a complete calendar. Most models from this era were displaying four small red markers on the minute counter, representing units of three minutes, specifically designed for timing telephone calls. The Chronodato quickly gained global popularity and was available in a wide range of stunning designs. Its calendar movement, SF 217, is based on SF 215, which was originally produced in the 1930s. Ultimately, the Chronodato became Angelus’ most famous and best-selling watch.

The Angelus SF 215 movement, featuring a 45-minute counter, was also utilised in Panerai’s legendary military dive chronograph, the Radiomir Mare Nostrum, highlighting the calibre’s esteemed reputation. During the same period, Angelus continued to innovate in travel clocks by producing the Sixsome, a premium eight-day alarm travel clock featuring a separately displayed full calendar, barometer, thermometer, hygrometer, and compass.

Angelus introduced its new smaller chronograph calibre SF 250 (12’’’, 30-minute counter).

The calibre SF 250 powered the remarkable Chrono-Datoluxe, which was the first wrist chronograph to feature a digital date display. This was accomplished using two separate rotating date discs that also indicated the weekday and moon phase on the dial. Angelus also utilised the calibre 250 for calendar watches with a digital date display, but without a chronograph. This included the moon-phase version known as the Datoluxe and another version without the moon phase, called the Dato.

The hand-wound Angelus SF 240 calibre features an 8-day power reserve and is highly regarded for its long running time. Notably, Panerai started using it in its renowned military diver watches.

The Datalarm model was presented and was the first alarm wristwatch with a date. This model was produced over many years in various dial and case designs.

Angelus introduced the renowned waterproof Tinkler, one of the world’s first automatic wristwatches featuring a repetition function. This quarter repeater is activated by a pusher located at 9 o’clock. The innovative repetition module was created by Alfred Louis Golay for Angelus and was patented in 1958 and registered in 1960.

Angelus created several notable chronographs, among them a rare Doctor’s Watch featuring pulsation and respiration scales, as well as a magnifying section built into the crystal for easy reading. In honour of this unique piece, Angelus relaunched the Chronographe Medical in 2023 in a 99-piece limited edition.

Always leading the way in new technology, Angelus unveiled an innovative electric wristwatch powered by the Landeron 4750 calibre—the first Swiss electric calibre to feature a balance and Incabloc shock protection. During the same period, the brand also developed a captivating electric desk clock that includes a world time display, automatically updating the hour for every timezone.

Angelus released a remarkable 5-minute repeater wristwatch. Its repetition module, developed by Dubois Dépraz, is seamlessly integrated with the ETA 2801 movement.

Angelus eventually ceased production, though its alarm clocks were still advertised in 1979. The exact date of closure is unclear as records from that period no longer exist.

The renowned Swiss manufacturer La Joux-Perret acquired the Angelus brand to continue the innovative spirit of its founders into the 2010s. The company aimed to create a cutting-edge tourbillon collection using modern materials such as titanium, carbon, and sapphire. The first model, the Tourbillon Lumière, featuring an off-centred tourbillon, was introduced in 2015.

Angelus reconnected with its esteemed chronograph heritage through the Chronodate, a neo-retro chronograph that links its storied past to the brand’s forward-looking direction since 2015.

The La Fabrique collection was unveiled, introducing a vintage-inspired line inaugurated with the Chronographe Médical, while the Chronodate and Flying Tourbillon were featured in the modern L.A.B. collection.

Angelus achieved a significant honour at the Grand Prix d’Horlogerie de Genève by winning the Chronograph Watch Prize for its Chronographe Télémètre in yellow gold.
