Obituary: René Beyer, Owner of the World’s Oldest Watch Store

The man behind Beyer Chronometrie on Zurich's Bahnhofstrasse.

René Beyer, the eighth-generation owner of Beyer Chronometrie in Zurich, died suddenly on April 13, 2025, at the age of 61​. Beyer was a towering figure in Swiss watchmaking circles, known not only for helming his family’s 260-year-old business, but also for his passionate stewardship of its famed clock and watch museum, his warm ties with independent watchmakers, and his family’s close relationship with Patek Philippe. He is survived by his wife. Beyer’s passing was first reported by Zurich newspaper Inside Paradeplatz.

Born in 1963 into the Beyer dynasty that began in Germany in 1760, Beyer grew up surrounded by clocks and watches. Like his father, Theodor “Teddy” René Beyer, he qualified as a watchmaker himself​, learning the business from the ground up.

Beyer’s role in the family business started in 1986 when his father suffered a heart attack and was forced to step back. A decade later, Beyer had formally taken over as managing director and proprietor of Beyer Chronometrie, becoming the eighth generation to run the venerable retailer​, which first opened in Zurich in 1822. Unlike many of its peers that expanded nationally and internationally, the business remained a local operation in Zurich. Like many watch retailers of the old-school, Beyer was synonymous with his store.

A retailer and curator

During his nearly three decades at the helm, Beyer carried on his father’s legacy and bolstered the business’s reputation as a mecca for watch enthusiasts. In 2011, Beyer opened a mono-brand Patek Philippe boutique (the brand’s first retailer-managed boutique in Switzerland) underscoring the close relationship he enjoyed with the Stern family. 

The evidence of this close relationship, which goes back decades, can be found in the many ‘double-signed’ Patek Philippe watches that also carry the Beyer name.

Beyer was equally a champion of independent horology and historical clocks and marine chronometers. His father Teddy had forged a personal friendship with George Daniels, and acquired three pieces that are now on display in the Beyer Museum, alongside work from the likes of Breguet and Ferdinand Berthoud.

In 2022, Beyer began planning for the company’s future without him in charge of daily operations. He brought in Hanspeter Pieth, a seasoned luxury retail executive from Lucerne-based rival Gübelin, to assume the role of CEO in early 2023​. About a year later, René’s younger sister, Muriel Zahn-Beyer, rejoined the firm’s leadership and was named co-managing director.

Beyer was a lifelong ambassador for fine watchmaking, and his death has come as a shock to the industry. Given his life’s work, he would no doubt wish to see the family business live on. Ownership of Beyer Chronometrie evidently passed to his widow, and Ms Zahn-Beyer is managing operations. 

The situation is not unlike that of Jörg Bucherer, one of Beyer’s contemporaries who ran his own family’s eponymous retail empire. Bucherer passed away in 2023 with no heirs to carry on the family business. Knowing what was at stake, Bucherer sold the family firm to Rolex shortly before his death. Some in the Swiss media have wondered whether a deep-pocketed luxury group will step in similarly to take over Beyer Chronometrie.

Audemars Piguet’s New Ceramic is the Same Hue as the Royal Oak 5402

A dark blue tinged with black.

Bleu Nuit, Nuage 50” was the colour code for the original Royal Oak “Jumbo” ref. 5402 ST of 1972, and now Audemars Piguet has translated the dark blue shade into its latest ceramic. Making its debut in three Royal Oak models, including the Royal Oak Double Balance Wheel Openworked, the “Bleu Nuit, Nuage 50” ceramic is restrained and a departure from the bright, almost electric blue of the brand’s earlier blue ceramic.

Initial thoughts

Ceramic is a material that lends itself well to the Royal Oak design; the brushed and polished surfaces that are the trademark Royal Oak surface finishing look good with the hardness and glossiness of ceramic. The earlier bright blue ceramic used by AP was too bright in my opinion. The new dark blue hue, on the other hand, feels just nice.

The downside of an all-ceramic Royal Oak is the price. The Royal Oak Offshore Chronograph with a matching ceramic bracelet costs almost US$90,000, double the price of the steel equivalent and almost as much as the gold model.

According to AP, the cost is primarily due to the difficult in finishing the ceramic – every element of the case and bracelet is brushed or polished by hand – which is true, but it’s still expensive.

The most affordable model with the new ceramic only has its bezel and pushers in ceramic

” Night blue”

According to AP, “Bleu Nuit, Nuage 50” (which translates as “night blue, cloud 50”) was the code for the dark blue, almost grey, in the catalogue of Stern Freres, the Geneva dial maker once owned by the family that owns Patek Philippe.

AP explains that obtaining the colour back then was actually a two-part process: the dial was first treated in night blue before black pigment no. 50 was added to clear varnish (creating a “cloud” in the liquid) that was then applied over the blue, creating the distinctive blue-grey finish.

The colour was reproduced in the modern-day Royal Oak “Jumbo” ref. 16202, but with physical vapour deposition (PVD), an efficient process that delivers more consistent results. Now the shade has been reproduced in ceramic, with dark blue ceramic becoming the latest colour to join AP’s stable of ceramics that include also include customary black and white.

The most technically interesting model in the new ceramic is the Royal Oak Double Balance Wheel Openworked 41 mm. While having been in the AP catalogue for some time, the Double Balance Wheel remains notable for being a chronometry-oriented Royal Oak thanks to its concentric, mirrored balance wheels under a gilded bridge.

This is entirely in dark blue ceramic, with a dark blue flange around the skeletonised movement to match. It’s powered by the cal. 3132, which has a shortish power reserve of 45 hours, explained in part by the energy required to oscillate the additional balance wheel.

Also entirely in ceramic is the Royal Oak Offshore Selfwinding Chronograph 42 mm, which joins the existing model that’s all in black ceramic.

This takes after the original 1993 Offshore in size and style, though the dial has been tweaked, but is equipped with the in-house cal. 4404, an integrated chronograph movement with a flyback function.

And the most affordable model in the line up is the Royal Oak Offshore Selfwinding 43 mm, which contains the least ceramic. This has its bezel, crown, and pushers in dark blue ceramic, while the case is stainless steel.

It’s powered by the cal. 4401, a variant of the calibre found in the Offshore 42 mm above. The movement similarly has an integrated, flyback chronograph.
