Description

The H. Moser & Cie. Pioneer Tourbillon Concept Aventurine, reference 3804-0902, has been created as an exclusive collaboration with Bucherer, embodying a fusion of contemporary engineering and minimalist aesthetics. Crafted from a combination of 18k red gold and DLC-coated titanium, the 42.8 mm case has been meticulously finished to balance durability with refined elegance. A striking aventurine glass dial has been introduced, evoking the vastness of the night sky with its shimmering deep-blue surface, uninterrupted by logos or indices in adherence to H. Moser & Cie.’s signature “concept” design philosophy.

At the heart of this timepiece, the in-house Calibre HMC 804 has been placed, offering automatic winding and an impressive 72-hour power reserve. A one-minute flying tourbillon has been positioned at six o’clock, showcasing the brand’s technical mastery while enhancing timekeeping precision. A bi-directional rotor, crafted from solid gold, has been integrated, ensuring efficient energy transmission with each wrist movement. Operating at 28,800 vibrations per hour (4 Hz), the movement has been engineered for both performance and reliability.

A domed sapphire crystal protects the dial, while a transparent case back has been applied, allowing an unobstructed view of the movement’s exquisite finishing. Designed for versatility, the watch has been constructed with an impressive 120-meter water resistance, making it one of the rare tourbillon-equipped timepieces suitable for active lifestyles. A black rubber strap, secured with a matching red gold pin buckle, has been selected to enhance comfort while reinforcing the watch’s modern aesthetic.

This limited-edition release of only 18 pieces has been carefully curated for collectors who appreciate both horological innovation and understated luxury. The Pioneer Tourbillon Concept Aventurine stands as a testament to H. Moser & Cie.’s commitment to artisanal craftsmanship and avant-garde design.

H. Moser & Cie – bio

H. Moser & Cie was founded by independent watchmaker Heinrich Moser in St. Petersburg, Russia in 1828. Notable early clients of H. Moser & Cie included Russian princes and members of the Russian Imperial Court; Vladimir Lenin also owned a Moser watch. After Moser died in 1874, the company was sold, and its business in Russia was expropriated in 1918 due to the October Revolution.

In 1953, H. Moser & Cie continued its business in Le Locle, Switzerland where it shifted its focus from pocket watches to wristwatches. Due to the quartz crisis, H. Moser & Cie became a part of the Dixi Mechanique Group and the original brand name was dropped. In 2002, Moser Schaffhausen AG was founded by Dr. Jürgen Lange together with Heinrich Moser’s great-grandson Roger Nicholas Balsiger, and the brand H. Moser & Cie was formally re-launched in 2005.
