Bulova Accutron 'Brown Fumé'

Few watches capture the technological optimism of the 1960s and ’70s quite like the Bulova Accutron. Introduced in 1960, the Accutron replaced the traditional balance wheel with an electronically powered tuning fork, creating the characteristic hum and remarkable accuracy that made it one of the defining horological innovations of the pre-quartz era.

Dating to circa 1973/1974, this Accutron is particularly interesting for what is inside. Its Calibre 2210 belongs to Bulova’s tiny 221 family, introduced in 1973 and regarded as the smallest tuning-fork watch movement ever put into production. Operating at an unusually high 440 Hz, the miniature mechanism was developed primarily to allow Bulova to create smaller, slimmer watches. In a wonderfully counterintuitive move, the company also installed it in larger men’s models such as this one, using a spacer to accommodate the diminutive movement.

The watch itself is pure 1970s. Its gold-plated case has a softly rounded, almost cushion-like profile surrounding a beautifully graduated brown-to-champagne sunburst dial. Applied block hour markers, simple luminous hands, a peripheral minute track, and the Accutron tuning-fork emblem at 6 o’clock give the dial a clean, almost futuristic quality. There is no seconds hand or date display to interrupt the design.

Fitted to a gold-tone expandable bracelet with a signed deployant clasp, this Reference 2210 represents an especially fascinating moment in watchmaking: mechanical horology was being challenged by electronics, while quartz was waiting just around the corner. The technology may have been transitional, but the result is anything but forgettable. A tiny 440 Hz tuning fork humming away inside a big, unapologetically 1970s gold watch.

Joseph Bulova, a Czech immigrant to the United States, founded his eponymous company in Queens in 1875, opening a factory in Biel, Switzerland in 1912 to mass-produce timepieces under the American production model. An early designer of men’s wristwatches following their widespread adoption in the wake of the First World War, the firm developed simple dress watches, dive watches, and chronographs through the first half of the 20th century.

As the decades wore on, however, the limitations of the traditional oscillating balance wheel — both with respect to accuracy and robustness — were becoming apparent. Electric watches from the likes of Hamilton and Lip experimented with a moving coil motor in place of a mainspring, but their reliance on conventional balance wheels meant they were little more accurate than their entirely mechanical counterparts. A Swiss engineer at Bulova named Max Hetzel would soon change all that.

A born tinkerer and a brilliant mind, Hetzel adopted an old clock design from the 19th century — incidentally invented by the grandson of Abraham-Louis Breguet — that used a tuning fork as its oscillator. Powered by a dry-cell battery and driven by an electromagnetic coil, its frequency of 360 Hz ensured a highly accurate system that powered a sweep hand around the dial. Significantly more accurate than a mechanical design, it was patented in 1953, and after some years of work, the Bulova Accutron debuted to the public in 1960.

The watch was a revelation — literally. A 1961 model with a transparent dial meant to show authorized dealers its inner workings became so popular that Bulova put it into regular production, calling it the Spaceview. Meanwhile, the audible 360-Hz hum produced by the movement was a novel selling point, featuring in period advertisements in which a man was seen holding the watch up to his ear.

When the U.S. government sought to replace the U-2 spy plane with an aircraft that could outmaneuver anti-aircraft systems, Lockheed Martin’s secretive Skunkworks division offered the perfect solution in the form of the sleek A-12, which could reach speeds of Mach III (~2,310 mph). Bulova Accutron wristwatches accompanied the pilots of this advanced piece of engineering, as they did on the wrists of public-facing X-15 flights, which reached speeds of 4,500 mph. The Accutron was even worn by astronauts during the Mercury Seven program during training; in 1963 during Project Mercury; and in Project Gemini missions up until 1983, long after the tuning fork technology had been replaced by more contemporary quartz-powered tech.

In 2020, Accutron was spun off by parent company Bulova — owned by the Citizen Group of Japan — into its own brand, where it continues to produce modern versions of one of the world’s downright coolest watches.
