The Longines Conquest Ultronic Ref. 6332 is a fascinating example of 1970s watchmaking innovation. Housed in a bold stainless steel cushion case, this vintage piece features a tuning fork movement that hums at 300 Hz, producing a perfectly smooth sweeping seconds hand. Unlike traditional mechanical watches, there’s no ticking—just a soft hum that defined a short but legendary era in horology.
The silver-and-white bullseye dial with tritium blocks and sharp angular hands offers excellent legibility, while the day-date display at 3 o’clock adds practicality. With its mix of futuristic engineering and distinctly retro aesthetics, this Conquest Ultronic captures the experimental spirit of Longines during the early 1970s. Supplied with its original Longines bracelet, this is a collector’s piece that balances rarity with wearability.

Historical Significance
The Longines Ultronic series was born out of the brand’s experimentation with electronic technology in the early 1970s. Powered by tuning fork movements like the ESA 9164, these watches were positioned as highly accurate alternatives to traditional mechanical timepieces—bridging the gap before quartz dominance. Their distinctive hum and sweeping seconds hand still set them apart today.
With its bold cushion case, original bracelet, and futuristic tuning fork movement, the Conquest Ultronic Ref. 6332 is not only a vintage curiosity but also a milestone in Longines’ long legacy of technical innovation.
