This 1970s Jaeger-LeCoultre Master-Quartz 23303-42 combines innovation and timeless design. Equipped with the quartz calibre 352 developed by Girard Perregaux in the early 1970s, it was one of the first quartz watches and a symbol of the breakthrough precision of quartz technology at the time.
The anthracite-coloured dial with its distinctive "buzz saw" pattern gives the watch a unique texture and depth. The subtle transitions between lighter and darker tones create a dynamic yet elegant appearance. The generous 38 mm case gives the watch a modern presence.
The quartz calibre 352 is based on the 1960s Beta-21, but has a higher frequency of 32000 Hz compared to the Beta-21's 8000 Hz, making it more precise. At the same time, it was possible to limit the height of the movement, which made the calibre popular with other watch brands.
This Jaeger-LeCoultre is ideal for watch enthusiasts and connoisseurs who appreciate the symbiosis of technical progress and 1970s design.
