According tomedia New Atlas, The Swiss high-end watch maker Jaeger-LeCoultre has released two expensive ultra-small watches, Snowdrop and Bangle, using a 91-year-old mechanical movement that is still the smallest in the world.
This miniature manual upper-chain Calibre 101 mechanical movement was unveiled as early as 1929 and weighs just over 1 gram (0.035 oz) and measures only 14 x 4.8 x 3.4 mm (0.55 x 0.2 x 0.13 inches). At the time, brain surgery was 15 years away from the “ice cone therapy” phase.
For 91 years, the company has continued to manufacture the Calibre 101 movement, and no one has been able to make a smaller movement. As a result, it is not only the smallest watch movement in the world, but also one of the oldest movements still in production.
The company’s two newest watches, Snowdrop and Bangle, use this mechanical movement. The former has some 904 diamonds inlaid on two gold straps, for a total of 20.9 carats, while the latter has 996 diamonds on an asymmetrical strap, for a total of 19.7 carats.
The family plans to produce only a few dozen of these watches a year, with the aim of “adding to the light of outstanding women’s wrists”.
