An anniversary premiere for sleek wrists.

Following decades of devotion to bigger is better, downsizing the diameter of watches has been a growing trend over the past few years, spurred by the fashionable reissuing of models from the archives. But this fashion trend is also progressive — tiny watches by today's standards are no longer exclusively reserved for ladies' wrists.

For instance, miniature Cartier Tank watches have been spotted on the wrists of rapper Tyler, the Creator and basketball player Dwyane Wade. Ladies aren't being left behind either, so Michelle Yeoh seen wearing an imposing watch by Richard Mille on the red carpet is probably more of an outlier in this regard.

Jaeger-LeCoultre marked the beginning of fall by launching a novelty in their High Jewellery 101 Secrets: a new collection equipped with Caliber 101. The movement, which is five years away from celebrating its centenary, is back in action.

It's 14 mm long, 4.8 mm wide, and measures 3.4 mm in height. The movement comprising 98 components has a 33-hour power reserve. Another interesting stat: it takes 40 hours to assemble this miniature watch engine. The manufacture has chosen to house this famous movement in their 101 Secrets watch. It debuted last year in rose gold.

Now the watch is available in platinum, but it won't be easy to get a good look at the case material. That's because the entire surface is encrusted with diamonds. The bracelet and case measuring 29.07 mm in length, 12.22 mm in width, and 9.88 mm in height are encrusted with 1,028 brilliant-cut stones, weighing a total of 26.21 carats.

The gem-setting alone takes the masters at Métiers Rares 182 hours of work. Another challenge is posed by working with platinum — a material which is twice as hard as gold.

But it was worth the extra effort: using this material provides the diamonds with additional backlighting. The novelty doesn't reveal all its secrets at  once: the dial is covered, and only unveiled when a diamond-set button is pressed and held down.
