Introduced in 2015, the Boy Friend puts a slightly more masculine spin on the Première. The first major development came in 2018, when it was fitted with Calibre 3, a skeleton movement and Chanel’s third in-house Haute Horlogerie calibre. Three years in development, it was designed to be as beautiful from the front as from the back: components are vertically arranged in three overlapping circles that complement the Boy Friend’s rectangular case. This light-as-air impression is accentuated on this 100-piece limited edition by the sapphire case, which is fitted on an alligator pattern, black calfskin strap that fastens with a white gold triple folding clasp. Five baguette-cut diamonds are set on the crown.
