About this reference
The Blancpain Villeret Extraplate 6651N-1142-55B places its restrained dress vocabulary in a 40 mm stainless-steel case. An opaline dial, alligator-leather strap and see-through back keep the presentation elegant and legible, while the date adds everyday usefulness without disturbing the clean balance of the display.
Behind it, Blancpain Calibre 1151 is an automatic movement with a two-barrel architecture and a 100-hour power reserve. Its 27.4 mm diameter and 3.25 mm height suit the watch's slim profile; a free-sprung balance with silicon hairspring beats at 3 Hz. The central rotor, fine finishing, 28 jewels and 210-part construction make the movement as considered as the dial.
