1735 panel
In 1991, Blancpain created the world's most complicated self-winding series-made wristwatch, the "1735". Discover the 744 components of this highly complex timepiece, which features a minute repeater, tourbillon, split-seconds chronograph, moon phases, perpetual calendar and automatic winding. The assembly of the 1735 is so complex that only a handful of watchmakers in the world are qualified for this task, which requires a full year of hard work.
