Blancpain 1735

The 1735 is a complication watch by Blancpain.

The "1735" by Blancpain, named after the foundation year of the manufacture, was presented at the end of 1990 at international press conferences. It combined all complications known to date in one single watch. It had an ultra-thin movement, a perpetual calendar with moon phase indicator, a rattrapante chronograph with split-seconds, a tourbillon and a minute repeater.

It was one of the most complicated and with its platinum case also one of the most expensive wristwatches of the earth.
