Breguet is renowned for the guillochage on the dials of its timepieces, which create refined yet sober backgrounds that allow the indications to be read clearly and do not crowd out the off-set tourbillon on this piece. Like the 42mm diameter case, the dial is also in 18-carat gold and has been silvered and engine turned by hand. The Breguet Calibre 581DR that powers this piece at a frequency of 4Hz has a lateral lever escapement in silicon and anti-magnetic steel, a silicon balance spring, small seconds mounted on the tourbillon and a power reserve of 90 hours.
