Case and Dial Design

The Breguet Transatlantique Type XX is housed in a three-body stainless steel case measuring 39 mm in diameter. The exterior is characterized by a mix of polished and brushed finishes, featuring a distinctively reeded band. It is equipped with a bi-directional revolving graduated bezel, a screwed-down crown, and a screw-down case back to ensure water resistance. The watch is protected by a domed sapphire crystal. The black dial is designed for legibility with luminous Arabic numerals and steel dot indexes. It includes subsidiary dials for constant seconds, a 30-minute chronograph register, and a 12-hour register. A date aperture is positioned at the 6 o'clock mark. The time is indicated by luminous steel baton hands,

Movement and Mechanics

The timepiece is powered by the Caliber 582Q, a self-winding mechanical movement. This caliber features rhodium-plated plates decorated with fausses cotes. The chronograph mechanism is a fly-back type, operated by round push-buttons. The movement is constructed with 25 jewels and utilizes a straight-line lever escapement. Technical precision is managed by a monometallic balance, which has been adjusted to heat, cold, isochronism, and five positions. The system includes a shock-absorber and a self-compensating flat balance spring to maintain performance. The dial, case, and movement are all signed by Breguet, confirming the integrity of the watch assembly.

Condition and Provenance

According to the provided auction details, this lot was sold in August 2000. The watch is currently fitted with a Breguet stainless steel link bracelet that features a concealed deployant clasp. The total approximate length of the piece is 180 mm. The case is graded as '3-9', with some visible scratching noted. Conversely, the dial is described as 'as new', and the hands are confirmed as original to the timepiece.
