Type XX military chronographs began production in the 1950s. The “type” designation was not model-specific to any one brand, but rather a military specification commissioned by the French Government.

The requirement was for a multi-purpose wristwatch, suitable for both aviation and aerial navigation. The black dial on the present watch features three subsidiary dials, a robust 38.5mm case and rotating bezel. Intended for military purposes, it was fitted with luminous Arabic hour markers and luminous hands for quick and easy readability in darkness. It was a pleasure for our specialists to realize the material is original radium, and aged to a highly attractive sand tonality.

A superb watch in its own right, this particular Type XX is made even more special by its “Esso” engraving to the back. It was a relative common custom during the second half of the past century for corporations to request from brands custom watches – most often simply bearing the name of the company on the dial or, as in this instance, back; at times escalating to technical modifications such as the Sea-Dweller for Comex or the GMT-Master for PanAm, both of them Rolex efforts.

Research with Breguet indicates that the present watch was sold on November 24, 1957 to ESSO STANDARD for the price of 44,100 French Francs. Research has showed that Esso had previously bought watches for rallies that they sponsored, notably for the winner of the Monte-Carlo Rally in 1959. Phillips had also previously sold another Esso engraved example, owned by Sir Jack Brabham. Brabham was given his watch in 1960 after winning his first Formula One championship.

This example is an outstanding representation of a rare civilian 1960s Breguet, and one that will provide enduring value to the savvy collector. The superb condition, originality and customized caseback this watch boasts are sure to satisfy the demands of even the most refined collectors.
