Cortebert Cal. 307 Square Men's Watch, 1970

A matte white Roman-numeral dial sits within the sharply edged steel case of this 1970 Cortebert, reference 268.508P. The men’s watch has a clean two-hand display, a 29 mm case width and hand-wound caliber 307, based on Peseux 7050. New dark brown croco-pattern leather adds warmth to its otherwise monochrome presentation.

Roman numerals and a clean two-hand display

Printed black Roman numerals contrast clearly with the matte white dial. A discreet minute track follows the inner perimeter, giving the display a scale without filling the center. Cortebert is placed below 12, with Incabloc above 6.

The slim dark hour and minute hands follow the dial’s black-and-white color scheme. There is no date window or seconds hand. That time-only layout leaves the numerals and rectangular frame to define the watch’s appearance, while the Incabloc inscription adds a specific mechanical detail.

Brushed rectangular steel case

The stainless steel case of this vintage dress watch measures 29 mm wide and 38 mm from lug to lug. Flat brushed planes, straight edges and squared corners make its outline distinct from the round dial formats often associated with dress watches. A slim bezel keeps the white display open.

The small crown is proportionate to the case, and a plain brushed back continues the exterior’s restrained finish. The full 38 mm span is important when judging wrist coverage: the 29 mm width alone does not describe the complete footprint.

The new dark brown leather strap has a crocodile-pattern finish and fits the 19 mm lug opening. Its warmer tone contrasts with the steel and white dial, softening the visual effect of the straight case lines. The strap is a replacement accessory, separate from the original watch-head components.

Cortebert 307, based on Peseux 7050

Cortebert caliber 307 is a manual-wind movement based on Peseux 7050. It powers the hour and minute display and is wound by hand. The dial’s Incabloc marking refers to shock protection.

The watch is used, fully serviced and fully operational, with the original watch-head components retained. It comes with a 12-month warranty.
