A refined and highly characteristic example of mid-century Swiss watchmaking, this Cortébert Grand Prix combines elegant 1950s aesthetics with one of the brand’s rarer and more respected manual-winding movements: the Cortébert Caliber 677. With its beautifully textured original dial, balanced proportions, and oversized dress-watch dimensions for the era, the watch perfectly reflects the understated sophistication of post-war Swiss horology. For its era, the watch was considered relatively large for a dress model, giving it a stronger wrist presence while still preserving the refined proportions expected from a classic vintage piece. Case: The watch features a slim gold-plated case with elegant elongated lugs typical of refined Swiss dress watches from the 1950s. The warm gold tone harmonizes beautifully with the silver dial and gilt handset, creating a highly balanced vintage appearance. The case shows honest signs of age and wear consistent with careful long-term use. * Case back: Stainless steel * Case thickness: Approx. 8 mm (including crystal) Movement: Powered by the very rare Swiss Cortébert Caliber 677, a high-quality manual-winding movement introduced in 1945. This caliber is appreciated among vintage collectors for its elegant architecture, reliability, and refined finishing. The movement reflects the robust mechanical philosophy of post-war Swiss watchmaking and remains visually attractive with its traditional bridge layout. * Movement type: Manual winding with 15 jewels * Caliber: Cortébert Cal. 677 * Frequency: 18,000 vibrations per hour (vph) * Power reserve: Approx. 41 hours * Antimagnetic Dial: The original silver-tone dial is undoubtedly the centerpiece of the watch. Its finely executed concentric guilloché-style texture radiates outward from the center, creating remarkable depth and light play across the surface. The sector-inspired construction gives the dial exceptional visual balance and elegance. Particularly striking is the outer chapter ring, where the applied faceted hour markers are positioned with superb symmetry. These elongated applied indexes create a refined architectural rhythm around the dial. Under changing light conditions, the alternating polished surfaces of the indexes produce subtle reflections that further enhance the dimensionality of the dial. The elegant gilt dauphine hands integrate harmoniously with the markers, while the recessed small seconds register at 6 o’clock reinforces the classical Swiss dress-watch aesthetic of the period. The dial is in good condition, but there is a small visible mark near the sub-seconds area, mentioned for full transparency. Crystal: Acrylic crystal Functions: Hours, minutes, and small seconds at 6 o’clock Crown: Original Strap: Fitted with a never-used genuine black leather strap. (Total length including watch: Approx. 25 cm) Dimensions: * Case diameter: 35 mm (excluding crown) * Case diameter: 37 mm (including crown) * Lug-to-lug: 40 mm * Lug width: 18 mm Condition: The watch is in very good overall vintage condition considering its age. The original dial remains especially attractive with balanced aging and preserved details. The movement clean and well-preserved. It runs smoothly, keeps good time, and is fully functional. All components are original except the strap and buckle. An elegant and increasingly collectible mid-century Cortébert, combining rare mechanics, oversized vintage proportions, and timeless Swiss dress-watch aesthetics.
