Fortis Waterproof Swiss Made men’s wristwatch, dating approximately from the 1950s, featuring a charming black and cream two-tone dial, a configuration particularly representative of mid-20th-century Swiss watchmaking. The dial features applied gold-tone Arabic numerals alternating with geometric hour markers, a peripheral minute track, and elegant gold-tone hands with a distinctive vintage design. The natural patina that has developed over time on the lighter section of the dial gives the watch an authentic and unique character, particularly appealing in a timepiece of this age. Inside is a Swiss mechanical hand-wound movement with 17 jewels and Incabloc shock protection, signed Fortis. The watch was serviced in June 2026 and, on the same occasion, the case was re-chromed, giving it a particularly bright and well-preserved appearance.
