Offered for auction is a striking Nivada Grenchen F77 Automatic Tiger Eye Bicolor, reference 68033A77, a modern reinterpretation of the iconic F77 sports watch originally introduced in the late 1970s. The F77 has become one of Nivada Grenchen’s most sought-after collections, renowned for its distinctive integrated bracelet design and strong vintage-inspired character. This particular version stands out thanks to its stunning natural Tiger Eye stone dial, whose golden-brown tones display a unique shimmering effect known as chatoyancy. Each dial is cut from genuine Tiger Eye stone, meaning every watch is naturally unique and impossible to replicate exactly. The elegant two-tone stainless steel and gold-coloured finish perfectly complements the warm hues of the dial, creating a sophisticated 1970s luxury sports-watch aesthetic reminiscent of the golden age of integrated-bracelet watch design. The octagonal bezel with exposed screws further reinforces the watch’s distinctive character. Powered by a Swiss automatic movement and protected by a double-domed sapphire crystal, the F77 combines vintage style with modern reliability and everyday practicality. ⸻ Specifications * Brand: Nivada Grenchen * Model: F77 Automatic Tiger Eye Bicolor * Reference: 68033A77 * Movement: Swiss automatic movement (Soprod P024) * Power reserve: Approx. 38 hours * Case material: Stainless steel with gold-tone accents * Case diameter: 37 mm * Crystal: Double-domed sapphire crystal * Dial: Genuine Tiger Eye stone dial * Bracelet: Integrated stainless steel two-tone bracelet * Water resistance: 100 metres (10 ATM) * Functions: Hours, minutes, central seconds * Swiss Made ⸻ Condition The watch is offered in excellent condition and functions correctly.
