IWC Cal. 89 dress watch, 1969
This 1969 IWC Schaffhausen reference 910 presents a restrained mid-century dress aesthetic in a 35 mm gold‑plated case with an original signed dial and period acrylic crystal. The hand‑wound IWC Cal. 89 movement, fitted here with 17 jewels, is a hallmark of the brand’s mid‑20th century watchmaking—valued for its straightforward construction and dependable regulation. Recently serviced (05-08-2025) and supplied on a leather strap, the watch offers an elegant, wearable example of classic Swiss finishing and movement tradition that suits a collector seeking authentic vintage proportions and mechanical character.
