Overview For sale from my personal collection is a vintage Festina Extra jumbo dress watch from the 1950s, produced during Festina’s historic Swiss period in La Chaux-de-Fonds. The highlight is its large 37.6mm solid 18K rose gold case, an unusually generous size for a mid-century dress watch. It wears with strong presence while retaining the slim, elegant profile of classic 1950s Swiss watchmaking. The watch features an original unrestored silver/champagne dial, applied rose-gold numerals and indices, a domed acrylic crystal, and a manual-wind Felsa Caliber 390 movement. Dial & Aesthetics The original dial has developed attractive vintage patina, with fine speckling and light age-related marks consistent with age. The dial has applied rose-gold Arabic numerals at 12, 3, 6, and 9, faceted dagger-style hour markers, and matching rose-gold dauphine hands. At 6 o’clock is a recessed subsidiary seconds register with concentric circular graining.
