【ROLEX Ref.6427 / Oyster Precision / Engine-Turned Bezel / Champagne Dial】 Ref. 6427 is a representative model of the hand-wound "Oyster Precision" that appeared in the late 1960s. The movement is equipped with Cal. 1225, boasting Rolex's signature robustness and stability. Without an automatic winding mechanism, the structure is very simple, making it durable and easy to maintain. It is a practical movement with high accuracy, within ±10 seconds per day, and relatively inexpensive overhaul costs due to the fewer parts. The feature of this particular piece is the engine-turned bezel that delicately shines when exposed to light. It sits between the elegance of a smooth bezel and the flamboyance of a fluted bezel, exuding a unique presence while remaining classic. The dial has a warm champagne gold tone due to aging, and the bar indexes and silver hands give a sophisticated impression. The case and bracelet have minor scratches commensurate with their age, but are in good condition, allowing you to enjoy a vintage feel. The bracelet (7205) and flash fit (60) are consistent with the manufacturing year and maintain originality. Overhauled in October 2025, it operates comfortably for daily use. 【Specifications】 Model: ROLEX Oyster Precision Reference: 6427 Caliber: Cal. 1225 (Hand-wound, Non-Chronometer) Frequency: 18,000 / hour (5 vibrations / second) Case Material: Stainless Steel Crystal: Acrylic Bezel: Engine-turned Dial Color: Champagne Gold Case Diameter: 34mm Bracelet: 7205 (Riveted Bracelet) FF: 60 Serial: 274530 (Estimated Year of Manufacture: Around 1969) Overhaul: October 2025 Daily Rate: Within ±10 seconds Accessories: Box Dial Color...
