I'm selling a wonderfully preserved Lucien Rochat chronograph, Royal Air model, all in solid 18 kt gold. Solid case with screw-down case back and crown, measuring 42 mm in diameter. With an indicated water resistance up to 10 ATM (100 m), but as it is a chronograph that is over 25 years old, it is not guaranteed to be watertight. Unidirectional rotating bezel in 18 kt gold. White mother of pearl dial with three sub-dials for small seconds, minutes and chronograph hours. Original Lucien Rochat bracelet, complete with spare links in 18 kt gold up to 20 cm. Original Lucien Rochat 7500 customised movement on Valjoux 7751 base, 17 jewels. All in perfect working order. Comes with original box and outer box.
