Vintage 1962 Nivada Grenchen Aquamatic | 17J, Automatic, Cal. AS3E
Up for sale is a rare, cleanly styled vintage 1962 Nivada Grenchen "Aquamatic" mechanical dress wristwatch. This Swiss timepiece features a striking matte black dial decorated with heavily applied gilt numerals, dagger indices, and a beautiful, authentic fine-grain age patina. Powering the watch is a copper-finished, factory-original 17-jewel Swiss Caliber A3SE automatic movement, co-signed by Croton and featuring the official wartime/post-war "COW" US market import code. The watch comes freshly paired with a brand new, premium Hadley Roma 17mm genuine Italian calfskin leather strap.
Condition:
Currently ticking, running, and winding smoothly both manually and via its automatic rotor mechanism. The unpolished 10K rolled gold plate case and lugs show normal surface scuffs and minor wear typical for its age, while the steel back retains deep text stampings. The original dial and hands are untouched, developing a beautiful, uniform fine-grain patina. Note a small hairline crack on the acrylic crystal near 10 o'clock, which does not affect structural integrity. Service history is unknown; timekeeping accuracy, power reserve, and water resistance are not guaranteed. Note on Photos: High-resolution close-up photography tends to overstate minor blemishes. Recent buyer feedback consistently highlights that our watches look much cleaner, smoother, and more exceptional in person and on the wrist than the photos suggest. Please review all gallery photos and video for more details.
