Vintage Gruen Precision manual-wind wristwatch, recently fully serviced and ready to wear. This classic mid-century piece features a silver dial with applied gold numerals and markers, dauphine hands, and a gold-tone case with elegant curved lugs.

The movement has been completely disassembled, cleaned, lubricated, and adjusted. It is currently running approximately –25 to +25 seconds per day, with ~210–250° amplitude and 1.1–1.2 ms beat error, which is within an acceptable and wearable range for a vintage mechanical watch. Please note that accuracy on vintage watches can be affected by factors such as position, wear habits, and shipping, and timing may vary slightly after transit.

During service, case gaskets were replaced, the acrylic crystal was polished, and the case was lightly polished to preserve original lines and character. The watch winds smoothly, sets correctly, and keeps consistent time in daily use. Fitted with a black leather strap, as shown.

Caseback is marked Waterproof / Shock Resistant / Anti-Magnetic per period standards; however, water resistance is not guaranteed, and this watch should be treated as not water resistant, as is typical for vintage timepieces.

A well-serviced, honest example of a vintage Gruen Precision — ideal as a classic daily wearer or addition to a collection.
