Incredible high end watch made by Gübelin. Automatic movement 4458306 Acier Inoxyable is labeled on the inside. The serial on the watch back is 4458306. It?s a small face and the only text on the back indicates it?s waterproof. This tells me that it was made prior to the FTC ban on the term waterproof so it?s approximately 1940-1968. It currently is fitted with an stretchy, stainless steel Speidel band. Value for these watches are all over the place. Some as high as $2500 and as low as $150. Our number was chosen semi-arbitrarily so feel free to make an offer! Ships via USPS AC Gubelin Women?s Watch Automatic Bumper Movement Self Winding WORKS! ca. 1950/60s. Condition is "Pre-owned".
