Helbros Gold Wristwatches | eBay。10K Rolled Gold Watch Vintage Needs some polishing Belonged to my mom, but hasn’t been worn in many years. You’ll need to have it checked by a jeweler. A watch manufacturer founded in Germany in 1913. The brand name is said to have been derived from the initials of the founders, the Helbein Brothers. In 1946, Helbros Watch Co. Inc. was established in New York, and as an American établisseur, it outsourced watch manufacturing to Germany, Switzerland, France, and other countries, and sold them in the United States. The products themselves seem to have been produced in highly reliable factories, and many of the watches are still in good working order today.
