"Ebana 20 Rubis Super Shock Resist Art-deco Men's Vintage Wristwatch Serviced"
A vintage Ebana 20 Rubis Super Shock Resist Antimagnetic Wristwatch. This mechanical wristwatch incorporates 20 jewels, and its dial prominently displays "Super Shock Resist" and "Antimagnetic" properties, which are features commonly found in vintage mechanical watches engineered to enhance durability and accuracy. The watch is identified by the "Ebana" brand name, and the "20 Rubis" designation refers to the 20 synthetic jewels strategically placed as bearings within the watch's mechanical movement, serving to minimize friction and wear. The "Super Shock Resist" feature denotes a shock-absorbing mechanism designed to safeguard the delicate balance staff from potential damage caused by impacts. Concurrently, "Antimagnetic" signifies the watch's resistance to magnetic fields, which are known to adversely affect the precision of timekeeping. Given the "Rubis" indication, the watch operates on a mechanical movement, with a manual-winding, consistent with watches produced in the mid-20th century.
