The Hamilton Otis Watch is a vintage rectangular wristwatch for men. It features a gold-filled case and gold bezel with a polished finish. The black dial has a 12-hour display and is complemented by a brown leather two-piece strap. The watch has a manual mechanical movement with 19 jewels and was manufactured in the 1930s in the United States. It comes with service records but without papers or original box/packaging. The watch has a lug width of 23mm and a case size of 40mm lug to lug.This is a great looking extremely rare Hamilton Otis watch that winds, sets, and runs well.  It was introduced in 1938, and had a very short production run,due to licensing issues with the LeCoultre "Reverso" which was introduced in 1931. It is therefore an extremely difficult watch to find, and to find one in good condition is even more rare. This has an engraving on the flip back of the case,. The case flips, and stays in place perfectly when wearing as well.
