Vintage kingston 17 jewels - Gem。BEAUTIFUL , NEARLY SCRATCH FREE FACE CRYSTAL ( FOR THE NAKED EYE) DESPITE ITS AGE. ‼️THE WATCH WINDS UP , BUT STOPS AFTER A SHORT PERIOD OF TIME & DOES NOT KEEP TIME! NEEDS DEFINITE CLEANING OR POSSIBLE REPAIR ‼️ ABSOLUTELY COULD BE WORN IN AS IS CONDITION JUST AS GORGEOUS PIN OR BROOCH OR EVEN POSSIBLY CONVERTED TO A PENDANT BY YOUR JEWELER BY ADDING A SIMPLE BAIL. STAMPED / HALLMARKED IN THE BACK 10K R.G.I. ( THAT IS WHAT IT LOOKS TO ME, YOU CAN JUDGE YOURSELF BY THE INCLUDED PICTURES), I AM UNSURE WHAT IT MEANS, HENCE NOT LISTING IT AS 10K GOLD, BUT AS A GOLDFILLED TO BE ON THE SIDE OF CAUTION. THIS IS A VERY RARE UNIQUE PIECE, VALUABLE NOT ONLY AS A WATCH, BUT MORE SO AS A VERY BEAUTIFUL PIECE OF JEWELRY.
