Women's CARAVELLE watch case with mechanism. The weight with the inner mechanism is approximately 6.65 grams, without the internal works the case weighs around 3.45 grams. Outside is stamped 14kt gold case CARAVELLE N2 and on the inside below the mechanism it has the following numbers 2882 with 82 below. I think the N2 on the back is the year of production, 1972 but I can't be 100% certain. I'm sure whoever buys this piece will most likely know significantly more than I do about the items specifics. I do NOT know if the internal timekeeping mechanism actually works and frankly for the list price, IF it does work it would simply be an added bonus. Please don't hesitate to contact me with questions about this listing or any of my other items.
