New in Box Movado Elegant Black Watch

So this listing is Movado watch with cautionary notes - I was given authenticity warranted but despite this I cannot guarantee authenticity. The watch has sat in this box for 15 years - never worn, never taken out. Original Movado Watch with authenticity card and date of purchase. Never even taken out of box. Purchased in Bridgetown from International Jewellers on November 2010. Saying this - don’t know if it works! Likely requires battery change. Always kept I take on box despite this the jewelry case is fragile - likely due to poor fabric choice for box - it is like a soft vinyl - I would expect higher quality finishes but it is what it is. I absolutely have no idea of how much to sell for. International Jewellers should be a reputable company but knock-offs are everywhere. . Chic black box with Movado logo. Price was a $609. Special at time - they were listed for $1500. Plus duty fees, taxes ect.
