Purchased during my single days and stored at home unused since giving birth. I bought it a while ago, so my memory is hazy, but it worked fine when exposed to sunlight, so I believe it's a solar-powered watch. Please note that since it has been stored at home in the shade, I cannot guarantee it will be working upon delivery. *For peace of mind, I recommend checking it at a watch retailer. How about it for someone who enjoys wearing it as an accessory? It's a design that suits formal occasions. An analog watch with black and silver stone embellishments. - Brand: Rubin Rosa - Color: Black/Silver - Features: Stone embellishments - Band Material: Stainless steel Thank you for viewing.
