Mother's Day weekend is just around the corner but there's still time to look for a gift. A watch is always a good way to go, especially if she's a fan of fine watchmaking that marries superlative form with function. It's a gift that keeps on giving since it can be an heirloom to pass down to her daughter or granddaughters. Check out these offerings from Cartier, Baume & Mercier, Hermès, Piaget and Jaeger-LeCoultre, fresh off Watches & Wonders 2020.
