COMPOSURE AND STYLE: Movado Bold TR90 is the tough new thermoplastic polymer material that gives the steel-core cases of these modern Movado BOLD designs their glossy, color-rich look and scratch-resistant surface. RESILIENT DESIGN: 42 mm black TR90 ion-plated stainless steel case with a black-toned dial on dark navy leather strap. REFINED SWISS ENGINEERING: Swiss quartz movement provides incredibly precise timekeeping, superior craftsmanship and minimal maintenance for a reliable and worry-free timepiece. EXCLUSIVE STYLING IN K1 CRYSTAL: K1 mineral crystal is the most common crystal used in designer watches and more scratch-resistant than regular mineral crystal. It's even more shatter-resistant than sapphire crystal. ON THE TOWN: Water resistant down to 3 atmospheres, you can rest assured that your watch will weather the conditions you put it through.
