Stührling is known for luxury watches designed specially for the working man, carefully crafted with special attention to detail. Made from premium stainless steel and Kyrsterna crystal, Stührling uses reliable and efficient Japanese quartz movement technology. Stührling designer watches are striking enough to dress up your suit for a night on the town, yet functional enough to wear during sports activities the next day. Monaco watches are water resistant to 165 feet/50 meters. About the Watches Stührling's nylon bands are intended to hold up under strenuous use during sports and athletic activities. Most Stührling Original watches are equipped with a "pull out" crown with dual "O" rings, which will accommodate water resistance to one hundred meters. This is more than sufficient for most fine timepieces made for men's diverse daily activities. PLEASE NOTE: We do not recommend swimming or diving with your watch unless it has a screw-down crown (also known as screw-lock or screw-in crown) and is water-resistant to a minimum of 100 meters. Some of our timepieces meet this requirement, like the Regatta series (660 feet/200 meters), and are made to endure rougher and tougher wear, particularly in the diver's category.
