Built big because the job demanded it. At 46mm across and 18mm thick, the #JSAR carries the proportions of a watch designed for fast reading, positive handling, and hard use. A high-torque ETA F07 quartz movement drives the oversized handset, while the 316L stainless steel case, sapphire crystal, screw-down crown, and 30 ATM water resistance give it the durability to keep moving well beyond the water. That same utility translates easily to dry land. Behind the wheel. Along a fence line. Through the day’s work. Large, legible, accurate, and ready when you are. That’s the Jumbo Diver’s Quartz.
