B66 Day Date
The B66 Day Date is built to take a beating and keep moving. The 43mm stainless steel case with titanium PVD coating feels tough without being heavy, and the grey dial keeps it clean and low-key. Bold hands loaded with Super-LumiNova X1, along with Lüm-Tec's MDV Luminous Technology for markers and indices, make it easy to read anytime. Powered by a Miyota quartz movement and rated to 200 meters, this is the watch you throw on when you need something you can actually count on.
