Big, bold numbers, and now a big bold strap comes on Nixon's 51-30 Chrono Leather Watch. The 51-30 Chrono Leather has the great functionality and design of the normal 51-30 Chrono, but with an imported leather band and a stainless steel buckle. Nixon includes 6 hand Japanese quartz movement with a second, date, and time dial, custom 300 meter stainless steel case with hardened mineral crystal window, and a screw crown at the 9 O'Clock position.
