The Tissot PRS 516 Chronograph watch for men features a 42mm stainless steel case with a black bezel and a blue dial. This luxury sport watch has a Swiss quartz movement, date indicator, small second, and chronograph functions. The wristwatch also has a transparent sapphire crystal, water resistance up to 100m, and a tachymeter bezel. The watch runs well, keeps time and is in great condition however I changed the battery and now I cannot put the case back back on this should be an easy fix.
