Casio W-S220
Stopwatch with 120 Lap Counter, Dual Timers with Repeat Count, World Time, 5 Alarms (one Snooze Alarm), Nov. 2013

The back has a fine linear Satin brush finish and
another thing I observed, there is a grove around the elevated part of the case back. I had not noticed this before on any of my Casio case backs. And believe it or not, the tiny harilines on the right are from my dry skin. I had been working and cleaning and rearranging my study. Leaving me with drier skin then usual. And these tiny hairlines where from my thumb removing the general importer's sticker on the case back. But there is not to worry. Any case back will eventually show hairlines. Because our wrist hair has very sharp edges that will cause hairlines over time.
