Overview
A compact Casio HS-70W-1JH stopwatch in black and silver, weighing 85 grams, built for coaches, referees or lap timers who want a dedicated handheld unit instead of a phone app.
Casio's HS series stopwatches are a long running, simple line rather than a new design, generally favored for one job done reliably at a low weight. The specs available here confirm only color and weight, not lap memory or split-time functions.

Who it's for
Fits coaches and timers who want a dedicated stopwatch that's quick to operate one-handed. Anyone who wants a stopwatch with app connectivity or GPS pace tracking should look at a fitness watch instead.
