stopwatch
A timepiece designed to measure intervals of time.
If it looks like a pocket watch, do not tag it as a stopwatch unless the large face numbers in seconds rather than hours (rare if exists on Danbooru). Stopwatches measure time elapsed rather than telling the current time, though some devices may be able to do both.
