Seiko Mechanical Stopwatch 88-5061 ACRP – Precision stopwatch with original box (April 1980)

Classic mechanical stopwatch by Seiko , made in Japan, model 88-5061 (ACRP) . This stopwatch comes from the professional timing line that Seiko developed in the 1970s and 1980s for sports and laboratory applications, among others.

The finely tuned mechanical movement offers a 1/5-second scale and a total measuring time of up to 60 seconds , with a small subdial for displaying minutes. The start, stop, and reset mechanism operates smoothly and precisely – a hallmark of Seiko precision instruments of that era.

The clean, matte silver dial with black scale and the brushed stainless steel case convey a classic instrument look. The distinctive pusher and the finely knurled crown ensure excellent usability.
