Our take on the Seiko 5 Sports SRPK31 Watch

The Seiko 5 Sports SRPK31 is a 38mm automatic field-style watch, a smaller case size than the 42.5mm Seiko 5 Sports models it sits alongside. It runs on Seiko's 4R36 automatic movement with day-date, and its compact round case suits wrists that found the larger Seiko 5s too big. The best new price is $280 at Time Square Clock Shop as of November 6, 2026, with two stores listing it new.

Questions and answers

How does the SRPK31 differ from other Seiko 5 Sports models?
It uses a 38mm case, smaller than the 42.5mm cases common in the Seiko 5 Sports line. The movement and general styling stay in the same family.
Is it a good first automatic watch?
Yes. It is affordable, has a day-date display and a simple field-watch look. Expect to set the time again if you leave it unworn for a couple of days.
Does it have a sapphire crystal?
No. At this price Seiko fits a mineral crystal, which resists scratches but less than sapphire.
Is the 38mm case too small for men?
It is a matter of taste. 38mm reads as a classic, understated size and suits many wrists, but people used to 42mm or larger may find it small.
When is the best time to buy it?
The best new price is $280 at Time Square Clock Shop as of November 6, 2026. Watch prices move with sales events, so compare the two new listings before buying.

At Time Square Clock Shop, for $280.00, as of our latest check.
