The Seiko 5 Sports SRPK37K1 is the Honda Super Cub limited edition built for Seiko 5 Sports’ 55th anniversary line. It keeps the familiar SKX-inspired sports case—about 42.5 mm stainless steel, unidirectional bezel, day-date, Hardlex crystal—then dresses it in a blue dial and Super Cub–branded nylon strap. Inside is Seiko’s calibre 4R36 with manual winding and hacking seconds.
Seiko produced this Super Cub reference as a limited run of 7,500 pieces, with limited-edition marking on the case back. The design language nods to the motorcycle’s lamps and graphics on the dial side, while the strap carries Super Cub and Honda logo details. Water resistance is 100 metres: fine for swimming and daily wear, not a certified professional dive watch.
Why collectors look at the SRPK37K1
- Honda Super Cub collaboration: blue dial and themed nylon strap aimed at Seiko 5 and motorcycle fans.
- Limited edition: 7,500 pieces with limited engraving on the case back.
- Calibre 4R36: automatic, hand-wind, hacking, 24 jewels, about 41-hour power reserve.
- Sports case geometry: about 42.5 mm diameter, 13.4 mm thick, roughly 46 mm lug-to-lug, 22 mm lugs—same family as many modern 5 Sports “SKX-sense” models.
- Day and date at 3 o’clock plus a unidirectional elapsed-time bezel.
- Hardlex crystal and luminous hands/markers for everyday readability.
- Nylon strap: lighter on the wrist than a full steel bracelet; easy to swap on 22 mm lugs.
Who it suits
Anyone searching for Seiko SRPK37, SRPK37K1, or a Seiko 5 Sports Honda Super Cub limited in Australia. It fits buyers who want a blue-dial sports automatic with collaboration storytelling, not a plain black beater—and who prefer the 42.5 mm 5 Sports case over smaller field watches like the SNK809.
