Seiko 5 Sports x Honda Motocompo HDB010: 45th Anniversary Limited Edition
Seiko 5 Sports x Honda Motocompo: Celebrating 45 Years of the Iconic Folding Scooter
The most accessible range of the Japanese manufacturer, the Seiko 5 Sports series, is known for offering everything from classic dive-inspired models to compact field watches. Seiko also uses this platform to be creative and introduces unexpected collaborations. The latest collaboration brings a vibrant yellow dial to celebrate 45 years of the compact, lightweight Honda Motocompo motorcycle — an icon of accessible urban fun.
The Honda Motocompo: An Icon of Urban Mobility
Released by Honda in 1981, the Motocompo had a compact, lightweight body with a dry weight of 42 kg, powered by a 49 cc, 2.5 horsepower two-stroke engine. It was equipped with foldable handlebars and footrests, as well as leak-proof mechanisms for fuel, engine oil, and the battery. The idea was that it could be folded and loaded into Honda's "City" car, creating a new lifestyle combining four-wheeled comfort with two-wheeled manoeuvrability. Not a fast two-wheeler, but an unmistakable design icon.
Watch Details: Compact 36.4mm Case with Motocompo References
The Seiko 5 Sports x Honda Motocompo HDB010 is based on the compact Mid-Field Collection, with a 36.4mm diameter, 12.5mm thick, and 44.4mm lug-to-lug steel case. The matte black hard coating and black crown with "TURN" engraved on its side are inspired by the Motocompo's fuel cock design. A Hardlex crystal protects the dial, and 100m water resistance covers everyday scenarios.
The matte yellow dial carries several references to the scooter: embossed black Arabic numerals, luminous hour markers, and a transversal black bar with the Honda logo — just like the protective side bars on the motorbike. The "Automatic" logo uses the same font as the Motocompo logo. A day-date display with matching black discs adds functionality.
Motocompo-Inspired Strap Design
The black nylon strap continues the theme with loops inscribed "Carrying Point" and the strap tip marked "Insertion Point" — references to the attachment points used to secure the scooter to a car. The blackened hardware matches the case coating, completing the cohesive design language.
Movement & Technical Specifications
Inside the case is the tried-and-tested calibre 4R36, an automatic movement running at 3Hz (21,600 vph) with a 41-hour power reserve. It offers hours, minutes, seconds (with stop seconds), and day-date functionality.

Frequently Asked Questions
What makes this collaboration unique?
This is the first time Seiko has partnered with Honda for a Motocompo-themed watch. The design references are deeply integrated — from the "TURN" engraved crown referencing the fuel cock, to the nylon strap loops mimicking the scooter's car-attachment points. The special shipping-carton-inspired box completes the storytelling.
How does the 36.4mm case wear?
The compact 36.4mm case with 44.4mm lug-to-lug makes this one of the smaller Seiko 5 Sports models. It's an ideal unisex size that works well on smaller to medium wrists, and the field-watch-inspired design gives it a tool-watch aesthetic despite its compact proportions.
Is the calibre 4R36 reliable?
Yes. The calibre 4R36 is one of Seiko's most proven automatic movements, used across dozens of models for years. It offers reliable timekeeping, hacking seconds, hand-winding capability, and a 41-hour power reserve — more than adequate for daily wear.
