Nicknamed the “Bumblebee” for its striking black dial and bold yellow inner bezel, this Seiko 5 Sports has quietly become a cult classic among collectors. It’s powered by the reliable 7S36 automatic movement with 23 jewels and boasts a 100m water resistance rating — specs that make it a solid everyday tool watch. But what sets this reference apart is its distinct look and uncommon build: a dual-crown setup with an internal rotating compass bezel, something rarely seen in the Seiko 5 line.

This particular piece was made in Japan, and features a brushed stainless steel case, Hardlex crystal, and a 3-link bracelet. The display caseback gives a full view of the movement inside — a detail that wasn’t standard on all Seiko 5s from the era.

Though never officially named by Seiko, the “Bumblebee” moniker has stuck in enthusiast circles, thanks to its unmistakable color scheme and offbeat design. Discontinued years ago and increasingly hard to find, especially in original condition, it’s a sleeper hit in the world of vintage Seiko — quietly gaining value and recognition among fans of the brand.
