OUR TAKE
A hand-winding column wheel chronograph from a British microbrand, with a dial designed to look like a watermelon. Pink dégradé centre, green tachymeter ring, black seed-shaped hour markers. It shouldn't work, but it does. Underneath the colour is a proper watch: Seagull ST-1901 movement with blued screws and Côtes de Genève finishing on full display through the exhibition caseback, and a double-domed sapphire up front. At 38.5mm with a 44.5mm lug-to-lug it'll sit right on basically any wrist. This is the kind of independent watch that actually does something different instead of just talking about it. Gen 1 — the original 2021 run, before the brand blew up. Full kit.
