OUR TAKE
A hand-winding column wheel chronograph from a British microbrand, with a dial that looks 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, double-domed sapphire, and each one QC'd and regulated by Horologium in the UK before it ships. 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. Gen2, full kit, plus an Archer rubber strap thrown in.
