View on Hemel Watches’s site ↗Reference HF Series The Sky Racer chronograph watch was designed to re-case the highly respected ST19 column-wheel mechanical chronograph movement, previously featured in our Air Support pilot watch series. The result is a bold cushion-case chronograph that balances purposeful design with refined execution. A clean, functional panda dial is elevated by an unexpected sandpaper-textured finish, complemented by thoughtfully appointed details throughout the case and dial. Inspired by classic aviation chronographs, the Sky Racer blends mechanical heritage, tool-watch functionality, and modern design innovation into a distinctive microbrand chronograph. • Movement: Seagull ST19.
