Every detail of the watch has been carefully considered, with specifications designed for both precision and durability. 🚀 A Space-Age Chronograph from Britain? Can you imagine a British-built space shuttle? In the 1960s, the UK quietly developed one — at least on paper. It was called Project MUSTARD: the Multi-Unit Space Transport and Recovery Device. A bold, modular shuttle system that could launch into orbit and land like a plane. Years ahead of its time. Never built. But never forgotten. Inspired by the future that never was .... Here at Helicon Watches, weve always been fascinated by engineering stories lost to time — and the optimism behind them. This release is inspired by one of Britains boldest what if moments — and its been a long time in the making. Its a tribute to British innovation, designed and assembled right here in the UK, and built to perform in all environments — even the most extreme.
