Sandy Gunn and Spitfire AA810
Flight Lieutenant Alastair ‘Sandy’ Gunn was a courageous pilot in the RAF’s Photographic Reconnaissance Unit (PRU), an elite group tasked with flying unarmed Spitfires deep into enemy territory to gather critical intelligence. On 5th March 1942, during a high-risk mission to photograph the German battleship Tirpitz in Norway, Gunn’s Spitfire AA810 was intercepted and shot down by two Messerschmitt Bf 109s. Though he initially evaded capture, he was eventually caught and interned in the infamous Stalag Luft III prison camp.
Determined to resist even in captivity, Gunn became part of the daring mass breakout later immortalized in The Great Escape. In March 1944, alongside 75 other POWs, he crawled through the painstakingly dug tunnel Harry into the freezing night, risking everything for a chance at freedom. But reality was far harsher than the Hollywood version of events. The escape was gruelling, fraught with tension, and ultimately, most of the men were recaptured. In an act of brutal retribution, Hitler personally ordered the execution of 50 of the escapees—Sandy Gunn among them.
His life was cut short, but his extraordinary bravery and the sacrifices of the PRU pilots stand as a testament to their unwavering courage and determination. They flew alone, unarmed, and deep behind enemy lines, knowing the risks yet never hesitating. Gunn’s story is one of resilience, sacrifice, and an unbreakable spirit—one that deserves to be remembered.
Today, the restoration of Spitfire AA810, led by Tony Hoskins, aims to honour the bravery of PRU pilots like Gunn. Discovered in Norway’s Surnadal hills, the aircraft is being returned to its former glory, with Zero West sponsoring the cockpit instrumentation. This project not only revives a piece of history but also commemorates the courage of those who flew unarmed into enemy territory. Gunn’s story, from his daring missions to his role in the Great Escape, remains a powerful reminder of the sacrifices made during the war.

RECASTING HISTORY FOR THE S6e
Zero West Watches has crafted a truly unique tribute to aviation history by incorporating original aluminium alloy salvaged from the legendary Spitfire AA810 into its latest timepiece edition. AA810, a PRU (Photo Reconnaissance Unit) Spitfire, carried out critical intelligence missions during World War II before being lost for decades and later recovered. To honour its legacy, 100 serial number plates were meticulously cast from this rare material for the S6e, each forming a distinctive part of the watch’s design. These plates serve as a direct connection to the aircraft, preserving its story in a tangible and enduring way.

Melting the alloy in a furnace
The investment casting process behind these plates was a masterclass in precision and heritage craftsmanship. The original master part was designed and 3D printed in-house before being used to create wax replicas for lost wax casting—one of the oldest and most refined metalworking techniques. One of Britain’s last remaining lost wax investment casters then hand-cast each plate by melting the historic alloy and vacuum-casting it into moulds, ensuring high-integrity, homogenous castings. Once cast, the plates were carefully de-sprued, hand-finished, and laser-engraved before being fitted to the watches. Each piece is completely unique, carrying the spirit of AA810 and cementing its legacy in a timepiece built to last for generations.
