Wings of wartime

Pat Hughes & X4009

 

Originally conceived by Reginald Joseph Mitchell in the early 1930s, the Supermarine Spitfire has since become an iconic symbol renowned for its aerodynamic prowess, which played a pivotal role in shaping history.

Designed as a short-range, high-performance interceptor, the “Spit” swiftly assumed a vital role in confronting German fighters over the English Channel, notably during the Battle of Britain, the first major air campaign fought entirely by air forces.

Vickers Supermarine Spitfire Mk1a, bearing RAF serial X4009 and construction number 945, rolled off the assembly line at Supermarine’s Eastleigh factory in the wake of war’s outbreak. Its maiden flight occurred on July 24th, 1940, after which it was assigned to RAF Squadron No. 234 under the command of Paterson ‘Pat’ Clarence Hughes.

Hughes, now regarded as a prominent figure in the Battle of Britain, ranked sixth among the “aces of aces” during the aerial conflict of the summer of 1940, tallying at least fourteen confirmed victories.

As a flight commander, Hughes championed daring close-in tactics, securing the squadron’s initial triumphs in the fierce struggle for air superiority. Transferred to the southeast of England, he weathered the battle’s most intense period.

Flying exclusively the X4009 Spitfire, Hughes completed a total of 21 sorties from August 18th to September 7th, 1940, claiming nine victories over five separate encounters. However, tragedy struck on September 7th, 1940, when his aircraft was lost during a mission over London.

Despite Hughes’ untimely demise, his heroic exploits and the unique history of the X4009 Spitfire cement its status as one of the most celebrated and historically significant restorations of the iconic aircraft.

A piece of history

Fueselage aluminum

 

In 2020, Ross and Ann-Maree Pay of Vintage Fighter Restorations acquired ownership of the wreckage and identity of Supermarine Spitfire Mk1a X4009, excavated from its crash site in the UK, eighty years after its Battle of Britain service.

Donating the aircraft’s remains to Hunter Fighter Collection Incorporated, a registered Australian charity, they initiated its complete restoration to its original 1940 condition. Stage 1, including fuselage frame components manufacturing by Airframe Assemblies, has been completed, with Stage 2 beginning. This stage involves finalizing the fuselage structure, starting wing and tail assemblies, sourcing mechanical and electrical components, and obtaining engine and propeller cores.

While many original parts are utilized, some aluminum salvaged from the fuselage was unsuitable for restoration. These historic pieces, still bearing original marks, have been integrated into the design of the X4009 Collection at the 6 o’clock subdial.

Of the 20,000 Spitfires built from 1938 to 1948, fewer than 100 remain operational. X4009, as the only fourth flying “Mk1a” type, holds significant historical value. Proceeds from each timepiece sale contribute to the restoration, ensuring X4009’s return to the skies.

The design challenge

Spirit of the sky

 

Designing the X4009 Collection proved to be an intriguing endeavor. Leveraging our RJM series from 2018, our goal was to craft a timepiece that not only embodies the mechanical excellence of a Spitfire aircraft but also pays homage to the distinctive history of Mk1a X4009.

At the same time, we aimed to incorporate the original aluminum from its fuselage, capturing the essence of its active era.

Beginning with the case, we sought to integrate elements reminiscent of the Spitfire’s aerodynamic brilliance, particularly its wing shape and structure. The crown guard, resembling the elliptical form of the wing from above, showcases internal spars and ribs for lightweight yet robust construction. Inspired by the aircraft’s nose cone, the large onion crown adds a touch of authenticity.

On the dial side, we drew inspiration from timepieces worn by RAF pilots during WWII, offering a modern interpretation of the ‘Dirty Dozen’ watches. Featuring clear Arabic numerals, luminous hands and hour markers, and a shatterproof crystal, it pays homage to the era’s government-issued watches. Additionally, tributes to Pat Hughes and the X4009 aircraft adorn the dial.

The exhibition case-back unveils a customized Sellita caliber SW-461 movement, featuring ruthenium anthracite plating, tempered blued screws, and a rotor showcasing the X4009 aircraft in flight. Lastly, the battle-scarred aluminum takes center stage just above 6 o’clock, integrated into the small-seconds subdial, ensuring each timepiece is truly unique.
