Unconventional. Dedicated. Unapologetic.
Engineered from 316L alloy in Switzerland, this stainless steel case is expertly finished with brushed and polished surfaces. A screw-down crown ensures a water resistance of 15ATM.
Inspired by the 6b/159 aviation watches worn during the Second World War, the TRI-05’s dial features the emblem of 303 Squadron: its Kościuszko badge is embossed into a subdial at 6 o’clock.
Every detail matters. Engineered on both the top and underside, our double domed sapphire crystal offers absolute clarity of the dial from all angles. Its signature convex shape pays homage to the dress watches of the ‘40s and ‘50s – our modern take on retro design.
Visible through a sapphire crystal is a disc of P8331. Each disc is displayed as it was recovered, battle scars and all – a direct connection to Piotr Laguna and the aircraft he last flew 80 years ago. The Polish motto ‘For our freedom for yours’ is engraved onto glass, while the red and white chequerboard of the Polish Air Force is a reminder of 303 Squadron’s Polish heritage.
Emitting a luminescent green colour, the pilots of World War II would use lume to great effect during night-time operations. The TRI-05's hands are filled with Grade X1 GLC3 Super-LumiNova® - a key feature for any pilot's watch.
The SW200 features in many great Swiss-made watches – including this one. It’s a dependable automatic movement with an anti-shock system and 38-hour power reserve.
This TRIBUS arrives with a signed Certificate of Authenticity in its own luxury presentation box, piano finished with a push button for easy access. An accompanying warranty card allows you to register your watch and view your online instruction manual. We believe you don’t need to hack down half the Amazon for a physical manual when you can easily download one.
How is it that a piece of metal from a Spitfire that crash-landed in boggy French farmland in 1941 finds its way into a limited-edition watch nearly 80 years later? With the help of flight logbooks, navigation charts and pilot testimonies, historians can generally piece together a sequence of events. Yet in the case of 303 Squadron’s Spitfire P8331 RF-M ‘Sumatra’, sheer good fortune not only helped with locating the arming panel that sits in the backplate of TRI-05; it revealed a whole new dimension to its story beyond those scribblings on a page.
Spitfire P8331 RF-M ‘Sumatra’ was one of the initial ten Mk IIB aircraft delivered to No.303 Squadron at RAF Northolt on 13 May 1941. It was flown by at least 15 pilots, the majority being Poles within 303 Squadron; it is credited with taking down two Messerschmitt Bf 109s – one destroyed and one probably destroyed, plus another damaged over its 52 sorties.
Its final flight would take place on 27 June 1941, piloted by Acting Wing Commander Piotr Łaguna as part of an operation with Circus 25 (Z.181) to target a steel factory in Lille. With conditions worsening, orders were altered to “Rhubarb” – searching for enemy troops, vehicles and choice targets at ultra-low level in the Gravelines area. Having located a Luftwaffe airfield near Coquelles, just outside of Calais, the flight destroyed three enemy fighters, but German Anti-Aircraft fire came in response. P8331 was directly hit by a shell, with its flaming wreck last seen diving sharply towards the earth. Piotr Łaguna was killed whilst attempting to bail from his aircraft and subsequently buried in grave no. 9, row A, at Pihen-les-Guines Military Cemetery.
This was about as much as we knew – until the research of the Łagunas Spitfire Legacy Project revealed more of P8331’s story. They made contact with Frenchman JP Duriez, the man who helped positively identify P8331 during its excavation in June 1986. The wreckage was found lodged some 3 to 4 metres under boggy farmland. Eyewitnesses interviewed in 1986 were able to tell the tale of one German soldier who threw his cigarette into the liquid left on the surface of where the aircraft had crashed into – unaware that it wasn’t water but fuel! It set alight, singeing his and his colleagues’ eyebrows and hair, much to the amusement of the locals…
Following its excavation, P8331 would be on the move again – but at a far slower pace. Identifiable parts like its engine and propellers were moved to the Calais War Museum; its dials and cockpit instrument panel were on display in another museum south of Calais. The remaining remnants of twisted metal recovered were even stored in a farmer’s barn until the 1990s before being scrapped!
Thanks to the efforts of French regional aviation archaeologists who helped in the recovery and curation of the aircraft in 1986, Łaguna’s Spitfire Legacy Project were able to locate the majority of remaining material left of the recovered P8331, including the arming panel that features in our TRI-05 watch.
Thanks to its distinctive shape and size, and the presence of quick-release fasteners, this arming panel section was one of the most easily identifiable parts of the aircraft. Having received the panel from the Łaguna Project, we here at TRIBUS set about carefully stamping out 303 pieces of metal from the panel – each one 16.7mm across.
The release of the TRI-05 303 Squadron P8331 Limited Edition to coincide with the 80th Anniversary of the Battle of Britain couldn’t have been more perfect. A 303-piece limited edition that tells many stories within its 41mm case, it highlights the crucial role the Polish Air Force played during the Second World War. Just as significantly, its 2020 release was meant to coincide with the first time Polish veterans would partake in commemorating Victory in Europe Day after being controversially snubbed from the British Victory March of 1946 (Covid put that occasion on hold - for now).
Its backplate contains a piece of metal recovered from Spitfire P8331 RF-M ‘Sumatra’, an aircraft belonging to 303 Squadron based at RAF Northolt. Famous for downing the most enemy aircraft during the Battle of Britain, the squadron was largely comprised of Polish airmen who had previously served in the 1st Air Regiment at Warsaw. Spitfire P8331, flown by Acting Wing Commander Piotr Łaguna, would be shot down over Gravelines in France on 27th June 1941.
Surrounding the piece of precious metal, the Polish motto “Za naszą i waszą wolność - for our freedom and yours” has been engraved into glass, allowing a view of the Swiss-made Sellita SW200 movement inside. The red and white checkerboard of the Polish Air Force serves a nod to over a century of Polish aeronautical history, whilst remaining in use today.
The 303’s dial is reminiscent of the highly legible aviation watches worn by pilots during the Second World War, with green-emission lume used on its Arabic numerals and hands. The final nod to the Polish story at the heart of this watch features at 6 o’clock on the dial, where the Kościuszko badge is present. Tadeusz Kościuszko, a national hero who served in the American War of Indepence and led an 18th century uprising against the Russian Empire, would be remembered on many Polish Air Force aircraft – including the Hurricanes, Spitfires and Mustangs of 303 Squadron that would ultimately secure the victory of the Battle of Britain.
I travel an awful lot for work and always ensure that I spend time in the various airports looking at the next purchase. I find that it is difficult to find really true classic design with a clean face and uncluttered. I am a simple guy and like a watch to do what it is supposed to tell me the time. However its fair to say whilst I have truly struggled to find the right watch for a special occasion and equally one i could wear for any occasion also has been difficult.
When Tribus released this particular watch it really felt like the moment i had been waiting for, classic looks mixed with modern sympathetic features all in a Swiss made watch. But that was only the beginning! The history hidden cleverly behind the crystal panel on the back of the watch hides an 80 year old secret too, that of a Spitfire, Pilot and 18,000 Polish Air Men and Women who came to defend our shores against tyranny too. This story was and is captivating all by its self and having a piece of history on my wrist to be able to hand to my son one day makes it even more special, not just beautiful but with true heart and meaning too.
The Tribus brand have dared to be different and have firmly achieved their goal, a simply stunning watch and now just struggling to chose my next!
I am delighted with my purchase. Looking forward to the extra straps being sent on.
Very happy with purchases
This is a beautiful watch with part of a Spitfire in the back of it. You are literally wearing history as the Spitfire part was from a 303 Squadron Spitfire which faught in WWII. It is a subtly designed, beautifully engineered and a worthy addition to any watch collection.
Superbly executed design with many 6B/159 design cues. What makes this timepiece (and why this goes beyond sheer form) is the story and connection of the monumental effort and sacrifice made by all those defending The island of Last Hope during WW2. Without these valiant and fearless heroes we wouldn’t be where we are today. The Kosciusko insignia is a subtle reminder to 303 and fades into the dial in remembrance of those fallen. Equally poignant is how this is superimposed over the hour markers (losing numerical digits in the lower dial) and to me this conveys thoughts for the lost numbers of airmen and ground crew serving with the RAF at this time. Lest we Forget. It’s a truely unique piece and with a tangible connection to a Mark IIB Spitfire that fought during WW2 and defended Britain. Also supporting the fantastic cause and work of Laguna’s Spitfire Legacy (LSL). An absolute belter of a timepiece!
I’m truly impressed, this is no ordinary watch. The background story is extraordinary and to be able to hold a piece of its history, in a beautiful watch, is a gift. What has particularly impressed me, is the thought that has gone into the design, sympathetic to the watches worn by the pilots and to their bravery. The quality of build and finish is as good as any of my Omega watches. It’s a watch that I have no doubt will be passed from one generation to the next. In fact, I believe TRIBUS have gone beyond what is expected of a fine watch in delivering the TRI-05 303 Squadron P8331 Limited Edition.
