The limited run of box sets each comprises a pair of watches inspired by the two iconic aircraft that defended the nation, the Spitfire and the Hurricane. Paying homage to Bremonts first historic limited edition, the EP120, the dial design of the chronograph is inspired by the Smiths clocks that can be found in the Spitfires that flew during the Battle of Britain. The Bremont BOB Spitfire has a closed case back featuring a beautifully stamped top profile of the aircraft from which it draws inspiration, namely the Supermarine Spitfire, the most widely produced and strategically important British single-seat fighter of World War II.

The Spitfire is renowned for winning victory laurels in the Battle of Britain along with the Hawker Hurricane, the aircraft which inspires the 40mm Bremont BOB Hurricane. This model takes design cues from the clocks seen in the iconic Hurricane and turning this piece over reveals its closed case back featuring a stamped profile of the British single-seat fighter aircraft.
