The Spitfire is arguably the most iconic British fighter plane, which is why our C8 P7350 Chronometer Limited Edition – which contains a piece of Duralumin from the last remaining airworthy Spitfire that flew in the Battle of Britain (P7350) – is so special. Only 75 of these watches were made, but we we’re giving you the chance to bid for the incredibly rare ‘000’ prototype in a ‘silent’ auction.

Two charities will benefit from the auction: the Royal British Legion, and SSAFA, which we’ve chosen as a way of expressing our gratitude to our servicemen and women. The Legion offers care and advice to serving members of the Army, Navy and RAF, as well as providing support to veterans. It is the organiser of the annual Poppy Appeal. SSAFA is the UK’s oldest tri-service military charity and gives lifelong support for regulars, reservists and veterans. You can donate to both via their homepages.
