This model in particular pays tribute to the Spitfire that brand Co-Founders Nick and Giles Englishs father operated and is now owned by Rolls-Royce. The PR Mk XIX was the last of the specialised photo reconnaissance variants of the Spitfire, one of the few with a Griffon engine and arguably the finest of them all. The ALT1-C Griffon remains true to each of the technical principles behind any revered automatic timepiece. Integrating an impeccably modified, chronometer-rated Valjoux 7750-SO BI AC movement, the ALT1-C Griffon brings together the art of watchmaking with the very best of technical innovation, precision and durability.
