. EXCLUSIVE AT MR PORTER. Bamford London’s ‘Mayfair’ style was originally the brand’s loan model – Mr George Bamford decided to launch it permanently after receiving so much positive feedback from customers. Built with a blue polymer case and matching rubber strap with a steel core, this ‘Sport’ version has a Swiss-made Miyota 2035 quartz movement and sapphire glass case. It comes in red and yellow, too.
