. EXCLUSIVE AT MR PORTER. Bamford London’s ‘Mayfair Sport’ watch is modelled after the replacement style the brand would send to customers while their timepiece was being serviced, it proved to be such a hit that the label issued a selection of colours. Designed to stand up to daily wear, this yellow one has a yellow polymer case and rubber strap built around a steel core. It’s powered by a Swiss-made Miyota 2035 quartz movement, encased in sapphire glass and features Super-LumiNova®-filled hands for legibility in low-light conditions.
