Bamford Watch Mayfair Sport Black MS-BLK. Whilst fashionable in design, the Mayfair Sport is water-resistant to 10ATM, making it ideal for outdoor sports. It comes on a rubber strap with a unique wickerway function and the LumiNova indices mean you can see the timepiece at any time of the day. Built around a steel core, the high impact polymer case and bezel come in a number of different colour options with a brand new dial and dial configuration, providing wearers with the opportunity to express their personal style and taste.
