We are here to help
The Mayfair collection is a series of modern, colour bursting and inspiring watches. The uniquely shaped cases are finished with exceptional attention to detail, comprising brushed surfaces and meticulously polished edges. The vibrant dials are finished with a sun-ray brushing, reflecting every ray of light, and a set of silver polished hands to match the cases.
The 40mm case combines the elegant finish of the original Mayfair with a unique, slim sitting shape and toolwatch robustness and water resistance. Underneath the scratch-resistant sapphire crystal, lume filled, silver polished hands are combined with a silver-polished, red-tipped fourth hand to track the second timezone (GMT complication). This kit is based on the NH-34A automatic watch movement, with 41 hours power reserve, 24 jewel bearings, sweeping second hand, GMT and date complication.
