Maystone is an independent British watch brand founded in 2023 by Gregory Mayo. Based in the United Kingdom, the company was established by Mayo following his extensive experience in the horological industry, including roles in graphic design and brand management for other established British watch labels. This background in 3D design and creative direction heavily informs the brand’s aesthetic and technical approach.
The brand’s identity is defined by a design philosophy inspired by the natural world, specifically birds of prey. This thematic influence is integrated into the structural elements of the timepieces, such as the sharp, twisted lugs designed to mimic wingspans and handsets and indices that reference the shape of talons. Enthusiasts are often drawn to Maystone for this original design language, which avoids the common tropes of “homage” watches, as well as for the brand’s focus on providing high-specification mechanical movements at an accessible price point.
The cornerstone of the Maystone catalog is the Prosperity GMT, which serves as the brand’s flagship model. Launched via a successful Kickstarter campaign in 2024, the Prosperity GMT features a 38mm stainless steel case, a Seiko NH34 automatic movement, and a water resistance rating of 10 ATM. The collection has since expanded to include several thematic variations that utilize distinct color palettes and finishes, such as the Golden Eagle with its 18K gold-plated accents, the Snowy Owl featuring cooler tones, and the Red Kite model. Each piece typically incorporates a signature “M” shaped seconds hand counterbalance and a custom-engraved caseback.
