DISTINCTIVE DESIGN
SOARING INFLUENCE
The Prosperity GMT is inspired by birds of prey. Each model reflects their character, bringing those qualities into a watch that is practical, bold, and unmistakably Maystone.

SHARP TWISTED LUGS
The graceful curves of this case are reminiscent of birds of prey’s wings in motion. With an interplay of textures – the brushed sides and polished top create a striking contrast.

MAYSTONE SECONDS
The distinctive seconds hand is in the shape of an "M," symbolising Maystone. This sets it apart from conventional watch counterbalances.
After-Hours Clarity
Super-LumiNova ready



QUICK-RELEASE SOLID END LINKS
Change the strap on your Maystone Prosperity GMT with ease using the convenient Quick Release function.

ON-THE-FLY MICRO ADJUSTMENT
Wear your Maystone watch in comfort, with three sizes you can adjust without the use of any tools, right in the clasp.
