م4
The M4 is designed for those with a deep appreciation for retro aesthetics, packed with bold design tension and mechanical allure.
The M4 captivates at first glance with its sculpted case, echoing the sleek, sensual curves of 1960s vintage race cars. However, the true magic lies beneath the hood. The re-engineered case structure mimics the technical construction of an automobile engine cover—when the wearer lifts the "hood" to reveal the engine block, it creates a tactile and intimate mechanical experience.
Powered by a Japanese Miyota movement, the M4 embodies the reliability and durability synonymous with Japanese automotive engineering. Its dial draws inspiration from classic speedometers, channeling the raw energy of vintage dashboards into a wrist-worn masterpiece.
