With its distinctive round form and hunter case back, featuring the rare elegance of a completely invisible hinge, the DB29 evokes the timeless allure of 18th-century pocket watches. It masterfully blends a deep reverence for traditional watchmaking with the cutting-edge complexity of De Bethune’s most advanced movements, including the mesmerizing tourbillon and the groundbreaking Maxichrono. A true celebration of heritage and innovation, this timepiece is a testament to De Bethune’s relentless pursuit of horological excellence.
