How It All Started
The journey of Leotum began as a heartfelt tribute to Jean-Adrien's father on his 60th birthday. With a passion for watches and a desire to create something uniquely special, he set out to build a luxury clock inspired by atomic technology. Despite not having the means to buy an exquisite timepiece, he embraced the challenge of crafting one himself, embarking on a fulfilling journey that combined precision engineering with personal sentiment.
Two years of determination, research, and innovation culminated in the creation of this first atomic clock. The process involved developing a CNC machine tool, mastering its operation, meticulously designing each component of the clock and manufacturing them.
Not only had a clock been created, it was also the birth of Leotum and its idea of designing and manufacturing high-end clocks based on an atomic regulation.
With each tick, these clocks are a testament to the hard work and dedication that went into their creation, offering customers an unparalleled experience in timekeeping technology.
