HTD

HTD is the watchmaking microbrand born in Florence from the meeting of Federico Del Guerra and Federico Zulian, two enthusiasts of mechanics and horology who came together during their university years. The project officially took shape in 2020 with its first chronograph collections, Hesagraph and Jungle, the result of a genuine passion for precision and craftsmanship.

Behind the name HTD — Horological Tools Department — lies a clear idea: watches are not merely timekeepers, but tools. Tools that evoke the bold spirit of the last century — made of motor racing, exploration and high society — where what truly matters is action and speed, whether on wheels, under sail or by propeller. A vision shaped in part by figures such as Renzo, a watchmaker devoted to micrometric precision, and Piero, a mechanic convinced that every engine has a soul.

Every HTD collection is produced in finite numbers: once a batch is complete, the brand moves on to a new project, always designed from scratch. It is a commitment to exclusivity that makes each watch a unique, unrepeatable chapter — created for those seeking a timepiece that tells a special story and is built to last, far from passing trends.

At Calibro, you'll find the available selection of HTD watches: chronographs and wrist tools for enthusiasts who value character, craftsmanship and a design that moves through the eras rather than chasing them.
