Welcome to ChronoHackers

ChronoHackers is a showcase for interesting do-it-yourself watch projects from across the web. It works the way Hackaday does for electronics: someone, somewhere, builds something remarkable at their bench, and we find it, write it up, and send you to the source. One subject — watches — covered with genuine curiosity about how people make them.

It is not a shop and it is not a review site. There is nothing here to buy. Every post points outward to a real maker doing real work, with a short write-up to explain what they made and why it caught our eye.

Why This Exists

Most of the watch world online splits into two camps: places that sell you watches, and places that review the ones you can buy. Very little celebrates the people building them from scratch — the ones machining a movement, etching a custom PCB, or coaxing a sixty-year-old calibre back to life on a kitchen table. That work is scattered across Reddit threads, YouTube channels, GitHub repos, and maker forums, and it rarely finds a wider audience.

ChronoHackers exists to gather it in one place and give it the attention it deserves. It is for the making, not the buying.

What You Will Find Here

Projects span the full range of horological tinkering.

Mechanical builds. Movements assembled from kits or cut from raw stock, escapements, hand-finished bridges, and the occasional ambitious complication attempted in a home workshop.

Electronic and smartwatch builds. ESP32 and nRF wearables, e-ink and round-LCD faces, custom carrier boards, and open-source watch firmware.

3D-printed watches. Printable cases, dials, and components, and the small but growing scene of designers making wearable timepieces you can run off a printer at home.

Restorations and repairs. Dead movements brought back to life, full teardowns, and the diagnostic detective work that goes with them.

Tools of the trade. Winders, timing machines, jigs, and the homemade kit that makes everything else possible.

If it involves a watch and someone built, hacked, modified, or revived it, it belongs here. Polished product launches and unboxings do not.

How It Works

Every feature starts with a real project by a real maker. We discover them across the usual corners of the web, then write a short, original piece that explains what the project is and why it is worth a look. The aim is to give you enough to understand the idea and decide whether to dig in yourself.

Attribution is the rule, not a courtesy. We credit the maker by name and link straight to their original post, video, or repository every time. ChronoHackers is a signpost to good work, never a substitute for it. The goal is to send makers more readers, not to keep those readers to ourselves.

Who It Is For

People who own both a loupe and a soldering iron. Watch enthusiasts curious about what is possible beyond the catalogue, makers who have wandered into horology from electronics or 3D printing, and anyone who enjoys watching a clever build come together. No particular expertise is assumed, only an interest in how things are made and a willingness to be impressed by other people’s ingenuity.

ChronoHackers is a love letter to the people building watches in sheds, spare rooms, and workshops — written for the people who want to join them. We find the projects, tell you why they matter, and hand you the link. The rest is up to you.
