From Architecture to Horology: The Story of Michiel Holthinrichs
Michiel Holthinrichs, a 36-year-old Dutch architect turned watchmaker, has redefined high-end horology by blending 3D printing with traditional craftsmanship. His brand, Holthinrichs, operates from a restored 17th-century arsenal in Delft, a city steeped in history and innovation. According to Holthinrichs’ official website, the brand’s 2025 expansion into a 755m² space marks a pivotal shift in its mission to build a local watchmaking ecosystem.
The Explosive Legacy of Delft
Delft’s history is marked by explosions—both literal and metaphorical. In 1654, 30 tonnes of gunpowder detonated in the city, a disaster that now contrasts with its modern reputation as a hub for innovation.
Artists like Johannes Vermeer and thinkers like Hugo Grotius once called Delft home, embedding the city with a cultural legacy that Holthinrichs now channels into his designs. His first model, the Ornament 1, features a case inspired by the city’s historic fortifications, a nod to Delft’s enduring impact on art and engineering.

Challenges and Breakthroughs
In 2012, Holthinrichs faced skepticism. “Many doubted 3D printing could work for horology,” he recalls. His first prototypes, produced in collaboration with a Belgian studio, were met with curiosity. By 2016, the Ornament 1 launched, with only 7 pieces made. “I sold my vintage watch collection to fund it,” he says.

The process is meticulous.
The Delft Legacy and Future Ambitions
Holthinrichs’ atelier, housed in a 1602 arsenal, is a testament to his vision.
Building a Dutch Horology Ecosystem
Despite its success, Holthinrichs faces challenges. The Netherlands lacks a traditional watchmaking infrastructure, forcing him to source components globally. “We partner with a Rotterdam-based workshop for complex machining,” he notes. His goal? To create a local ecosystem. “If we can support young watchmakers, it benefits the entire industry.”
