Bio—Henry Hatem

The fascination with all things mechanical started in manufacturing at an early age. I became proficient in precision prototyping and production from micro to large components. The fields ranged from medical to watchmaking with everything in between.

I studied for two years at the WOSTEP certified Watch Technology Institute (WTI) in Seattle, WA where I obtained my certificate in watchmaking. While in school I also obtained AWI certifications for Watchmaker, Electronic Watch Technician and Clockmaker.

I spent the next few years as an independent watchmaker before I took a position as Instructor of watchmaking at WTI in 2001. 3 years teaching included further training at WOSTEP in Neuchatel Switzerland, Lititz Watch Technicum, Beverly Hills and other various courses and training.

Challenge called once again and I was asked to work for the prestigious Roger Dubuis in North America. Here I was privy to the world of high grade perpetual calendars, chronographs and complications.

This experience is put into every service we provide.
