Constantin Bujor


Repairing various makes and models of watches, working with both mechanical and quartz movements.

Over his 56 years of experience, Constantin has come across many brands and models of watches. Although pieces have the same principles, all designs are different and therefor vary in the work needed to repair them.


Being a one-of-a-kind watchmaker is never boring, with no one piece being the same as the last. While he studied for a long period of time, Constantin says most of the knowledge he gained from his extensive time in the trade.
