- Passion for watches: Philipp grew up in a small village near Lörrach, close to the Swiss border. His passion was sparked at the age of 15, when he visited a watchmaker's workshop and saw delicate gears come to life. Ever since, he has been fascinated by the technical perfection and craftsmanship behind every fine watch. For Philipp, watches are a window into the world of engineering.
- Why HORANDO? “I love sharing this enthusiasm with an international audience and bringing the finer points of luxury watches closer to our readers.”
