About Chronoglide
Chronoglide was founded by Kalle Slaap (1972), a passionate independent watchmaker with many years of experience restoring exclusive timepieces. What began as a small workshop has grown into a place where craftsmanship, precision, and a passion for technology converge.
Besides restoration, Kalle believes in the power of knowledge sharing. With his book “Watchmaking Explained,” and a critically acclaimed YouTube channel, he helps a new generation of enthusiasts and professionals discover the craft for themselves.
