The pain
Feared by hobbyists, dreaded by professionals…
This is where theory and practical execution come together. Don't know what you are doing? You will mess it up. One wrong move, and your balance spring is ruined, leaving you in frustration.
But it doesn't have to be this way.

Your teacher
Learn from master watchmaker Kalle Slaap
Kalle Slaap is the founder of the Chronoglide Watchmaking Academy, a Fellow of the British Horological Institute, and the author of Watchmaking Explained. Through his workshop and his channel he has built a global community of more than 60,000 members who learn the craft the way it is actually practised at the bench.
“I finally understood what I was looking at through the loupe. Kalle explains the spring like nobody else.”
“'Watchmaking Explained' changed how I work. Seeing the same clarity up close is worth clearing the evening for.”
“I used to avoid balance jobs entirely. Now they are the part of the service I look forward to.”
Last call
Only so many seats at the bench
Seats are limited, and the Q&A at the end is only open to registered attendees. Bring your hardest balance and spring question, and Kalle will answer it.
