Mark is a great teacher and this course is very thorough and enjoyable, but explained in a very straightforward and practical way. Stripping and reassembling a movement is very satisfying. After taking this course I was able to get a cool old Croton watch from the 1950s running again – which was an incredibly rewarding experience. I just enrolled in level three and can’t wait to take the next steps. I would recommend this course as a must for anyone interested in watchmaking.
