This is an outstanding course on watch repair. I develop online educational courses for a living and this is one of the best courses I’ve seen. Mark’s explanations are very clear and the video shots of tools and watch parts are of extremely high quality. I have finished Level 1 and when I took the assessment at the end I expected it to be simple because many online courses that offer additional courses make the first ones easy to pass so you can move on and pay for the next one. However the assessment for Level 1 was challenging and truly tested my knowledge of the material. That actually makes the course even more valuable in my eyes. I’m very excited to move on to Level 2!
