In part 2 of this series we are fixing several faults with our Seiko Automatic Chronograph with the 6139B movement. This is an early access video for Patrons to enjoy but an edit will be made available on YouTube when the project is completed.

  1. Dear All,
    I have just completed the Mark Lovick Fault Finding Course and I would definately recommend all of his Watch Repair Courses to anyone that is interested in mechanical watches and wishes to increase their knowledge and understanding.
    Mark is an excellent teacher of this subject and he makes his courses interesting and enjoyable to do, many thanks to Mark!

  2. Amazing Mark. The way you manipulate the hair spring is truly incredible. I am still learning the skills as an amateur and I learn something every time I view your videos. Many thanks. I can’t wait for the next one. Cheers regards Steve

  3. There is nowhere else on the internet where you can find this kind of detailed instruction on the subject of watches. Not to mention such a combination of technical skill, videography and gifted teaching ability. I have many times counted myself fortunate having found such a resource in Mark Lovick. Live long and prosper, my friend.

  4. Masterful work truing that balance wheel. Why us a balance screw holder on the stud screw? Seem fraught with danger of snapping the screw in half, at least in my hands.
