I distorted a scrap hair spring just to see if I could put it right . You guessed it I’m still trying to put it right. Dexterity is everything!

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

Excellent work Mark, and thank you for the opportunity of viewing it. Keep safe, work more on watches and keep us busy watching your videos these days!

Best vid on Hairsprings to date! I can’t wait to see what happens to that bent staff pivot. Have one of those on the bench now.

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.

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.
