Hi all,   I've recently got into watch repair, and have been following Mark's excellent YouTube videos. I had to make a repair to an ETA 2836 in my Mondaine Auto and lost the day wheel spring clip during reassembly. I hunted high and low, but to no avail. I found and bought a replacement online, but it was quite expensive.   I tried ETAs site directly, but it appears that you have to be an authorised repairer to be allowed into certain parts of the site.   Where do you recommend going for
