Restoring a Heuer Chronograph - Every Detail Matters

This time on the bench we are restoring this vintage Heuer chronograph from ca 1945. The watch is not running and there is an issue with the hairspring. The watch belongs to my brother and I'll do my best to restore it to original condition. In this video I'll show the process of disassembly, adjusting the hairspring back into working condition, assembly and oilding of the movement as well as a complete case restoration. The importance of every small detail is apparent throughout this restoration as there are troubles with chronograph functions and brokwn jewels.
