Brilliant Bullhead. I service and restore Seiko and Citizen watches as well and love working on the 8110a movements. They are challenging to get right especially the chronograph bridge. Loved that you made a stake on your lath to tighten the bearing race on the winding weight. Well done.
Thanks! The 8110a has such an interesting design, right? I agree the chronograph bridge can be tricky. The levers that are mounted on the underside of the bridge should be positioned so that they don't engage with the cams on the chronograph wheels. Another complication with placing this bridge is that the escape wheel jewel sits in this plate too, that pivot is so easy to break off.
Thanks for the feedback! I will look into improving the music/sound in future videos. May I suggest you could turn the volume down or off on the video for this one :)
