Hi, Several years ago now I inherited a gold-cased chronograph/repeater pocket watch. I asked about it on the TZ forums and the info that was provided there was that it was probably made by Sandoz (a brand which began in the late 18th century but the watch is likely much later than that). I had put it away in the safe deposit box for a while, but my interest piqued again and so I took some more detailed photos. Any interests or observations and maybe hints about restoration would be provided. One specific question I have is about the escapement. The balance wheel has weighted screws like a free sprung balance and yet there is an index. Maybe that's just how the wheel was made? Several years ago I asked RGM about restoration and they were more than happy to take a look at the watch but sadly I never followed through. They were the best folks I could think of for something like this, I figured if there were parts that need serious work that they might be the best to manufacture new pieces. However I know nothing about the pocket watch community and perhaps there are other companies who do excellent professional restorations (maybe a bit closer to me in Boston? I actually live in 'Watch City' Waltham!)? I don't think this watch is serially manufactured (though I might be wrong) and so any documentation is probably impossible to come by. I was very close with Grandfather but had never seen the watch until after his death, so I don't think he purchased it himself. Perhaps he too inherited this piece.
Let's get onto the fun pictures.
The outer case:
The unmarked dial: I couldn't take a good picture without reflections, but you can see the 3 time hands and the jewel tipped chrono hand. The time markers are in Roman but the outer markers are in Arabic numerals.

The hammers and the 'Sine Dolo' coat of arms common to the Sandoz manufacture:
The escapement, notice the jewels below the blued mainsrping:
