I got this in part of a trade and am having trouble finding much information about it.
I know the movement is rare but most of the information I could find relates to high end watches that used this movement.The condition isn't great, but it runs and the chronograph functions work. The main second hand does occasionally stop/stutter which seems to be because the teeth of the two gears ocassionally missing contact. I would like to have it repaired or restored but, to be honest, it doesn't have sentimental value to me so I wouldnt want to put more into it then I could get out of it. I took it to two local watchmakers but one basically told me "Tissot's are junk so its probably worth about $50" and the other said he doesnt repair vintage watches. I don't expect to get an accurate valuation online but I just want to know if it's worth the $600-$1,200 it would take to restore. Any help would be appreciated.
