I recently picked up a thrashed and battered Tissot Aquasport based on a picture of only the outside. When it arrived and I opened it up, I found that someone had scavenged the parts for the sweep second function.
The pinion was damaged when they removed the driving wheel.
I tried in vain to find spare parts, but this seems like an obscure caliber for Tissot. Anyhow, I serviced it and cased it up. The movement runs well and keeps good time.
The dial and hands look great, in my opinion.
I like how it cleaned up, but I do wish I could find parts to replace the second hand.
Anyone happen to have a parts movement for a Tissot 17.5 handy?
