Scans
Here are scans of a french Tag HEUER catalog from the very late 80’s or very early 90’s, you can use to find the reference or specification of your device. Big part of this document introduced electronic microsplit timers including the small cubic design 130 model.
About the catalog
Two exemplars are showed here (you can get one in the shop) and one still have the original jeweler sticker. They come from Switzerland. Published at the end of the 80’s (maybe early 90’s), it’s probably one of the last only dedicated to stopwatches.
