Hello, after many fruitless searches, I decided once again to turn to you for information on this nos lcd, I only know that it is a tissot research and that there are no photos of this on the net template. As usual, any help is welcome, thanks in advance to everyone, here are the photos:
Very cool! Never seen this «research» model before. I have this one.
The movement is very similar to the Tissot Autolub model sold in the UK around 1972.
The plastic movement parts where of a new type of material which in theory was sturdier and needed less attention.
As I remember, Tissot tried to 'innovate' new materials partly as an experiment, but the retailing only lasted a few years and they returned to more traditional materials.
Spare components are no longer available but non working examples are often purchased for donor parts.
Just throwing in this bit of info that may be of interest?
