This is a very rare Tissot "SYTAL", meaning SYnthetic Tissot Auto Lubrication. The plastic movement is also known as "Astrolon" It was developed by Tissot in the late 60s and was only sold in small numbers in the early 70s on the Italian market. The development of the inexpensive Quartz watch put to death the space in the market for this product.In 1975 almost the entire stock of 500.000 pieces of these watches were incinerated in Italy, therefore making this watch a very rare collectors piece.
You can read the entire history of this watch in the book I have illustrated, "Tissot 150 Years of History"
It comes in a luxury Red presentation Box. Which is a remanufactured product.
There is no paperwork or guarantee.
