I recently bought Tissot seastar on ebay. The watch is in excellent condition - very little wear considering the age of the watch. I now want to find out when it was produced - and other useful information about it, which caliber it uses and so on. I can not open the caseback because I do not have the necessary tools available

After countless hours on google im still struggling with Identifying it, and hope someone has enough knowledge to help me.

The images are very large in size so I uploaded them on Imgur. Click this link for pictures.

All help is greatly appreciated!

Hello,

Production date will be between 1969 & 1974.
If you have to push the crown to change the date it's a 2571 movement in other case it's a 794.
