AS 1977-2 INT


This shaped movement was put into many ladies' watches of the seventies. It appeared in different version on the market.

This movement only displays hour and minute. That’s a tribute to its small size.

This movement also carries the suffix “INT”, which stands for the combination of Durowe, SEFEA and Ebauches S.A..

The AS marking is pretty wrong here, since that movement differs a lot to the AS 1977.
