MORTIMA Super De Luxe French-made Manual Wind Watch

This is a manual wind wristwatch, Super De Luxe, from the French watch manufacturer MORTIMA.

I purchased it used about 30 years ago, used it a few times, and then stored it.
For this listing, I removed the strap and cleaned it.
The main body is very clean, with no visible scratches or rust.
The buckle is also very clean.
The leather strap may not be the original, and it shows some signs of wear. The thin leather on the underside has peeled off, but it is not visible when worn, so I don't think it affects the appearance.
I also tested its operation, and it seems to gain about 40 seconds per day.
