I found this in an antique shop. I didn't recognise the brand, but it was Swiss, mechanical & cheap, so I bought it It's in reasonable condition although the strap is a bit tatty.
The numbers on the dial look a bit 70's to me, but any info an an approximate date would be appreciated. Also, is 421 on the back a model number or movement, again, any info appreciated. The dial is only 30mm diameter, have I bought a ladies watch?
