This is a slab of 1970's Kitch, Kienzle released the Boutique range in 1971 its was meant to be Space Age and colourful and it succeeded. 
These watches will be very collectible in time, they are already selling for way past their original new price !  This particular bangle is great for two reasons it's in very good condition and it comes in its original Boutique tin with even the orange cloth inside. 
 
The watch itself is silver plated with a steel back, the case, dial and bangle being in very good condition. Inside the case is a Kienzle German made Movement 
 
Overall cosmetically this is in very good condition
