Vintage Marcasite Cocktail Rotary Watch & Box Silver Importers SD

Was given to me as a gift many years ago (was second hand then from an antique shop).

I can see 4 stones missing but only using a magnifying glass. Nice silver security chain too.

The watch & strap is marked silver and is working. Beautiful piece but time it is worn again.  Too small for me to read the time when I wear it now 😞

Weights 20g.  Total length is 17 cm. Face is 2 x 1.5 cm.

Beautiful black winder.

Lovely box "Watches of Switzerland. New Bond Street - London & Provinces.
