Super Hamilton Estoril 300 Automatic Calendar Watch

 
Working as it should, and in lovely condition, a super Hamilton watch dating to the early 1960's. With an automatic 21 jewel movement and sweep seconds the champagne champagne dial is good, with just a couple of ageing marks, at two, and four thirty - minimal gold plating loss to the 34mmx42mm case, keeping excellent time, and with a new crystal, and leather strap.
The Hamilton Watch Company is a Swiss manufacturer of wristwatches based in Bienne, Switzerland. Founded in 1892 as an American firm, the Hamilton Watch Company ended American manufacture in 1969, shifting manufacturing operations to the Buren factory in Switzerland. Through a series of mergers and acquisitions, the Hamilton Watch Company eventually became integrated into the Swatch Group, the world's largest watch manufacturing and marketing conglomerate.
