103 A Sa
Which watches aren't designated as 'classics' these days? This valued label is applied to many timepieces. Yet very few really set standards of style in functional design and first-class technology. If this term were ever applicable to a watch, then most certainly to the Sinn model 103 A Sa. The chronograph features the Valjoux 7750 mechanical movement with automatic winding. The polished stainless steel case perfectly matches the classic style of the watch.
