956 Classic

This model is no longer available in our current range.
956 Classic

Precise, indestructible mechanics integrated in a timeless, aesthetic design – a common denominator that unites aficionados of classic cars with connoisseurs of fine watches. Our 956 series is a highly functional, durable chronograph with a look that accurately recalls the style of the traditional dashboards in classic cars.

All of the features of this watch series – from the functional details to the appearance – were designed with automotive concepts in mind. As in the world of automobiles, the Sinn 956 shows how long it can keep running: the additional integrated complication for the power reserve indicator is designed to look like a fuel gauge, of course. The double tachymeter scale around the dial includes both the range from 30 to 60 km / h which is so important for the classic car rallies, as well as the high-speed range from 60 to 500 km / h. For all its technological sophistication, the Sinn 956 Classic also offers the reliable durability of traditional mechanical workmanship: it is shock-resistant and anti-magnetic, well-protected against all the rigors of demanding use under tough conditions by a solid stainless steel case and scratch-resistance sapphire crystal glass. Thus, even a drive in a roadster through a violent thunderstorm won't faze a SINN 956 Classic.
