Sinn Watch 836 Vintage Cowhide Brown. 836.010 Sinn watches are constantly impressing us with their sporty and sophisticated designs that are not only handsome but contain some of the greatest innovations in the watch industry. This Sinn 836 watch is the perfect instrument for a professional man in need of a reliable and attractive timepiece boasting a stunning 43mm polished stainless steel case that has been hardened using Sinn’s famous TEGIMENT technology. This impressive innovation makes the metal extremely scratch resistant while also improving its Magnetic Field Protection up to 80,000 A/m. Hidden within the stainless steel case of this Sinn 836 watch is the ETA 2892-A2 self winding movement, a Swiss made calibre which equips the timepiece with classic hour, minute and seconds function, a date window at 6 o clock and a power reserve of 42 hours. The striking matte black dial becomes the centrepiece of this Sinn watch thanks to the bold red seconds hand and the beautifully crafted hour and minute hands coated in luminescent colour that allow easy legibility in the dark. To complete the look of this Sinn 836 watch, a vintage brown calfskin leather strap is added alongside a stainless steel buckle.
