The Sinn 103 A Sa HD is an extremely rare special edition, limited to only 300 pieces worldwide. This model from March 20, 2006 combines classic instrument watch design with robust technology and high collector’s appeal. Inside is the reliable Valjoux 7760 hand-wound movement, renowned for its precision and longevity. The coveted panda dial with black inlay gives the chronograph a striking, sporty and elegant look.

A special technical feature of this special edition is the Sinn AR dry-keeping technology: the case is filled with argon inert gas and fitted with a drying capsule that permanently binds residual moisture. In combination with special EDR seals, the ingress of moisture is greatly reduced. This technology ensures significantly better long-term stability of the movement, prevents glass fogging under extreme conditions and increases overall functional reliability – a feature that is otherwise more familiar from professional watches.

The watch comes as an absolute full set: original purchase invoice, warranty card, complete box with outer box, booklet including envelope and a new, handmade Juchten Racing leather strap from the Rios 1931 manufactory. The watch comes from first hand, has only been worn very rarely and is in correspondingly excellent condition. An exceptional opportunity for collectors and lovers of the Sinn 103 series.
