This Limited Edition Sinn 103.172 has not only the lovely green metallic look dail, it also features a Concepto C99001 automatic-winding chronograph movement. This movement is by Concepto, a relatively young movement manufacturer, having been founded in 2006 by Valérien Jaquet. They specialise in the creation of exclusive calibers that are entirely produced and assembled by the Independent manufacturer. This Concepto C99001 is an anti-magnetic as per DIN 8309 movement features 25 jewels and beats at the frequency of 4Hz (28,000 vph).

The case is 41mm of diameter — with 47mm lug to lug spacing — and 16mm thick polished stainless steel case with a band lug width of 20mm and a screw-fastened case-back along with a screw-down crown and crown guards. The 200m water-resistant (and pressure resistant) case meets the technical requirements for waterproofness, as set out in standard DIN 8310. It’s a decently weighted watch coming in at 77 gramme weight sans strap. 

This Sinn is a limited edition release of 500-pieces only. It comes in mint condition as a full set with an additional Sinn steel Bracelet. More than a full set and a collectors item!
