I've purchased several straps from the wizards at Holbens over the past year. This Hirsch performance strap is a perfect fit for my SINN 104. It looks great and is super comfortable.
placed this on a oris bc3 and it not only complements but enhances the watches aesthetics and functionality
Very good quality as all Hirsch products but I think the strap was too pricey for what you get!
great band, pricey but worth it.
