A thick strap that's built to endure, the Heavy Calf has a Rembordé Look Coupé Franc treatment, with three-layer edge lacquering and a uniformly-coloured outer surface. The lacquer treatment imbues the strap with both scratch and water resistance, while the stark white contrast stitching completes its sporty appearance.

Strap would get 5 stars but I ordered the Sport folding clasp with it and no matter which way round the clasp, there is just too much metal backing and it rubs and digs in. Had to remove it in the end as it is just too unpleasant to use, shame as otherwise the quality is high as usual with Hirsch. The strap is great quality and you can feel the difference between this and cheaper straps the thickness is perfect on a Navitimer. Having quick release spring bars, fitting another strap colour so easily is a great idea. So far so good on wear and tear still looking as good as new.

Superb fit and finish on my vintage Breitling Navitimer 1806 Looks like The original Breitling strap. Nice with quickrelease springbars.
