Super quick delivery and a lovely strap. Very impressed with the service provided and would definitely recommend. Many thanks ?


Fast delivery. Exceeded expectations. Very comfortable


PRACTICAL - The Robbie looks at home in a suit or swim shorts, the best compromise between an elegant strap and a practical waterproof strap. Great quality and great service thank you!


THE BEST OF BOTH WORLDS - The Robby is an exemplary modern strap that fuses the pliability and sporty comfort of rubber with the classic good looks of leather. The colored stitching looks especially excellent when matched with the right watch dial, bringing out subtleties or just the right amount of 'pop' without going too overboard. This strap has done time on my Tudor, Breitling, and Ball watches – both in and out of the water, and seems every bit on par with the OEM straps that those brands could produce. I own two Hirsch straps in the Performance series and am about to add a third – they're just that good.
