Selling three 20mm straps. The two Havestons are new and never worn, I wore the white strap for a few weeks. The white rubber strap is O2 brand and is their vulcanized rubber model that is softer and doesn’t have stuff stick to it like some other rubber straps. It has a little micro tear on the shorter strap, it’s hard to see but I tried my best to capture it. It is designed to be integrated with the 40mm subC, not sure what else it fits. Asking $70 shipped for all three in the US. $40 shipped if you just want the the two Haveston and $40 for the rubber.
