I ordered the FKM black rubber Tropic strap to pair with my Steeldive 50 Fathoms Homage. The strap is out standing quality both in terms of look, fit and feel. It's the period correct and perfect partner to the watch. The strap was also delivered very quickly. Will definitely buy from North Straps again.
There's a reason I keep coming back for North Straps. I have several of their natos and this is my second rubber strap, and my first 'tropic'. It's lovely and pliant. No need to wear it in, or soak in hot water to get it to shape. Soft, and not at all sticky. Just the ticket.
