The Windsor Wool - Herringblack strap perfectly suits my Rolex Sub. Its texture and colour perfectly complement the dial and face, whilst also being thick enough to suit the weight and width of the watch. I'd recommend this strap for anyone looking for a change from the traditional bracelet, but also wants to retain the formality of its look. Finally, I'd add that the strap is both well made and very comfortable.
Feels great, sturdy and looks amazing. After a while the wool fluffs up but can easily be cleaned up.
