Our Epsom French Calf is an embossed grain, chrome-tanned leather from the Tannery Haas and Tannery Du Puy, near the river Rhine and in the alpine regions of France. Epsom calf leather is a classic, with excellent resistance against scratches and water. It is used for many leather products by high-end brands such as Hermes and it is incredibly water and scratch-resistant and easy to clean. Epsom's grain is more pronounced due to it being embossed, making it great for dressing down your watch for a casual appearance.
