Apple Watch Leather Strap Casablanca Ultra real Titanium

For our Casablanca Modern watch strap, we use vegetable-tanned cowhide from Tuscany, just like the Hunter. By avoiding chemical treatment, the leather retains its natural character.

Leather that is tanned with vegetable agents is called vegetable leather. It is also referred to as vegetable-tanned leather, tan-tanned leather or old-tanned leather. Vegetable tanning was the predominant tanning method for several centuries. Today, only less than 10% of all leather is preserved using vegetable tanning.

Oak and spruce bark, tara pods, olive leaves, quebracho wood or mimosa bark are used to tan the leather. The active substances found in these plant species are called “tannins”. They are produced and stored by the plants to ward off predators. Up to 300 plant species worldwide are capable of producing these active ingredients. At Fluco, our vegetable-tanned straps are tanned with “Quebracho” tannin from Argentina.

Tanning with vegetable agents is generally considered to be more expensive than the related chrome tanning. The main reason for this is that it takes up to 30 kg of bark or 20 kg of fruit to tan a single hide. The properties of the finished natural leather are determined by the acidity of the broth used to tan them. With acidic tanning broths and a sufficiently long tanning time, a relatively firm leather product can be achieved. Softer leather, on the other hand, is obtained with sweet broths.

Our Casablanca is made from a firmer leather. This in turn makes it more difficult to process the leather, but this is no problem for the experienced and skilled hands of Fluco employees.

The decisive difference to our Hunter strap, however, is that the Casablanca is a double-layered leather watch strap. On the upper side is the vegetable-tanned cowhide and on the underside our well-known beige-colored allergy-protected lining leather from a well-known German tannery.

Furthermore, the Casablanca has a slight crowning, which gives the upper leather a completely different feel.
