The Marvin watch collections comprise two distinct kinds of leather bracelets: The first, referred to as ‘Jack leather,’ originates from a first choice of plain calfskins. ‘Jack leather‘
boasts an aniline finish also known as ‘transparent,’ which reveals the natural features of the leather, and requires delicate handling. This treatment has the further advantage of reducing the risks of allergy, as the percentage of chrome present in the leather is lower than the minimum authorized by the Economic Commission for the United Nations of Europe (EEC/ UN). The result is a polished, smooth finish, particularly recognizable to the touch. The second strap is also made from calf leather and is generally used for pastel tints, which are more difficult to achieve.
Light colours are the result of a treatment based on water varnishes and natural components without the use of solvents, which gives the leather resistance to ultra-violate rays.
