This category is named after a special material. The OLIVVIA® leather has been developed by our mother company, Weinheimer Leder GmbH. Here, an extract from olive leaves is used for the tanning process. The resulting leather is absolutely sustainable and extremely allergy-friendly. Therefore, this leather has passed all the tests and requirements by the Swiss watch-strap industry. Weinheimer Leder GmbH is the only company worldwide to use this tanning process on calf leathers. Our products are therefore absolutely unique!
