Before production begins, strap samples undergo a series of tests to check their resistance and quality. Resistance to the following is tested: tension, torsion, abrasion, sweat, humidity, UV rays, water resistance, saltwater and wear
The abrasion-resistance test checks the resistance of the colour of the leather to constant, continuous rubbing, at various levels of intensity.
The straps are immersed in a liquid having the same composition as seawater. One day of testing corresponds to around 3 weeks of immersion in seawater so as to test the resistance, brilliance and non-deformability of the strap as well as the buckle's resistance to corrosion.
