Before production begins, a pre-series of straps undergoes a succession of tests to check their resistance and quality. Resistance to the following is tested: tension, torsion, abrasion, sweat, humidity, UV rays, water, salt water and wear.
Tension and torsion Test
The tensile resistance test is carried out by applying increasing tension to the straps until they break. The torsion test consists of subjecting the straps to torsion in order to test the consistency to flexibility ratio.
The abrasion resistance test checks the resistance of the colour of the leather to constant, continuous rubbing.
Sweat resistance test
The sweat resistance test lasts two days and is carried out by immersion of the straps in a chemical solution that replicates the characteristics of sweat at a specific pH.
This test simulates the combination of high humidity and high temperature and measures the strap's reaction to these conditions.
Uv rays test
The straps are subjected to up to 30 hours of UV rays reproduced in a laboratory simulating 6 days of sunlight in the warmest hours of a summer's day. The straps are also exposed to artificial light to simulate their display in boutique windows.
Water resistance test
This test serves to record water absorption and water resistance levels. The strap is alternately immersed in water and allowed to dry.
The pull-through test repeatedly simulates the action of putting the watch on the wrist so as to monitor the reactions of both the strap and the buckle.
