Da marca:
Produced to demanding specifications, this watch is ideal for adventurous types. It has undergone rigourous testing in the Brand’s own watchmaking laboratory to guarantee its accuracy, durability and water-resistance.
Some of these tests take place inside a climate chamber, where the watch’s resistance is assessed under extreme climatic conditions. Watches are exposed for several days to temperatures varying from -50° to +200°, at humidity levels from 0% to 100%, in order to replicate climatic conditions on the different continents.
These conditions allow the case’s corrosion resistance, the behaviour and alteration of the oils and lubricants used and the durability of the soldering to be tested.
Exposure to UV radiation allows the reaction of the sapphire gaskets, hands, dial and strap to be tested in order to detect any alterations or discolouration.
To test their resistance to impact, watches and movements undergo the demanding 5000G test, among others. This machine simulates extreme conditions using a hammer, which strikes the watch attached to a support.
The straps also undergo numerous tests, including the “Straptest” which measures the resistance of the leather or fabric to torsion and tension. For a fabric strap, the machine applies 3000 pulls and 3000 twists under both damp and dry conditions.
Finally, to test the requirement for water-resistance down to 100 metres, each Highlands case is immersed in a tank of demineralised water and subjected to a pressure of 10 bar.
It then undergoes the condensation test to confirm its water-resistance.
