The first CLUSE collections had cases produced in brass. In 2016, we launched our first collection with stainless steel cases. After being able to compare feedback on both materials for some time, in 2018, we started to transition all our watch and jewellery collections to stainless steel. In the watch industry, stainless steel is considered qualitatively superior, more durable and a more sustainable material in comparison to brass. Moreover, it allows for more recycling options.
