The shape and sizing of the case respond to precise robustness, aesthetics and portability. It is made from a single metal block, for coining and removal. The remarkable thickness has allowed the shock resistance and other stresses needed to meet the harsh military needs. The screwed back helps ensure waterproofness up to a depth of 100 meters, both for the classic model and for the chronograph. It is further strengthened by the collection of gold coin 18 Kt with the brand of Atelier. The case is made in 18 Kt gold, in bronze or in steel.
The bezel is engraved and enamelled by hand. A small coin, specially coined with the Atelier brand, refers to the meridian time. It is one of the elements that characterise the collection. The internal springs system and the steel or carbon rack allow for a convenient and precise rotation, reliable solution that expands the clock's use.
The screw crown is well protected by the uprights of the case. The form and the dimension have been studied to hold it easily. In the screwed position, the crown makes the case perfectly water, humidity and dust proof. It makes that side of the watch very resistant thanks to a small gasket steel tube which guarantees resistant use with time. The same technique has been used for the push buttons on the chronograph.
