A NEW EMOTION
To evoke a new emotion while adhering to a rigorous set of standards established over half a century ago is a delicate task.
Yet this is precisely the ambition of the ref. 5303: to embody the spirit and legacy of ocean exploration through a professional-grade instrument equally suited to celebrating life’s defining moments on land.
FIGHTING MAGNETISM
Preventing magnetic fields from affecting the accuracy of a mechanical watch can be done in two broad ways: making a silicon hairspring or building a soft iron cage around the movement.
We chose the traditional method by building a cage made up of three parts to redirect the magnetic fields.
This construction now improves the magnetic resistance of the 5303 reference by more than 10 times the Swiss standard, going from 4800 A/m to more than 50000 A/m.
