One size never truly fits all – and with this in mind, Czapek presents its Quai des Bergues model in a new, 40.5mm case. The steel case retains all of the stylistic signatures of the Quai des Bergues case – with a slight refinement of the case-side recesses in order to incorporate the movement (Calibre SXH1) – and a subtle change to the slope of the lugs to ensure a perfect fit on the wrist. To complement the new size, Czapek, together with its dial-making partner Metalem, has developed an entirely new guilloche pattern. They have named it Guilloche 'Double Soleil', after the parhelion phenomenon, an optical illusion that appears under certain atmospheric conditions as a luminous spot on one or both sides of the sun.
