To mark the 50th anniversary of Les Ambassadeurs, Ulysse Nardin has created a special version of its Sonata Streamline. Only eight pieces are available for this chronograph, which is engraved on the caseback with the limited edition number along with the Les Ambassadeurs logo. Providing useful information for travellers - from the innovative alarm/alarm to the indication of a second time zone - it is equipped with an in-house movement, the self-winding UN67 calibre, with a 22-carat gold rotor and silicon escapement. The dial, in black with red gold details, is framed by a ceramic bezel in the same shade, as is the alligator leather strap. The titanium case, with a diameter of 44 millimetres, is guaranteed water-resistant to a pressure of 50 atmospheres.
