AD ASTRA, the Latin expression for "to the stars", is an invitation to embark on an intergalactic journey. A purple titanium spaceship and a blue planet come to life in offering a unique experience. The former, with its 13.59mm diameter, is embodied by an oversized tourbillon at 12 o'clock. The latter, represented by a blue sapphire, boasts an exceptional 3.92mm diameter (featuring 16 sides and 208 facets) and gravitates opposite the tourbillon, thus providing pleasing visual counterbalance. These two elements are suspended above a 1.8mm opaque black titanium dial.
