The outstanding originality of this watch, which is produced in a limited series of 250, lies in the hand-engraved design on the case back of Vienna’s national opera house, the «Staatsoper». Its matt white dial is protected with a sapphire crystal and adorned with small light-grey notes of music, gold Roman numerals and a permanent small seconds hand at 6 o’clock. The strap is made of crocodile leather, the buckle and case of 750 (18K) gold. This model is water-resistant to 30 m.
