Ulysse Nardin has unveiled a new timekeeping masterpiece - The Imperial St. Petersburg. The timepiece, to join the Ulysse Nardin Marine Collection, will be available in a limited edition of 30 platinum pieces.

The Imperial St. Petersburg watch reveals a hand-crafted oven-cured enamel dial. The dial of the watch is crowned with an applied gold double-headed Eagle, the emblem of St. Petersburg.

True watch connoisseurs will admire the majestic movement - UN-26, with a 22-K gold rotor, through the transparent case back. The precision of the movement is guaranteed by the C.O.S.C chronometer certification.

The movement provides the iconic oversized small seconds counter and a large date display at 6 o¡¯clock. It gives an advantage of a 42-hour power reserve.

The refined case of the Imperial St. Petersburg measures 43mm in diameter, incorporating a screw-crown and sapphire crystals. Each piece is individually numbered. The timepiece boasts 100-meter water-resistance.

The Ulysse Nardin Imperial St. Petersburg is housed in a unique multi-layer white translucent enamel Egg of the Tsars.

The outstanding creation is adorned with 4.25 carats of diamonds, recreating iconic symbols of St. Petersburg, including the Arch of the General Staff Building, the Rostral Columns, the Admiralty Spire, and the legendary drawbridges opening at night for large vessels to pass.

The egg is linked to the white marble base with help of Ulysse Nardin¡¯s anchor.

The Ulysse Nardin Imperial St. Petersburg watch and the Egg of the Tsars are sure to enjoy great success among collectors.
