The Chopard L.U.C Perpetual Calendar T

This watch from Chopard embodies Swiss watchmaking excellence through superlative functionality and a distinctive form that is timeless. This timepiece bears the coveted Poincon de Genève seal. As if this wasn’t enough to guarantee the quality of this watch, Chopard also submits the L.U.C. Perpetual Calendar T to the strict testing of the COSC, where it is officially proclaimed to be a chronometer. Chronometer certification entails that a watch has gone through 14 nights and 15 days of testing over 5 positions and it has not exceeded a variance of -4/+6 seconds daily.

The case of the L.U.C. Perpetual T from Chopard is crafted from 18kt rose gold, alternately brushed and polished. The rose gold case comes with a diameter of 43mm, currently considered to be an ideal size for most wrists. This gent’s watch carries many complications; therefore, the case rises off the wrist a relatively thick 14.9mm. Chopard outfits the L.U.C. Perpetual Calendar T with a matte black alligator leather strap. Securing the strap is a folding clasp made from 18kt rose gold. The case back is made from sapphire crystal, which allows the wearer to admire the movement. This model is water resistant to 30 meters.

The movement is a hand wound mechanical caliber L.U.C 0215-L. This manual movement features a Variner balance wheel which oscillates at a steady 28,800 alternations per hour. This watch carries two sets of double stacked barrels called the L.U.C Quattro technology, which result in a massive 216 hours of power reserve. The power reserve has an indicator that has been engraved into the movement. Decorating the movement is Cotes de Genève on the bridges, and circular graining on the main plate.

Protecting the silver dial is a sapphire crystal that has been glare proofed on both sides allowing for exceptional readability of the time under many different conditions. The dial also features guilloche worked gold and applied rose gold Roman numerals. The perpetual calendar is displayed over two subdials and a large double date aperture at the 12 position. The subdial at 9 displays both a day/night indicator and the day of the week. The subdial at 3 reveals the month, and a leap year indicator. At the 6 position is the stunning tourbillon mechanism, which rotates once every 60 seconds and is therefore integrated with the small seconds complication. Tourbillons work by creating so many variances on the escapement that they cancel each other out, and thus negate the effects of gravity.
