Patek Philippe Grandmaster Chime Ref. 6300G-010, New White Gold Version with Blue Opaline Dials

Flagship of the commemorative pieces presented on the occasion of the manufacture’s 175th anniversary in 2014, the Patek Philippe Grandmaster Chime entered the regular collection in 2016 endowed with a white-gold case and black and white dials. Its timeless style now extends to a new white-gold version with two elegant blue opaline dials.

The first Patek Philippe wristwatch with grande and petite sonnerie, this double-face reversible model also stands out as the most complicated Patek Philippe wristwatch in regular production.

Its 20 complications include five chiming modes, including two patented world firsts: an acoustic alarm that strikes the preselected time and a date repeater sounding the date on demand.

The case, adorned with a hand-guilloched hobnail pattern, is notable for its patented reversing mechanism enabling the watch to be worn with either dial on view.

The front side, with its center decorated with a hand-guilloched hobnail motif, displays the on/off indications for the acoustic functions, together with civil time, a second time zone, the moon phases, the date, and the power-reserve indicators for the movement and the strikework.

The reverse side is devoted to the perpetual calendar, with a central four-digit year display surrounded by four subsidiary dials (analog date, leap-year cycle, day, month and 24-hour indicator).

Between the two 18K gold dials beats the caliber 300 GS AL 36-750 QIS FUS IRM manually wound movement comprising 1,366 parts.

The drive energy is stored in two double barrels, one for the movement, the other for the strikework. Isolator mechanisms make the watch easy to use and exclude all risk of damage from accidental mishandling.

The new Ref. 6300G-010 with blue dials replaces the previous version in white gold with black and white dials.

It is accompanied by white gold cuff links with blue opaline centers, decorated with a hand-guilloched hobnail pattern.
