The best-kept secret in the watchmaking industry has finally been unveiled. At Patek Philippe’s Plan-les-Ouates manufacturing facility which has been amazingly transformed for the 175th anniversary celebrations of its founding (1839 to 2014), the brand finally showcased its Grandmaster Chime Ref. 5175 – the main highlight among its commemorative anniversary timepieces.

Patek Philippe’s Grandmaster Chime Ref. 5175 is the result of seven years of research and development time. The Ref. 5175 features 20 complications including two world firsts in watchmaking: the first alarm function that strikes the time and secondly, the first date strike (activated on demand).

What’s more, the brand lays its claim to being the “only watch in the world to possess three distinct striking mechanisms: the Grande and Petite Sonnerie and minute repeater, the alarm and the date strike.”

Before attempting the challenge of identifying the 20 complications on the dial featuring the guilloched sunburst, do note that this Patek Philippe Ref. 5175 has two dials. In other words, it is a double-faced timepiece.

The other face of Patek Philippe’s Grandmaster Chime Ref. 5175 features the 24-hour display and the instantaneous perpetual calendar functions. One highlight is the four-digit year display seen in the aperture at the centre of the dial. Corrections can be made in either direction with a patented mechanism created by the brand.

A patented reversing mechanism was created to allow the case to be rotated. Once reversed, the information on the second dial feature the 24-hour indication and the instantaneous perpetual calendar indications.
