Patek Philippe Grandmaster Chime Celebrates their 175th Anniversary

Patek Philippe Grandmaster Chime Ref. 5175 Is Possibly the Greatest Watch in a Generation…

And, it should be. The Patek Philippe Grandmaster Chime is 175 years in the making. What makes it so special, apart from the fact that Patek Philippe is only making 7 (6 for sale and 1 for the Patek Philippe museum) and that it costs $2.5 million, that is? How about 20 complications, a stunning rose gold case and six patents. This won’t be my ordinary type of post. There is just too much to this watch for me to do it justice. So… below find the tech specs, list of patents and list complications on the Patek Philippe Grandmaster Chime Reference 5175. Oh, and definitely check out the video below. It’s a bit long, but totally worth it.
