At the end of last year, we were able to get our hands on the Breguet Classique Complications 1907 pocket watch worth one million U.S. dollars. This massive 18K yellow gold pocket watch regulator weighing almost three quarters of a pound —338.2 grams to be precise— and with a case diameter of 56.50 mm, is no joke. This is by far, one of the heaviest pocket watches we have ever reviewed and one that is definitely worth its price.
