Having reviewed both the A. Lange & Söhne 1815 Chronograph and the Patek Philippe Chronograph 5172G manual-winding chronographs in previous days, today it’s time for a face-off between these two premium contenders. Both are undeniably beautiful examples of the ‘pure-chronograph-no-additional-complications genre’ and both are impeccably crafted. But they are as different as chalk and cheese, so please, take a ringside seat and see if you agree with our verdict in the battle of high-end chronographs pitting the Lange versus the Patek.
