Did you get to the end of Cole’s engrossing Datograph In-Depth and feel like you need even more incredibly high-end chronograph content? If so, hit the link below for a Three-On-Three that offers an exhaustive and comparative look at Patek Philippe 5170G, the Vacheron Constantin Harmony Chronograph, and the A.
