Wristshot, 13th December: A fresh wristshot of what I consider to be my signature watch, the Girard-Perregaux WW.TC Tribute to John Harrison. Why signature? There are a few reasons. First it is a very special and rare watch and secondly, I had to go through a significant effort to get it. The special dial makes this very recognisable and for that it is an easy pick for my signature watch. One of the greatest GPs from all time.
