PH Zhou is a student at the Massachusetts Institute of Technology, where he studies economics and computer science. He is a devoted enthusiast of vintage watches – in particular early- to mid-20th-century chronographs.


When we talk about vintage chronograph movements, there are many deserving of our attention – from the relatively common Valjoux 72 that powers anything from a Rolex Daytona to a Gallet Multichron 12, to the exceedingly rare and complicated Caliber 13-130 that resides in a Patek 1518 Perpetual Calendar Chronograph. However, as much as it is a sin to claim this for the latter, neither of the two movements we just mentioned are truly "in-house," since the Caliber 13-130 is still ultimately based on a Valjoux ebauche. In fact, the number of companies that produced both watches and movements were few and far between.

With the lilt of Irish laughter

Every day and in every way

Now forever and ever after."
