Watches can be tested in a number of ways. We learned that Casio catapults G-Shocks into slabs of concrete, I saw Parmigiani use a giant hammer-like swing to fire prototypes across a room… and, most recently, Laurent Ferrier let me wear their very fine Galet Classic Tourbillon Double Spiral for a week during SIHH. I’ll say the three techniques must be pretty much equally strenuous. Here’s what wearing a truly fine piece of horology during the watch industry trade show marathon was like and how it held up.
