La F. stands for “La François” and is named after one of Édouard’s closest childhood friends. It’s a mid-size watch by today’s standards as the case comes in with a diameter of 40mm, a lug-to-lug of 45mm, a thickness of 10.20mm (including the crystal) and a lug width of 20mm. As its dimensions indicate, it sits flat on the wrist and is extremely comfortable to wear. And one might think that with only 10.20mm of thickness and an early bird price tag of $341, one would find a quartz movement within. But one would be wrong.
