The size of an average men’s wristwatch today lies anywhere from 39 to 41mm. Watches below 39mm are considered boy-sized while those above 42mm are generally regarded as upsized. One of the greatest myths in the luxury watch industry is that people with slim wrists cannot wear large watches because it’s not about the size of the case, rather, its specific design and what kind of lugs it has.
Irrespective of size and shape, watches with a curved profile hug the wrist gently so they’re very comfortable to wear. They are, however, more complex to produce but some manufactures insist on it. Lug design may also affect the wearability of an upsized watch. Integrated lugs provide the watch with a seamless aesthetic, as if the strap or bracelet and the case are one.
In the case of the Franck Muller Vanguard, for instance, the integrated strap follows the curves of the case to wrap itself comfortably around the wrist. As much as they are bold and audacious, some watches are upsized for a very good reason. Often, the more complicated a movement is, the more components it has, so the case has to be large enough in order to fit everything in. Being the Master of Complications, Franck Muller has many watches that are upsized, most ostensibly, the grande complications in the Aeternitas and Revolution collections.
