There are some watches that are considered, more or less, must-haves, and for various reasons – if not must-haves, then at least watches you should experience on some level if you’re interested in watches at all. Some members of this group are fairly self-evident: the Rolex Submariner, the Omega Speedmaster, any simple Patek Philippe, the Lange Datograph, and so on. Obviously, the basis of such a list is not ownership per se, but rather, the accumulation of the direct, personal experiences so essential to a contextually grounded enjoyment of watches and watchmaking (personally, I’d put the JLC Atmos in there as well, to say nothing of the Reverso).
