Empty Weight

The box is in my eyes a good compromise between level of protection and weight. I love to travel light. I will always prefer Nylon or plastic over heavy luggage. My vertebras and disks have to serve me for another couple of decades and if you travel a lot, you will travel with less and less stuff. That does not necessarily mean less watches. But when I remember how much stuff I carried around when traveling and teaching for an American Computer company, then my back starts hurting just from the memories...
