1. The universal watch
The perfect basic watch collection looks something like this: First of all, you need an absolutely dependable watch that prepares you for every contingency. This watch should be able to do its job in every situation, and it should be possible to repair it practically anywhere in the world. Select robust stainless steel as the material of the wristband and the case, and a tried and tested selfwinding movement from ETA or a manufacture movement with a power reserve of at least two days — or preferably three days. You can rely on water resistance to a depth of at least 100 meters if it has a screwin crown. A scratchproof sapphire crystal is standard nowadays. Make sure you get the antireflective kind, because there are big differences in this respect. The hour markers on the dial must be treated with lots of luminous mass.
