It looks like we're starting school back in September and I will likely have to interact with about 1500 fourteen to sixteen year-olds on a daily basis again in an area where things are hardly under control. For a watch, I'm assuming that I should be wearing something all metal, including a bracelet so it can be cleaned regularly (thus excluding all of my favorite vintage watches...). I have a Seiko 5 that fits the bill, but it's only 30m water resistant - will it be able to cope with soap and spraying sink water? Would a 100m watch or 200m diver be needed?
