I'll be heading out of town in about a month or so for some much needed beach time. Recently I've been wearing my PAM111v3N on rep rubber strap and was hoping to take it with me but I'm afraid of wearing it around water. I have yet to get my watch waterproofed but I've been quite afraid of doing it as it doesn't seem as it would have good resistance to water....especially with it not having a screw down crown. My question is is it worth having my 111 waterproofed or should I use this as an excuse to buy an AP Diver v5? I appreciate any advice on the matter.
