I've read that people enjoy being able to change out their straps often by themselves but I haven't been able to find instructions on how to actually do this (carefully). The SA helping me said I would need a tool and that she didn't know where I could get one. Why H wouldn't sell this is beyond me. I'm not sure if the design of the watch has changed in recent years, but if it matters, my watch has a P stamp (2012). Can anyone please help?
