Maybe I'm "Retro", or maybe I'm actually a Luddite, but I find that I absolutely love these hand wind pocket watches that simply, but beautifully, just tell time. No bells, whistles, alarms, or "Apps" of any kind. The first one I ordered did not work upon arrival but, while I was waiting for Shoppe Watch to replace it (which they did in short order), I also bought this one. They are lovely, seem to keep good time, and I get a real sense of satisfaction every time I pull one of them out to check the time. I seem to do that far more often than would actually be necessary, but hey... The instructions suggest winding them once a day, at the same time (so as to establish a habit?) "20 to 40 turns". I'm concerned that that may result in over-winding and damage the watch. Instead, each morning I select the "watch of the day", set it, wind it a maximum of 20 times, then give it a couple of turns each time (or every other time) I check the time. Seems to work well. They're always still going strong at bedtime. The only problem I see with these is that they've become addictive: I've now got a different one for each day of the week and am trying to resist getting more. But they are sooo cool!
