Nice watch. I really like that whole line. Winding - I think you'll find that the power reserve will keep it going through the night. If not, it shouldn't hurt to give the stem a few turns to get it moving, then a few more to keep it going. Then, strap it on and go about your business. I have a number of auto winders and I'm bound to a desk virtually all day. Even my sedentary habits will keep them wound. And you shouldn't have any trouble with over winding - automatic movements have clutches that prevent damage from over winding. Not sure about the Hamiltons, but a glance at the manual should cleat that up. Sent from my SM-N910V using Tapatalk[/quote] Yeah I haven't had any problems with it at all. It runs a little on the fast side but it's still less than a minute fast after 2 months of wearing it (meaning it still reads exactly to the minute with my GWS, it's just 30ish seconds fast). It has been an awesome watch so far. I replaced the band with a Maratac Mil Series Nato and I forget I'm wearing it, it's a good bit lighter than my GWS even being a 42mm vs the GWS's 40. I guess that's where the titanium vs stainless comes into play. Probably most impressive to me is how the sapphire has resisted scratching (hopefully I don't jinx myself here) but I expected that since it has a slightly domed surface that it would scratch, but after 2 months of wear I have some light wear marks in the black coating but nothing on the sapphire. It seems like a really tough watch so far.
