Questions from the description
Movement: Seiko NH35 24-jewel automatic
Hand-winding, hacking seconds <-- what does this line mean? hacking seconds vs. sweeping second hand? how can it be automatic AND hand-winding?
dealaholicAutomatic means that it doesn't require a battery. All automatics can be hand wound as well as wound by the counter weight within the watch. Hacking seconds doesn't refer to the second hand moving around the face. It means that when you pull the crown out the second hand stops moving. This is useful if you want to sync watches/clocks.
dealaholicThe NH35 is a mechanical automatic moment (winds itself from your moving your wrist around) that you can also hand wind if you need to "jump start" it if you haven't worn it in a while. Like all mechanical watches, the hand sweeps. Hacking means that the second hand stops moving when you pull out the crown to set the time. This allows you to "hack" the watch on the 0 second, set the time to upcoming minute, wait for the new minute to arrive on your time reference, and then push the crown in at the 0 second of the new minute, effectively allowing you to set the watch down to the second of accuracy. It also allows for a group of watches to be hacked to the same second so everyone does something at exactly the same time. This is the old "synchronize our watches" trope from movies and TV.
FameusNot all autos can be hand-wound. It's a very useful feature, especially if you work a desk job where your watch is unlikely to get a full wind from arm movement.
JoeDwarfOh my mistake. Every automatic watch I've had has the ability to be hand wound and most reviews I've seen on automatics also can be hand wound. I assumed they were all able to.
