Vintage watches are collected for their craftsmanship and character but the skills and craftsmanship required to hand-make watches are still available today despite most watches being made on a production line. This doesn't mean, however, that modern mechanical watches are any less valuable and despite usually requiring winding up, they keep very accurate time.
Wind up: There is something classic and enjoyable about interacting with a well made watch and a more traditional watch wearer might enjoy the contact that comes with winding up their watch. However, you do have to remember to wind your watch up and even when doing so they can gain or lose up to 10 seconds per day. Hand-wound watches store energy in reserve so you can take it off but typically not for more than a day or two
Automatic: An automatic watch is a mechanical watch that typically has a balance wheel escapement which automatically winds the watch in response to the movement of the wearers arm. In other words, the wearer's movement winds the watch up. Automatic watches can be stored on a winder to rotate the watch when it's not being worn. They may gain or lose a few minutes per month
As with the mechanical watches, electronic movement comes in a variety of forms.
Quartz and electronic watches: Electronic watches basically have no moving parts. They are driven by an electric charge (from the battery) which makes a small piece of quartz vibrate at a set frequency to regulate the time. Most modern electronic movements use something called a piezolectronic effect on a tiny quartz crystal to make it vibrate, which in turn drives the mechanism and allows the watch to keep extremely consistent time, typically only gaining or losing 10 seconds per month. The principle is significantly less complicated and therefore cheaper to manufacture than mechanical or automatic movements.
Branded Quartz Watches
Seiko Kinetic: Seiko use an innovative movement that responds to the wearer's wrist motion, storing energy and maintaining quartz accuracy. A power reserve indicator shows exactly how much energy you've created.
Citizen Eco-Drive: Light powered, developed by Citizen, the Eco-Drive system converts natural and artificial light into energy to give quartz accuracy. Stores power for up to 5 years.
