Early pocket watches
The watch was first created in the 16th century, initially in spherical (Pomander) or cylindrical cases, when the spring driven clock was invented. These watches were at first quite big and boxy and were worn around the neck. It was not for another century that it became common to wear a watch in a pocket.
There are two main styles of pocket watch, the hunter-case pocket watch, and the open-face pocket watch.
Open-face watches
An open-face pocket watch is one with the winding-stem at the top of the dial, above the '12' and with the seconds sub-dial at the 6 o'clock position. As the name suggests, these watches have cases which are without a cover to protect the watch-crystal from damage. All railroad chronometers had to be of the open-face kind.
Hunter-case watches
A hunter-case pocket watch is the kind with a spring-hinged circular metal lid or cover, that closes over the watch-dial and crystal, protecting them from dust, scratches and other damage or debris. The majority of antique and vintage hunter-case watches have the lid-hinges at the 9 o'clock position and the stem, crown and bow of the watch at the 3 o'clock position. Modern hunter-case pocket watches usually have the hinges for the lid at the 6 o'clock position and the stem, crown and bow at the 12 o'clock position, as with open-face watches. In both styles of watch-cases, the sub-seconds dial was always at the 6 o'clock position. A hunter-case pocket watch with a spring-ring chain is pictured at the top of this page.
