Alarm Pocket Watches
Varying in appearance, alarm pocket watches tend to have a vintage, antique design. While open faced watches have an exposed dial, the full hunter watch has a hinged case to protect their inner workings. Half hunter watches have a glass insert so you can tell the time when the case is closed. Watches of this kind are exceptional time keepers, but can also be used to express one's individual style
Analogue dials
Many pocket watches have a mechanical analogue mechanism where time is represented by moving hands around a dial. As well as a minute hand and an hour hand, most alarm watches also have an alarm hand which is controlled by pusher pins located on the watch. Alarms can be activated and deactivated in various ways such as manipulating a lever.
Mechanical pocket watches
Mechanical pocket watches typically have a spring which needs to be wound on a regular basis to keep it working properly. This kind of movement is commonly seen on vintage watches, many of which make a distinctive ticking sound. Mechanical watches can be wound using a key. This is inserted into a hole somewhere on the watch and turned until the watch is properly wound.
Other setting methods include pulling out the crown and winding the stem to adjust the time. With a pin/nail set, you can also depress a button, usually with a pointed object such as a pin or nail, and then use the stem to set the time. With a lever set, you should remove the front crystal to access the time changing lever.
Quartz pocket watches
Unlike mechanical pocket watches, quartz watches do not need to be wound. Instead, they rely on the rapid vibrations of a quartz crystal, allowing for wonderfully accurate time keeping.
