Day/Date Watch |
A watch that indicates not only the date but also the day of the week. |
Deployment Buckle (Fold over) |
A three-folding enclosure that secures the two ends of the bracelet and allows enough room for placing the watch on the wrist when fully deployed. When closed, the buckle covers the two-piece folding mechanism. |
Depth Alarm |
An alarm on a diver's watch that sounds when the wearer exceeds a preset depth. In most watches it stops sounding when the diver ascends above that depth. |
Depth Sensor/Depth Meter |
A device on a diver's watch that determines the wearer's depth by measuring water pressure. It shows the depth either by analog hands and a scale on the watch dial or through a digital display. |
Dial |
The dial, often referred to as the face is usually marked with numbers or batons to which the hands point in order for the wearer to tell the correct time. Dials may be minimalist with no markers at all or extremely complex as in the case of pilots' chronographs. Dials may be decorated with patterns or in some cases with precious stones. |
Digital |
The display of time in numbers instead of hands on the dial. The numbers can appear in an LCD (Liquid Crystal Display), which shows a continuous reading or an LED (Light-Emitting Diode), which shows the time at the push of a button. |
Display |
Indication of time or other data, either by means of hands moving over a dial (analog display) or by means of numerals appearing in one or more windows (digital or numerical display); these numerals may be completed by alphabetical indications (alphanumerical display) or by signs of any other kind. Example: 12.05 MO 12.3 = 12 hours, 5 minutes, Monday 12th March. Such displays can be obtained by mechanical or electronic means. |
Diver's Watch |
Divers watches traditionally feature a graduated, rotating bezel, screw down winding crown, and case back... must be water resistant to at least 200m or 660 feet. |
Dual Time |
A watch that measures current local time as well as at least one other time zone. The additional time element may come from a twin dial, extra hand, sub dial, or other means. |
Dual Time/Second Time Zone Bezel |
A rotating bezel, which can be used to display a separate time zone distinct from that shown on the dial. |
