- What is the difference between a quartz movement and a self-winding movement?
The normal daily action of moving your arm is sufficient to keep a self-winding movement activated or the watch can be placed in a watch winder to maintain accurate time. A quartz movement uses a vibrating quartz crystal that powers a small motor. A mercury-free battery supplies the electric current to the crystal at a constant rate. For most watches, the battery should be replaced once a year.
- What does analog or digital mean?
Analog is a type of display that has a dial, hands, numbers or markers, subdials and sometimes a day or date window. The background can be patterned or plain to aid visibility or impart style to the design. This is the traditional watch face. A digital display usually has LED (light emitting diode) numbers and sometimes also shows a range of functions including elapsed time, date, alarms, speed, distance and even temperature. These watches are almost always battery powered, though there are also watches that use light instead of a battery.
- What is a chronograph and how does it work?
The chronograph function is for measuring elapsed time, like a stopwatch. Chronograph movements are activated with one or more buttons near the crown, and the dial usually includes one or more subdials to show the fractions of a second or elapsed minutes or hours.
- What's the difference between a watch bracelet and a watch band?
The term bracelet is generally used with a watch strap made of metal, such as stainless steel or titanium and fastens with a clasp. Many designs include links that flex easily with wrist movement, which makes them a popular choice for men's timepieces. These bracelets can be lengthened or shortened by adding or removing links.
Another metal bracelet design for women's watches uses a solid metal bangle that fastens with a jewelry clasp.
A band is often crafted of leather, patent leather or silicone rubber, and can be secured with either a buckle or a clasp. Both men's and women's watches use bands.
Both types of straps are interchangeable, some by the user, others by a watch repairman. Strap widths are measured in millimeters.
