Chronograph: Functioning similarly to a stopwatch, a chronograph is a unique and valued complication due to its ability to measure increments of elapsed time while the watch still maintains traditional timekeeping abilities. The crown controls the analog watch while function pushers allow you to start, stop and reset the chronograph subdials. Variations of chronographs include the double chronograph with two separate stopwatch mechanisms and the flyback chronograph which allows the user to stop, reset and start the chronograph with a single depression of the function pusher.

Quartz: Although not as mechanically complex as other engines, the quartz movement provides the most accurate and reliable time-keeping. This type of movement typically draws power from a battery and centers around a small vibrating chip of quartz crystal. When an electrical current, supplied from a battery, is applied to a quartz crystal, the current is distorted and creates a precise resonating frequency. Watchmakers employ the subsequent frequency to measure time. Some adaptations to the traditional quartz movement include introducing rotors and power cells in an effort to maintain the accuracy of quartz while eliminating the need for a battery. Quartz movements have been used in timepieces since the 1970s and are highly accurate, dependable and affordable.

The case provides the foundation for all other major watch components. It houses the movement, maintains the lugs for attachment to the bracelet or strap, plays host to various crowns and function pushers, and seats the crystal and bezel.

Cases exist in a variety of shapes and sizes and utilize a library of materials for construction such as stainless steel, gold, ceramic, titanium, plastic, and more. The dominance of stainless steel in case construction remains, however, hypo-allergenic metals and materials, like titanium, continue to gain in popularity. Metal cases often have particular finishes - such as a smooth reflective polish or circular matte brush - that enhance the presentation of the timepiece and give it unique depth.

Some designs allow for the case and lugs to be curved in order for the watch to have a more comfortable fit around the wrist. The back of a case will typically be removable and most likely be screw down or pop-off. It is important to note, however, it should only be opened by a trained professional. An exhibition feature (found within a case's back) refers to an added window that allows you to view the movement and is often found on automatic and mechanical timepieces.

Case Size:
Case measurements do not include crown or lugs.

  • Round - One measurement, 8:00 to 2:00
  • Square - One measurement, 3:00 to 9:00 or 6:00 to 12:00 (should be the same)
  • Rectangle, Tonneau, Oval, Octagon, etc. - Two measurements, 3:00 to 9:00 and 6:00 to 12:00
  • Watch Case Dimension Comparisons:
    It can be difficult to determine how a watch will fit on your wrist without trying it on first. Get a better feel for the size of a watch case by comparing the case diameter to the following diameters of common objects:
  • Nickel: 21.21mm
  • Quarter: 24.26mm
  • Half Dollar: 30.61mm
  • Poker Chip (standard): 39mm
  • Ping Pong Ball: 40mm
  • Golf Ball: 42.67mm
  • Tow Ball Hitch (ISO standard): 50mm
  • Racquetball: 57mm
