Caliber

A caliber can be described as the type of movement used in a watch. It is expensive and impractical to design a unique movement for each watch model, so most manufacturers often use the same movement in different watch models, sometimes with significantly different designs. The term "caliber" is due to the fact that initially the type of movement was designated by a number (in inch lines) corresponding to its largest size; however, today unique names or alphanumeric indices that are not directly related to sizes are widely used.

Knowing the name of the caliber on which the watch you are interested in is built, you can, if desired, find more detailed information about the mechanism and determine how its characteristics meet your requirements.

Strap colour

The main colour of the watch strap/bracelet.

The most popular shades nowadays are stainless steel(the colour of most metal bracelets, not necessarily steel ones), golden(bracelets made of gold and "gold"), black(strap made of different materials, including rubber and nylon, as well as separate bracelets) and brown(mostly leather straps). Other colour options include beige, white, yellow, green, camouflage ( military style), red, orange, pink, silver, grey, blue, and purple.

In addition, some models of watches are equipped with two-tone straps. Most often, white, gold and black are used as secondary colours, and this colour is specified after the main one — for example, “blue with white” or “stainless steel with gold”. If this paragraph lists several colours separated by commas — for example, "black, red, blue" — this means...that the watch is either sold in several versions that differ in the colour of the strap, or comes with several interchangeable straps / bracelets of the corresponding colours at once. This nuance should be clarified separately.
