We have introduced the outer watch part basics before,now we explain each part in detail.
The case holds the inner working parts of the watch. Depending on the style of the watch, the case is usually made of stainless steel, because steel is resilient, handles light shocks that the watch could receive, and doesn’t tarnish. Cases can also be made of precious metals like gold or platinum, and can even be made of plastic in sports watches. The case can also come in different ﬁnishes like high-polish, smooth, matte, or a combination of any of those. The case also contains the movement itself, be it electronic (quartz) or automatic (self-winding). We’ll cover more on movements later.
The lugs are where the case of the watch connects to the strap or metal bracelet of the watch, by use of metal spring bars.
The crown is used to change the time. Some watches offer a date window and a seconds indicator, which are engaged by pulling the crown out. Crowns on water-resistant watches screw down into the case. The crown can have embellishments like precious stones, to indicate luxury and attention to detail.
Strap / Buckle
The strap/buckle secures the watch to your wrist and there are a number of materials commonly used for these parts. Leather straps range from calfskin to lizard and more exotic offerings like ostrich, alligator, crocodile, and even toad. Instead of a strap, a metal bracelet is a popular option. Other options are nylon straps (for sportiness), satin straps (for dressiness), and rubber straps (for diving/watersports). Most watches allow straps and bracelets to be interchangeable so you can dress it up or down when you want to change the look of your watch.
The hands, usually broken down into hours and minutes, indicate the time. The hour hand is usually shorter in size than the minute hand. The hands can also have a slight design to them.
Other more complicated watches, such as chronographs (stop watches / timers), may have additional hands for their other functions, known as “complications”.
The bezel is the outer ring of the case that connects to the lugs. It is typically a ﬂat-edged surface, but can also be rounded. The bezel can also have embellishments, like precious gemstones in upscale watches, and may be a different metal than the case itself, as in some two-tone watches.
The above pictures show three different kinds of watch bezels. The one on the left rotates, allowing to use as a stopwatch.While the other two are fixed, just a decoration.
Dial / Face
The dial is where the watch can be the most expressive. It is the ﬂat surface beneath the crystal, and can come in many color options, textures, and materials. Dials can use Roman numerals, Arabic numbers, or even more simple stick bar markers to indicate the time.
