Luxury watches were traditionally made in gold but with the advent of new technologies in watchmaking many new materials have come on to the market and are now widely used.The case forms the outer part of the watch, which surrounds the bezel and the underneath of the dial. This can come in materials including yellow gold, rose gold, white gold, platinum, stainless steel, titanium, ceramic and a PVD coating.
Glass is used to describe the transparent cover of the watch, which can also be referred to as crystal. Glass is used to protect the dial but can also be used on the reverse of the watch to make a transparent open caseback, which shows the inner workings of the watch mechanism.
Sapphire Crystal Glass
Sapphire crystal glass is commonly used because it is highly scratch resistant and extremely hard wearing. It is completely transparent, enabling you to see every intricate detail on the watch dial and is one of the hardest natural substances making it an excellent protector.
Mineral glass is often used as an alternative to sapphire crystal. Lower priced watches can feature mineral glass, but also some older Rolex models may also use this type of glass.
Plexiglas is the trade name for an acrylic glass, often used as a lightweight or shatter-resistant alternative to glass.
A watch clasp secures the strap or metal bracelet of a watch. There are a number of clasp options available, which are outlined below.
A deployment clasp opens out into thirds, which allows the watch to fit over the wrist and hand before it is secured into place by a small hook clasp.
Push-button Deployment Clasp
A push-button deployment clasp works in the same way but has the addition of buttons on either side of the clasp which must be pushed to release.
Fold-over Push Button
A fold-over pushbutton deployment or fold-over safety clasp has an extra security feature in the form of a fold-over latch. Along with the pushbutton, this helps ensure the clasp does not open on its own.
A hidden deployment buckle clasp is also known as a butterfly clasp. This opens at both ends of the strap and resembles a butterfly’s wings when fully opened. The clasp easily opens and closes for convenience.A buckle and pin clasp is a very common clasp closure and similar to what you can see on a belt. It features a loop and pin which are secured through holes on the strap.
A jewellery clasp is widely used on many bracelet straps. It features a latch that opens and closes when attached to the latch bar on the other end of the bracelet.
An open or transparent caseback features on the reverse of a watch and allows the wearer to see intricate details of the mechanism. It is a chance for the watch brand to show off the movement, which can often be decorated for added effect. A transparent caseback can be fully open, have a skeletonised window or cut-out shape.
The origin of a watch is where it has been assembled. Many watch brands are Swiss-made but there are a number of brands that originate from other countries, for example U-Boat is made in Italy and Bremont is made in England. Some watch brands will use Swiss-made parts, such as the movement, but the watch will be assembled elsewhere.
