Precious metals used on watch cases include varying karat golds, sterling silver and, in some very high-end watches, platinum. Crystal types also vary, but with fewer options. Generally, the crystal, which is the glass-like covering designed to protect the dial of the watch, is either plastic, mineral glass, or synthetic sapphire. Mineral glass is more common and sturdier. Sapphire crystals, more expensive than mineral glass, are not only sturdy, but also highly scratch-resistant.
Bracelets can also influence watch prices considerably.
Aside from plastic and rubber strap, leather and metal straps can dramatically affect the cost of the watch. Similarly, metal bracelets can range from inexpensive base metals to precious metals, to specially developed tungsten carbide or titanium. Today, the highly competitive market is such that the quality of watches is inexorably pushed upward, a trend which translates into a range of products constantly improved in order better to meet consumers' need and expectations. Style, design and watch brands are purely individual tastes. In any case, fine watches should be purchased at reputable jewelers or other authorized retailers who have a knowledgeable staff and strong after-sales services.
