Bracelet/Strap

leather watch strap

Leather Fabric Worn daily, a leather watch strap will be affected by the pH of the wearer's skin and other external factors:

Water and damp rapidly deteriorate leather
Light causes fading
Dust leaves a film of dirt

For these reasons, a watch should be kept in its box when not worn.
A leather strap will normally need replacing every 1 to 3 years, according to use.

Steel Titanium/Tantalum
Resilient steel bracelets are intended for intensive and/or sports wear. The most likely signs of wear are to the bracelet's appearance, as steel is easily scratched while knocks may cause dents. Link attachments can work themselves loose over time. The links, which give the bracelet its supple feel on the wrist, are held in place by screws or spring bars that will gather dust.

Yellow gold/ Pink gold/ White gold/ Platinum
A gold or platinum bracelet is prone to scratching and dents that alter its appearance. A white gold bracelet will have a tendency to yellow, depending on the amount of palladium in the alloy and/or the quality of the rhodium plating. The links, which give the bracelet its supple feel on the wrist, are held in place by screws or spring bars which, because they move with the bracelet, are subject to wear. Depending on conditions of use, dust can build up that will abrade or obstruct the links.

Rubber/Acrylic
These supple straps are less prone to scratching and dents but can tear or alter with use.
