Handle it gently and with care; avoid mechanical shocks (stones can easily break).
When not wearing it, keep it in a soft fabric pouch.
Avoid contact with any type of water (showers, swimming pools, sea, rivers) as certain components will oxidize more quickly this way.
Do not wear it in your sleep, while you are training or at the beach.
Avoid contact with creams, perfumes, oils, or other chemical products.
