COSC
A chronometer is a high-precision watch capable of displaying the seconds and
housing a movement that has been tested over several days, in different positions
and at different temperatures, by an official neutral body, the "Contrôle Officiel
Suisse des Chronomètres" (COSC). Movements which meet precision criteria,
established under ISO 3159, are granted an official chronometer certificate.

CAREFUL USE
Maintenance : All metals may be slightly damaged by exposure to humidity,
seawater or natural perspiration. If your timepiece has been in contact with
seawater or strong natural perspiration, rinse in fresh water before drying with
a soft cloth.
Bronze : Your watch is designed in bronze, in this case a high-performance
aluminium bronze alloy, which guarantees the development of a subtle and unique
patina to match its user's habits. We recommend that you do not use abrasive or
aggressive products.
Precautions : Any component that is not properly secured or broken must be
repaired or replaced immediately. Avoid dust and shocks. Never open the watch
yourself; should there be a problem, please only take it to a CORUM authorized
dealer or authorized service center.
Leather strap : Leather straps are not suited to water activities. Water may cause
leather to crack, become brittle or change colour. Contact with perfume should be
avoided because it can tarnish or stain the finish of the leather. The endurance of
the leather strap is dependent on your care and wearing habits.
Cosmetics : We advise you to remove your watch before applying cosmetic products
such as sun creams, mosquito repellent etc.
Humid climate : Watches worn in humid climatic conditions must be checked
more frequently.
