Your AQUASTAR watch or instrument is guaranteed against all manufacture defaults for a period of  18 months . This guarantee does not cover the defects which could arise from damages caused by the user himself. The change of the battery, which life can last 24 months depending on its use, is not covered by the guarantee. 

Your advantages  :

All parts such as the crown, the case and the pushers are in stainless steel. Your watch or instrument has been created to resist utilization in intensive sport activities.

You are in direct contact with the manufacturer. This is one more guarantee that your watch or instrument will be serviced at any time by those who have manufactured it.
