GUSTAVE et cie watches are guaranteed for 2 years.
The warranty only applies when a part is defective or a manufacturing defect is found. It cannot take effect if, during disassembly, the watch shows obvious traces of fall or impact, immersion, or sand, in the event of misuse or manipulation of internal mechanisms, chemical corrosion, or due to batteries. Bands are not covered by the warranty.
In the event of a problem, send your watch directly to us by registered mail, accompanied by the warranty card supplied with your watch and duly completed with the reason and return address. It is advisable to ship it without the band.
