Warranties & Repairs

At Twain Time, trust is our timepiece's best friend. Our commitment to quality spans every pre-owned watch and mechanical marvel in our collection. Should the unexpected occur, count on us to swiftly make things right. We treasure our clients' satisfaction and trust above all else—this ethos echoes through every member of our team.

Each pre-owned watch undergoes meticulous, non-invasive mechanical scrutiny and servicing if needed. This ensures they not only meet but exceed our stringent standards for accuracy and functionality.

Rest easy knowing that unless otherwise noted, our pre-owned watches come with a robust warranty—either full or limited—spanning twelve months. However, this doesn't cover damages from misuse or accidents. Given their age, some watches may require gentler treatment than when they were brand new.

For those watches serviced by their original manufacturers, they bear the manufacturer's guarantee, surpassing our standard warranty.
