Buying a pre-owned watch
- Box and papers: the original box, warranty card and bill add value and help prove the watch is genuine.
- Serial and model numbers should match the papers.
- Movement: a quartz watch should keep accurate time; an automatic watch should start when worn or wound. Ask when it was last serviced.
- Authenticity: for expensive watches, check engravings, weight and finishing, and consider getting it checked at an authorised service centre before paying.
Buying gold and silver jewellery
- Markings: look for hallmark and purity markings on the piece, and ask for the original bill and any certificates. A trusted jeweller can test the purity before you pay.
- Price by weight and purity: check the day’s gold rate. Making charges from the original purchase are not recovered when reselling.
- Get it tested at a jeweller before paying for high-value pieces.
- Silver is usually hallmarked with its purity, such as 925 for sterling silver.
Gemstones
Ask for a certificate from a recognised gem testing laboratory — appearance alone can’t tell you whether a stone is natural, treated or synthetic.
