Pick of the Day

Second Hand for 50 Grand, 10.00pm, Channel 4

Here’s a new show for those who like the better things in life that aren’t being made anymore. People just can't get enough stuff.

It goes behind the scenes of a company that tracks down luxury second-hand items, going the extra mile to hunt down the exact handbags, watches and jewellery on their clients' wish-lists and find out the personal stories behind them.

First up, window cleaner Grant's dad wants to buy him a Cartier watch as a thank you for looking after him. (Must be good money in window-cleaning!)

Next up, Rebecca asks head of handbags Reece to scour the globe for an exact match to a stolen Prada bag gifted by her late mother.

Meanwhile, firefighter Hywell has received a watch from his Granddad. If the team can prove that it's genuine, then Hywell's life is about to change for ever.
