Larsson and Jennings is inviting the public to trade-in their old watches as part of an awareness-raising initiative for climate change charity Protect our Winters.
Anybody sending in an old watch, even if it is broken, will be sent a £65 voucher that can be put towards buying a new Larsson & Jennings watch from one of their stores or online.
All the watches that are donated with will be used by an artist who will transform them into a sculpture that will then be sold at auction to raise money for the Protect Our Winters charity.
The name of the artist and the date of the auction have not yet been confirmed, but old watches need to be sent in before May 26.
Only one watch can be submitted in return for a Larsson & Jennings voucher.
