About Bellefontaines' Jewellers Ltd

Bellefontaines' Jewellers was started in November 1946 by Dennis Dieu de Bellefontaine. Dennis' son, Gary Dieu de Bellefontaine, and his wife Mary, currently directors of the business.

As we look to the future, Bellefontaines' are now proud to present the next generation of Bellefontaines, Michael and William. They are currently being trained as they work within the shop. As they learn, please bear with them. If for any reason they are unable to answer all of your questions, please do not hesitate to ask to see Mary and we'll be very happy to advise you personally. 

We carry out watch and clock repairs, valuations, jewellery repairs and manufacture. We carry out ear piercing. Most of our repair work is carried out on-site in our workshops.  We have recently become an accredited service centre for Omega, Longines and Rado watches. However, we do use outworkers for certain specialised work.

We are here to help you choose that special gift for Christmas, christenings or any other occasion.
