Ever heard of Benson of London watches. I have a gold coloured one with a stretch bracelet, it does not use a battery, just have to wind it once in the morning and once in the afternoon. Keeps perfect time. At the base it has Swiss Made. Just wondering. cheers

Never heard of them so Goggled and here is what I found, is one like yours there?
