The Vintage Wrist Watch Company has dated this piece to the 1900s.
The name 'goliath' was registered by Omega in 1892 for their giant pocket watches.
The watch has an Omega calibre 30''' 8-day stem-winding movement which is working nicely. The movement is protected by an inner hinged cover.

The watch itself measures 76mm diameter excluding the stem and the loop. The case is nickel and it is in good condition, as is the acrylic lens.
The dial is signed with the name of the original retailer, Debenham & Reed of London.
Original pin set hands.

The watch sits in its original leather covered case which transforms the watch into a bedside clock, and it has a battery operated light. The original light has been removed and replaced with a modern LED light but the fittings all sit in the original battery pack casing. The light can be a little temperamental but generally works fine when the clock is stood on a surface.

We see quite a few goliath pocket watches but it is unusual to see one in its original case with the light fittings still intact (abeit with modern replacement parts).
Going back to the dial, it is also signed MM&Co Patent. This relates to an 1895 patent for the construction of special plates for use in accumulators such as the one that would have powered the original light.
