This watch promises to be one of real interest, and though not all the facts fit as yet I think they can be solved.
Let us then start with the usual, and go from there.
The hallmarks are for a watch of this age are very good, the crowned Leopards head nice and clear, and so the Lion Passant, the letter "J" not often used in English hallmarks, for the year 1764. Central to these the letters "IB for John Bingly, 13 Little Britain, London.
So is the case original to the watch, I hope I can say yes, but first let us take a look at the movement.
These photographs are from the sale, so I will publish better ones when the watch arrives. What we are looking for hear are points that would indicate a watch of 1764, disregarding the signature at this time because the name Willian Lloyd is a little more than complicated.
The cock foot is pierced, the cock its self is known mostly as "Laced-Edged", Then there are the so-called Georgian Pillars. All these indicate a date between 1759 to 1780 according to Cedric Jagger´s book " The Artistry of the English Watch"
I am going to leave it here, for I think the name, William Lloyd, will take some time to sort out..........Till Later,
