Antique Key Wind Pocket Watch Identification - and ideas ???

[DeepseekerADS]

Over 30 years ago I purchased a silver Key Wind antique pocket watch, and I have been trying to identify this watch ever since. Since I'm on this site, maybe someone here can lend me some help. I took 3 pictures.

The hallmarks:



The back of the watch:



The Front of the watch:



All help will be greatly appreciated

Are the letters inside the two diamonds a J and an H?

It is definitely a J, and looks like an H but kinda weird H, like elongated?

What is the very top mark above the Lion Passant that looks like a T with something beside it? I think you need to remove the dust cover if your ever gonna know who the maker is. The marks on the case only tell half the story.

After looking at more of this style pocketwatch, I see they were made later than I had thought.
Was under the impression that fusees were mostly a pre 1850 design. thanks for the enlightenment

Looking at the Chester date charts it looks like it's 1899

It's missing the Sovereign head which dates the silver 1784-1890, the Q=1899
