E.Duncan London verge pocket watch.

[blanthauer]

Hi
Please help me with dating and silver hallmarks.
How old is it?

Hi blanthauer, and welcome to the Forum,

The case hallmarks show that it was assayed in the London office in 1804, and the case maker was Matthew Need at 2 Castle Street, City Road, London.

I can't find a reference to an E Duncan, but this may well be a retailer. The movement has an unusual balance cock design, particularly the foot, and the steel plate, ("coqueret"), is also seldom seen on English movements. The dial numerals with minutes superimposed at the quarters is something I have not seen before.

Do you have any provenance for it?

Regards,

Graham

Appears to be London 1804 according to the hallmarks. That's a unusual balance cock. Very beautiful. Any side pictures of the movement?
Regards,
Logan

Me and Graham are right on track! LOL!

Hi
Thanks for your help and time.
The watch was bought yesterday and I haven't any provenance for it.
I have a question- what is the part marked in white arrow? Is this for chain?

Hi blanthauer,

No pictures I'm afraid. I suspect that you're trying to post images that are too large for the software to re-size; up to around 2mb should be OK, now that the limits have been increased.

Regards,

Graham

Hi blanthauer,

Still nothing! When you reply, select the "Go Advanced" button which allows you to preview your post before committing it.

How are you adding your images?

[EDIT] Just tried in IE emulation and I can now see 4 image placeholders which give an "invalid image" message.

Nice watch!

The dial is unusual too: I do not remember a dial with th 15, 30, 45, 60 minute numbers set in this way.

Those pictures are excellent; now your question - which part are you referring to?

Oooh, that's one I can answer .... it's a Tompion regulator wheel

Thanks everybody for your help

Hi blanthauer,

Turning the disc changes the effective length of the hairspring, and thus the frequency of the balance.

This is what's underneath the slide plate:
