London Watchmaker Rivanail ??

[Burkhard Rasch]

an intertesting watch found its way into the workshop of my watchmaker : it´s an 3rd quarter 18th cent. verge of classical design , completely unjeweled , with a Tompion silver regulator disc , a plain white enamel dial with black roman numerals and a seconds subsidiary dial above the VI ( 1-60 ) and a date subsidiary (1-31) below the XII .
The movement is signed S. Rivanail 1811 London , the dial bears S and p left and right from the center. Silver standard case of english origin (sorry I forgot to look up the hall-marks ) Any ideas about the maker?
Sorry , no pics at the moment , perhaps later...
TIA

Wow, neat gilding, fancy pillars, overall engraving, and a calendar to boot. Thanks for the share.

correction : when I look at the pics I think the balance might be jeweled . Thanks for Your kind comments , any idea about the maker or the decade the watch was made in? Any suggestions wellcome.

Something about it, style, engraving etc. makes me think it may be a continental watch signed London.

Geneva watchmaking was very present in London and imported many products and I remember that there was an exchange of students between the U.K. and Geneva.

I agree. Appears to be genuine hallmarked case - London 1808, MN Matthew Need, 22 Featherstone Street, possibly exported to the continent, movement fitted with fictitious London name & exported to America.
