DESCRIPTION:
EPW - Charles Frodsham, 84 Strand, London, keyless pocket chronometer with spring detent escapement, free-sprung balance with extremely unusual hairspring having a triple overcoil, 56mm, massive 18K gold original HC with engraved initial monogram to front and family crest to rear, gold cuvette, white enamel SS dial, SW-LS with setting lever pressed inward and held while crown is turned, spring detent escapement with capped escape wheel, free-sprung balance with diamond endstone and triple overcoil hairspring, 20-21J, gilt mvt, s#04144 with matching serial number to dial and within case. Gross weight of assembled watch 120.8 dwt (188.0 g). A truly exceptional piece for the pocket chronometer collector, both for its enormously heavy gold case and for its extremely unusual hairspring having a triple overcoil which gives it an initial visual impression almost as being two hairsprings stacked atop one another.
