Object description

Dial and Visual Appearance

The timepiece features a double-sunk white enamel dial with upright Arabic hour numerals and an outer railway minute track. Hours and minutes are indicated by blued steel spade hands, with an auxiliary blued pointer set into a recessed subsidiary seconds register at 6 o'clock. The dial is signed 'Waltham' over 'U.S.A.' beneath the 12 o'clock hour marker.

The dial is enclosed beneath a bevelled mineral glass. Visible casing elements include a polished yellow gold-tone bezel and an onion-style winding crown fitted with an oval bow positioned at 12 o'clock, characteristic of an open-face watch.

Reported Movement and Technical Specifications

The dealer description documents a 16-size damascened nickel bridge movement equipped with 19 jewels, gold train wheels, large gold jewel settings, a lever escapement, and a micrometer regulator. The vendor notes this model as an American railroad-grade approved configuration.

The movement is stated by the seller to be signed '19 Jewels, A.W.W.Co, Waltham, Mass, Riverside, 5 Positions, Adjusted' under serial number 17011327 and assigned a date of circa 1909. As the movement is not visible in the provided primary image, these specifications rely entirely on the seller's cataloguing.

Evidence for this section

  • “Movement – the high grade nickel bridge movement has gold train wheels, large gold jewel settings, a lever escapement and a micrometer regulator.”
  • “The movement is decorated with damascening and is signed “19 Jewels, A.W.W.Co, Waltham, Mass, Riverside, 5 Positions, Adjusted” 17011327 and is in 95% mint condition”

Open research questions

  • What specific Dennison grade or case serial number is stamped on the interior cuvette or outer case back?
  • Can direct inspection of movement 17011327 confirm the jewel count, balance type, and Riverside damascening pattern?
  • Are any watchmaker service marks or repair codes scratched into the inside of the case back or cuvette?
