Aero Watch Keyless Pocket Watch with Gamet Enamel

Partially verified

This keyless pocket watch, manufactured by Aero Watch of Neuchatel, Switzerland, and retailed by Jeangold, Horloger, dates to circa 1970. The case back is decorated with cast foliate scrolls, while the hinged front cover displays a polychrome painted enamel flower spray signed by the artist Gamet, framed by a royal blue enamel border adorned with paillons. The white dial presents radial Roman numerals, outer minute divisions, red 24-hour markers, and a subsidiary seconds dial, all driven by a 17-jewel, rhodium-plated movement. Technical features of the movement include a straight-line lever escapement, monometallic balance, self-compensating flat balance spring, micrometer regulator, and an incabloc shock absorber. The watch is completed by blued steel spade hands.

Object description

Case and Exterior Decoration

The watch is presented in a three-body, bassine-style gold-plated case measuring 48 mm in diameter. The exterior finish consists of a brushed surface combined with a detailed cast foliate band that encircles the case edge. The pendant and bow also feature matching cast foliate scrollwork, extending the decorative theme to the attachment point.

The hinged front cover serves as the primary visual focus, featuring a hand-painted floral spray on enamel signed by the artist Gamet. This central design is surrounded by an outer border of royal blue enamel, further embellished with paillons, which are small decorative metal foils embedded within the enamel. The case back is similarly decorated with cast foliate scrolls, maintaining consistency with the overall ornate aesthetic of the timepiece.

Evidence for this section
  • “Three-body, bassine, brushed, cast foliate band, pendant and bow, the back cast with foliate scrolls”
  • “hinged front cover with a painted on enamel flower spray signed "Gamet", outer royal blue enamel border with paillons.”

Dial and Hands

The dial is rendered in white and follows a classic layout with radial Roman numerals indicating the primary hours. To provide additional functionality, the dial includes outer minute divisions and a distinct set of red 24-hour numerals. A subsidiary seconds dial is integrated into the lower portion of the display.

The time is indicated by blued steel spade hands, which contrast against the white dial background. The signature 'Jeangold Horloger' is present on the dial, denoting the retailer of the watch, distinguishing it from the 'Aero Watch S.A.' signature found on the case.

  • “Dial signed Jeangold Horloger, case signed Aero Watch S.A.”

Movement and Technical Features

Internally, the watch is powered by a 17-jewel movement that is rhodium-plated for protection and appearance. The caliber utilizes a straight-line lever escapement and includes a monometallic balance paired with a self-compensating flat balance spring to regulate the timekeeping.

To ensure durability and precision, the movement is equipped with an incabloc shock absorber and a micrometer regulator, which allows for fine adjustment of the timing.

Evidence for this section
  • “rhodium plated, 17 jewels, straight line lever escapement, monometallic balance, self compensating flat balance spring, incabloc shock absorber, micrometer regulator.”
  • “Overhaul recommended, at buyer's expense”
