SWISS TRIPLE CALENDAR SKELETONIZED POCKET WATCH: IDENTIFICATION

A late 19th-century hunter-cased pocket watch featuring a dual-sided display. The primary face consists of an enamel dial with Roman numerals, Louis XIV-style gold hands, and a small seconds sub-dial at the 3 o'clock position (sideways configuration typical of hunter cases). The reverse features a skeletonized movement visible through a glazed aperture, surrounded by a white chapter ring displaying a triple calendar complication with French day abbreviations (LUN, MAR, MER, JEU, VEN, SAM, DIM) and a 31-day outer date track.

Compare with other watches in the archive: Angus & Coote 'Faithful Lever' Pocket Watch (Elgin Movement) c.1915, Baume & Mercier Geneve Ladies Wristwatch c.1970s, Baume & Mercier Geneva Vintage Square Dress Watch c.1970.

CROSS-CULTURAL PARALLELS

  • •Traditional gift for military officers or professionals requiring precise date tracking before the advent of wristwatches.

Meaning Through Time

Late 19th Century

Symbol of technocratic status and high social standing.

Produced circa 1890-1910, this timepiece originates from the Swiss Jura region during a period of high demand for 'complication' watches intended for the French export market. The use of French day markings and the specific 'lepine' style bridge architecture under the skeletonization are characteristic of Swiss manufacturing centers like Le Locle or La Chaux-de-Fonds, which Heritage Auctions and Sotheby's have documented as hubs for such multi-function pocket watches in the late Victorian era.

  • Documented provenance valued
  • Active collector pursuit

Confidence Factors

  • Construction and screw-head profiles are consistent with late 19th-century Swiss manufacturing
  • Patina and wear patterns on the internal gears match the exterior case aging
  • Skeletonization was a popular boutique feature during the 1890-1910 period for higher-end complications
How does authenticity detection work?

WATCHMAKER'S ASSESSMENT

Vintage Watchmaker & Horology Specialist

Horologist

High confidence in the era and origin due to clear complication layouts and architectural markers, though lack of internal hallmark photos limits definitive brand attribution or metal purity verification.

KEY EVIDENCE

  • 1French calendar abbreviations indicate production for the Francophone market.
  • 2Skeletonized architecture reveals a standard Swiss lever escapement and bimetallic compensation balance.
  • 3Louis XIV hands are period-correct for the late 19th-century Swiss aesthetic.
  • 4Sideways sub-dial confirms hunter-case layout (Ref. Christie's 2021 pocket watch survey).
  • 5Screw-set jewels and tempered blue screws suggest mid-to-high grade production quality.

UNCERTAINTIES

  • •Internal case markings are not clearly visible in photos, preventing confirmation of gold purity (solid vs. gold-filled).
  • •The presence of hairlines on the enamel dial significantly impacts value for purist collectors.

WHAT WOULD IMPROVE CERTAINTY

  • →Open the inner dust cover (cuvette) to look for maker hallmarks or serial numbers.
  • →Perform a non-invasive lift of the movement to check for a brand signature on the pillar plate.
  • →Check for karat hallmarks (e.g., 0.585 or 0.750) on the inside of the case lids.

CONDITION & GRADE

Good (Grade 3)

Grading breakdown

Enamel hairline cracks and oxidation on the hands prevent a 'Fine' or 'Very Fine' grade, though the movement appears complete and the hinges show correct alignment.

Condition

The enamel dial shows a visible hairline fracture extending from the center toward the 7 o'clock mark. The calendar ring appears clean, but the blueing on the calendar pointer hand shows minor oxidation. The case edges show softening of the original profile, suggesting periodic polishing over the last century.

Weight & feel

Based on a diameter of approximately 50mm, the watch likely weighs between 90g and 110g, conveying a substantial density consistent with high-grade brass plates and a multi-layered case construction.

WATCH MARKET VALUE

$800 - $2,200

Updated: May 11, 2026

Who buys this

What increases value

  • •Functionality of the triple calendar complication

  • •Gold content of the case (14k/18k vs. gold-filled)

What lowers value

  • •Enamel dial hairlines can reduce value by 20-30%
  • •Mechanical parts for these early calendars are often custom-made, making repairs expensive

What makes top-tier examples

  • •Presence of a Moonphase complication alongside the triple calendar
  • •Signed movement by a known maker like Patek Philippe, Vacheron Constantin, or Audemars Piguet

Grade & condition

Smoothness of the calendar advancement mechanism, clarity of the enamel, and crispness of the movement engraving.
