Object description

Identity and Case Construction

Documented as Silvana reference 13002, this manual-winding gentleman's wristwatch is assigned case number 576 961 and dated to circa 1940 by the catalog. The case is constructed from stainless steel with a vertical "tonneau" shape and a snap-on case back.

The catalog records dimensions of 39.2 by 32 mm, a bezel diameter of 32 mm, and an approximate total weight of 34.9 grams. Direct observation notes two pushers and a fluted winding crown situated along the right side of the case.

Evidence for this section
  • “Reference 13002”
  • “Case No. 576 961”
  • “Year circa 1940”
  • “Stainless steel, manual-winding, vertical “tonneau”-shaped, gentleman’s wristwatch, snap-on case-back”
  • “Dimensions 39.2 x 32 mm.”
  • “Diameter 32 mm. (bezel)”
  • “Weight 34.9 gr. (approx.)”
  • “Two pushers and a fluted winding crown situated on the right side of the stainless steel case”

Dial Configuration and Observed Inconsistencies

The watch features a champagne-colored dial marked with suspended Arabic numerals at 2, 4, 8, and 10 interspersed with dots, with the dial bearing a Silvana signature. The catalog describes the hands as original.

An internal inconsistency exists in the catalog description: the text lists subsidiary seconds at 9 o'clock and a 30-minute counter at 3 o'clock, whereas visible observation confirms dual auxiliary dials arranged vertically at 12 and 6 o'clock on the champagne-toned dial.

Evidence for this section
  • ““champagne” colour dial with suspended Arabic numerals (2-4-8-10) and dots”
  • “Signature dial”
  • “HANDS Original”
  • “subsidiary seconds at 9 and two horological complication: · 1/8 second chronograph (activated by the two round-shaped push-pieces located on the case-band) · Half-instantaneous 30-minute counter (subsidiary dial at 3 o’clock)”
  • “Vertically arranged dual sub-dials positioned at 12 and 6 o'clock on a champagne-toned dial”

Reported Mechanism and Catalog Conditions

According to the auction listing, the movement is an unnumbered 17-jewel caliber 12''' 1/2 based on the Venus 170 by Berret & Schmitz of Moutier. It is reported to feature a 1/8-second chronograph activated by two round push-pieces on the case band and a half-instantaneous 30-minute counter.

Movement and inner case back photographs are not present in the source, leaving internal parts and finishing unverified. The catalog marks the movement with an overhaul recommendation at the buyer's expense and explicitly disclaims guarantees regarding movement function, precision, water resistance, or mechanical completeness.

Evidence for this section
  • “Caliber 12’’’ ½ (based on Venus 170 by by Berret & Schmitz, Moutier, Bernese Jura), 17 jewels”
  • “Movement No. unnumbered”
  • “1/8 second chronograph (activated by the two round-shaped push-pieces located on the case-band) · Half-instantaneous 30-minute counter”
  • “Overhaul recommended, at buyer's expense”
  • “we guarantee neither the functioning nor the precision of the movement, nor the water-resistance of the case. In addition, please note that movements, parts of mechanisms or cases may be incomplete.”

Open research questions

  • What specific caliber markings and signatures appear on the unnumbered movement plates?
  • Does the interior of the snap-on case back bear Silvana manufacture stamps or case maker hallmarks?
  • Given the catalog's 3/9 o'clock textual error versus the vertical 12/6 o'clock layout, which specific sub-dial corresponds to continuous seconds and which to the chronograph minute counter?
