Object description

Dial and Hands

The watch features a beige sector-style dial with black concentric rings and a railway-track minute scale. It includes painted Arabic numerals at the 12 and 6 o'clock positions.

Case and External Construction

The timepiece is housed in a stainless steel, two-piece case featuring a screw-down caseback and pump-style pushers. The dimensions are reported as 38 mm in diameter (excluding crown) and 45 mm lug-to-lug.

The seller states that the movement and case are signed and numbered; however, these markings are not visible in the provided source imagery.

Mechanical Specifications

The chronograph is reported by the seller to be powered by a Valjoux 22 manual-winding caliber, which utilizes a column-wheel mechanism.

Open research questions

  • What specific alphanumeric serial number is present on the caseback?
  • Are internal case markings or movement serial numbers available to verify the claim that the movement is signed?
  • Is there any documentation or service history to support the 'near-new' (NOS) condition claim?
