Heuer Carrera Reference 2448N Chronograph

Partially verified

This Heuer Carrera reference 2448N is a manual-wind chronograph wristwatch presented in an 18K yellow gold case. The watch features a matte black dial with applied gold baton markers, gold hands, and a triple-register layout. It is powered by a Valjoux 72-family movement. The dial is dual-signed with the name “E. G. Schaubert”. The watch was commissioned as a retirement gift by Sears, Roebuck & Company for Everett G. Schaubert, a senior executive. The case includes Heuer-Leonidas SA signatures and Swiss 18K/0.750 hallmarks on the interior of the case back. It is fitted with original pump-style pushers and crown. An authentic Heuer-branded gold-plated buckle, acquired later, is also included. The timepiece was serviced in May 2026.

Object description

Case and Dial

The watch is housed in a 35 mm 18K yellow gold case featuring faceted lugs. The interior of the case back bears the Heuer-Leonidas SA signature and Swiss 18K/0.750 hallmarks. The exterior is fitted with its original crown and pump-style chronograph pushers.

The matte black dial is configured with three subsidiary registers and applied gold baton markers with matching hands. The dial carries the Heuer shield and the name “CARRERA” at the 12 o’clock position, and is further factory-signed with the name “E. G. Schaubert”.

Evidence for this section
  • “The 18K case carries correct Swiss 18K/0.750 hallmarks and Heuer‑Leonidas SA signature inside the back”
  • “the dial is factory dual‑signed with the name “E. G. Schaubert””

Movement

The timepiece is powered by a manual-wind chronograph movement from the Valjoux 72-family. This movement is noted for its column-wheel actuation. The auction description reports that this caliber was also used in Rolex Daytona models of the same period.

The movement remains in working order, having undergone a full service in May 2026, which the vendor confirms maintains the reliability of the mechanism.

Evidence for this section
  • “Inside beats Heuer’s trusted Valjoux 72‑family manual‑wind chronograph movement”
  • “delivering crisp column‑wheel actuation and proven reliability”
  • “Recent full service, May 2026”

Provenance and History

This watch functioned as a bespoke presentation piece for Everett G. Schaubert, a senior executive at Sears, Roebuck & Company who managed the Goodyear Tire account. The watch was presented to him upon his retirement.

The vendor reports that the presentation occurred in 1967 or 1968, which corresponds with the serial range for this reference. This history is cited as evidence of the dial's originality and specific printing.

Evidence for this section
  • “the watch was presented by Sears, Roebuck & Company as a retirement gift to Everett G. Schaubert”
  • “The presentation in 1967/68 aligns perfectly with the serial range and period of the reference”
  • “this well‑documented story lends the watch notable corporate and motorsport provenance”

Open research questions

  • What is the specific serial number of the case back?
  • Does the serial number confirm a production date closer to 1967 than the early 1960s?
