Object description

Case and Dial

The watch is housed in an 18K yellow gold case measuring 37.50mm excluding the crown, featuring a total lug-to-lug length of 44mm. The case incorporates a cuvet positioned between the movement and the case back. External engravings on the back of the case denote the material purity and technical identifiers, specifically "18K - .750 – Hammer 147 - 54".

The salmon-toned dial is characterized by applied gold Arabic numerals and baton-style hour markers. It features a decorative central guilloché pattern and two sub-registers located at the 3 o'clock and 9 o'clock positions, used for the chronograph minute counter and continuous seconds, respectively. A tachymeter scale printed in blue and a telemeter scale in red occupy the outermost perimeter. The hands are gold-toned and follow a Dauphine profile.

Evidence for this section
  • “The watch has a 18K yellow case with engraved outside “18K - .750 – Hammer 147 - 54””
  • “The watch has a cuvet between the case and movement”
  • “The watch has two sub dials, minutes at 3 o’clock and seconds at 9 o’clock”

Movement and Performance

Internal function is provided by a Landeron caliber 54, a manual-winding movement designed as an ebauche for assembly. This movement contains 17 jewels and oscillates at a frequency of 18,000 A/h. It provides a power reserve estimated at 41 hours.

The movement is categorized as an assembly component rather than a manufacture-produced caliber, reflective of the mid-20th-century "Chronographe Suisse" era production model where specialized suppliers provided the underlying ebauche mechanisms for various watch brands.

Evidence for this section
  • “The watch comes with a manual winding Landeron with caliber 54 and 17 jewels”
  • “Manual winding Landeron movement with caliber 54, 17 jewels and 18,000 A/h. The power reserve is approximately 41 hours”

Brand and Provenance

Coresa operated during the mid-20th century, focusing on the production of mechanical chronograph wristwatches. The company functioned primarily as an assembler, sourcing movements from established suppliers rather than manufacturing components in-house.

The watch is reported as having been serviced by the vendor, though the documentation for this service is not specified beyond the listing details. It is sold without original box or paperwork.

Evidence for this section
  • “Coresa operated as an assembler rather than a full manufacture”
  • “Like many brands of the "Chronographe Suisse" era, they sourced reliable, mass-produced ebauche (blank) movements from major Swiss suppliers”
  • “The watch has been serviced”

Open research questions

  • What is the specific manufacturer or meaning of the "Hammer" mark found on the case back?
  • Does the serial number "147" correspond to a specific production batch for Coresa chronographs from this era?
