Design
- 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.

- 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.
- 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.
