Cortebert 660ft/200m Chronograph Diver Watch

This is a vintage-style Cortebert chronograph diver's wristwatch featuring a dark brown or 'tropical' sunray dial. The watch is constructed with a robust stainless steel tonneau-shaped case and is paired with a matching three-link oyster-style stainless steel bracelet. The dial features three sub-dials (registering small seconds, minutes, and a 24-hour hand), rose gold-toned hardware for the baton indices and pointed hands, and a date window positioned between 4 and 5 o'clock. The dial is marked with the Cortebert star logo and a water resistance rating of '660ft/200m'. It is equipped with a black rotating timing bezel with a 60-minute scale. Condition-wise, the timepiece shows significant signs of wear and age. There are heavy scratches and scuffs visible on the metal bracelet, particularly on the link surfaces, as well as distinct wear on the crown. The bezel shows some fading and minor chipping along the edges. The crystal appears to have light surface scratching and a blueish reflection suggest an AR coating. The overall aesthetic suggests a late 20th-century or modern homage to mid-century dive chronographs, likely utilizing a quartz movement given the dial layout. The craftsmanship is utilitarian, aimed at tool-watch functionality.

Based on my visual examination of the provided images, this item appears to be a modern-era Cortebert chronograph diver, likely dating from the 1990s or early 2000s, rather than a vintage mid-century piece. While the Cortebert brand has a prestigious history dating back to 1790 (famously supplying movements to Rolex and Panerai), the brand went defunct in the 1970s. This specific watch represents the later resurrection of the name, usually associated with mass-market manufacturing rather than high horology. The dial layout—specifically the configuration of the sub-dials and the angled date window at 4:30—strongly indicates a quartz movement, likely a Japanese Miyota OS20 or similar robust but inexpensive caliber. The condition is heavily used; I note significant scratching on the oyster-style bracelet and tonneau case, consistent with daily wear as a 'beater' tool watch. The bezel insert shows visible fatigue and edge wear. The 'tropical' brown sunray dial is aesthetically pleasing but appears to be a deliberate design choice rather than natural patina. In the current market, collectors distinguish sharply between pre-1970s mechanical Corteberts and these post-quartz crisis revivals. There is minimal collector demand for the modern quartz iterations, placing this firmly in the category of a functional used timepiece rather than an investment-grade collectible. Value is derived primarily from its utility as a 200m diver and its aesthetic appeal. To confirm the exact movement and rule out a generic replacement, I would need to open the case back. Without that, valuation is based on it being a standard modern quartz fashion watch bearing a heritage name.
