This is an antique pocket watch featuring Roman numerals for the 12-hour time display and an additional 24-hour scale in red around the outer edge. The dial is marked “VÉRITABLE ROSSKOPF & C° PATENT J.M.”, identifying it as a Rosskopf & Co. timepiece — a popular maker of affordable, reliable pocket watches in the late 19th and early 20th centuries. A few notable details: • The smaller subdial at the bottom is a seconds counter, a typical feature of mechanical pocket watches. • The phrase “Ancre 15 Rubis” or similar (partially visible) likely indicates it’s a lever escapement watch with 15 jewels, a sign of decent quality. • The 24-hour markings suggest it might have been marketed for travel or military use, or for continental European users who preferred a 24-hour dial.
