The prompt
Design a realistic and fully detailed wristwatch CAD model with the following specifications: The watch case diameter must be 40 mm. The total strap length must be 200 mm (excluding the buckle mechanism if necessary). The watch should have a round case with a clean and modern design suitable for manufacturing. The dial (watch face) must be white, while the hour and minute hands must be black. Display the hands at approximately 10:10 for an aesthetically pleasing appearance. Include all 12 hour markers on the dial. Watch Strap Requirements Design a realistic black wrist strap with appropriate width and thickness for a 40 mm watch case. The strap must consist of two separate pieces connected to the watch case through standard lugs. Include a functional-looking pin buckle clasp mechanism, consisting of: Buckle frame Pin (tongue) Strap keeper loops Multiple adjustment holes on the opposite strap side The strap should be designed as an interlocking/pass-through fastening system that can be assembled realistically.The strap should have the following specifications: Total strap length: 200 mm Strap color: Black Realistic strap width and thickness suitable for a 40 mm watch case. The strap must consist of two separate pieces attached to the watch case using spring bars or lug connections. Include multiple adjustment holes on one side of the strap. Include a complete and realistic buckle assembly on the opposite side, consisting of: Buckle frame Buckle pin (tongue) Strap keeper loops Proper pass-through fastening mechanism The strap should be designed so that it can realistically pass through the buckle and be fastened around a wrist. Add appropriate fillets and rounded edges to improve manufacturability and realism. The buckle and strap dimensions should be mechanically plausible and proportional to the 40 mm watch case.
