The prompt
Create ONLY the watch case for the reference design. Design a premium modern wristwatch case with an EXACT outer diameter of 38.00 mm. Material: 316L stainless steel. The case should have: - 38.00 mm round case diameter - black main case body - rose-gold accent surfaces - fixed numbered 60-minute bezel - integrated short lugs - 20 mm lug/strap width - crown at 3 o'clock - removable screw-down caseback - circular opening for the dial - crystal seat at the top - movement cavity on the inside - clean premium geometric surfaces - realistic CNC-machining fillets and chamfers The case must be designed as separate editable CAD solids: 1. Main case body 2. Fixed bezel 3. Caseback 4. Crown Do NOT create the dial, hands, strap, movement or bracelet. Do NOT guess the Miyota 2035 mounting dimensions. Leave the movement cavity as a configurable feature that can be dimensioned later from the official Miyota 2035 technical drawing. Make the geometry suitable for CNC machining in 316L stainless steel. Export as STEP.
