JACOB&CO Premium Men's watches

Case: Premium tonneau-shaped case with smoothly curved sides, polished silver/white-metal construction, extremely precise machining, and a double-row diamond-set bezel.

Dial: Fully skeletonized transparent dial with the mechanical components clearly visible. Show intricate gears, bridges, screws, balance assembly and architectural movement details. Use silver, black and subtle blue accents. Keep the center highly detailed and technical.

Movement: High-end mechanical skeleton movement with visible gears and bridges. The movement should look genuinely engineered, finely finished and three-dimensional—not like a printed graphic. If a tourbillon is shown, make the tourbillon mechanism mechanically coherent and correctly positioned.

Crystal: Clear anti-reflective sapphire crystal with realistic reflections while maintaining excellent visibility of the movement.

Strap: Premium black rubber strap with a clean luxury finish and realistic texture.

Presentation: Place the watch on a male wrist wearing a clean cream/white luxury shirt. Maintain the same wrist angle and close-up composition as the reference. Use a clean white studio background, soft diffused lighting, realistic skin texture and premium jewelry/watch photography.

Quality: Photorealistic, ultra-detailed, sharp macro photography, realistic metal reflections, individually visible gemstones, accurate mechanical depth, premium Swiss-watch craftsmanship, natural shadows, no distortion, no extra fingers, no malformed components, no duplicate gears.
