Generate a photorealistic CGI luxury product hero image of a single chronograph wristwatch positioned vertically above a glossy near-black water surface at the instant of a circular crown-shaped water splash, in a 9:16 vertical portrait composition. The watch is centered horizontally with the dial center sitting slightly above the vertical midpoint. Camera angle is nearly straight-on frontal with a very slight downward perspective that keeps the upper case thickness and bezel surface visible. Watch face is square to camera; crown and pushers project toward frame-right. No human subject, no hand, no wrist, no table, no box, no secondary product present. No KlingAI watermark. No text overlay of any kind except watch dial markings. Replace any existing watermark with white uppercase logotype "PromptLabHub" positioned at the bottom-right corner in a clean modern sans-serif typeface.

Preserve the exact watch construction: broad faceted angular tonneau-style housing with roughly rectangular outer geometry and clipped/sloped corners surrounding a thick circular bezel. Outer case: silver-toned metal with mixed brushed/satin planar surfaces and narrower polished reflective edges. Side structure uses a darker blue-black material with small metallic screws visible along the perimeter. Bezel: thick circular silver-toned form with vertically brushed grain across the metal surface and multiple exposed round screw heads distributed around the perimeter at approximately 2, 4, 6, 8, and 10 o'clock positions.

Dial: very dark navy/blue-black base (hue ~205–215°, high darkness, moderate-to-high saturation), smooth semi-matte finish with subtle radial metallic light response — not mirror gloss. Large bold condensed white Arabic numerals at 12, 10, 8, and 6 o'clock. Remaining hour positions use polished metallic rectangular baton indices with bright luminous white inner fill. Fine white minute tick marks encircle the outer dial with longer white divisions at principal minute intervals. Central hour and minute hands are broad silver-toned forms with pale luminous center sections. Slim central chronograph/seconds hand present. Three circular chronograph subdials: left register at approximately 9 o'clock (dark blue field, white markings, thin light-colored hand), right register at approximately 3 o'clock (matching dark blue field, white markings, thin light-colored hand), lower register at approximately 6 o'clock (dark blue field, white scale markings, slightly larger visual presence). Small brand emblem beneath the 12 o'clock marker with white uppercase wordmark below it. All typography high-contrast white/silver. Crystal: clear transparent glass, restrained frontal reflection, dial details fully legible through crystal.

Crown at 3 o'clock position: large, dark/black form with ridged knurled perimeter. Upper chronograph pusher: silver-toned rectangular/faceted form above the crown, angled slightly upward-right. Lower chronograph pusher: matching silver-toned form below the crown, angled slightly downward-right.

Strap: deep navy blue (hue ~205–220°, medium-high saturation, medium-low brightness), rubber/silicone material with matte-to-satin surface finish. Parallel recessed longitudinal grooves run the full length of the visible upper and lower strap sections. Strap width is broad near the case attachment before tapering slightly away from the case. Buckle not visible.

Water construction: large crown-shaped circular splash rising around the lower third of the watch with two higher crests toward lower-left and lower-right. Numerous suspended water droplets spread across the frame with densest concentration around the splash zone and mid-background. Droplets are transparent with sharp white specular points and strong cyan-blue internal reflections (hue ~190–200°). Glossy near-black water surface covers the lower half of the composition. Concentric circular ripples radiate outward from the watch impact point, strongest toward frame-right and lower-left. Strong inverted reflection of the watch visible beneath the splash, becoming progressively softer and more distorted toward the lower frame edge — reflection shows blue-black dial/strap tones with white-silver and cyan metallic highlights.

Background: three depth layers. Layer 1 — immediate water plane and splash in sharp focus. Layer 2 — mid-depth airborne droplets with partial focus and bright cyan/white highlights. Layer 3 — deep charcoal-to-navy blurred field (hue ~210°, low-to-medium saturation, 5–15% brightness) with dozens of circular and elliptical bokeh discs ranging from charcoal grey and cool white to saturated cyan-blue (hue ~190–200°); largest soft bokeh discs concentrated in upper-left, upper-center, and upper-right zones. Background considerably darker than the watch; brightest values restricted to metallic surfaces, splash highlights, and droplets.

Lighting: primary key light from approximately 10–11 o'clock position, soft-to-medium quality, neutral-cool (~5000–5600 K), producing broad elongated white highlights across brushed silver bezel planes and narrow high-intensity specular streaks along polished case edges. Strong cyan-blue edge/accent illumination from frame-left and lower side (~6500–8000 K visual feel) forming rim separation along both sides of the case and strap against the dark background. Narrow cool white secondary highlights along frame-right metal surfaces, crown hardware, and water droplets. Crystal reflection controlled and low-opacity — dial fully visible. Water highlights: hard pinpoint specular reflections combined with bright cyan transmitted light. Fill at approximately 25–35% on shadowed metal zones — details remain visible, not crushed to black. Deepest shadows beneath the bezel, around the lower case, between strap grooves, and within the black water surface.

Color grade: cool high-contrast luxury commercial product grade. Dominant palette — blue-black (~210°, 5–15% brightness), deep navy (~205–220°, 15–30% brightness), cyan (~190–200°, 55–90% brightness), neutral silver (low saturation, 55–90% brightness), cool white highlights (90–100% brightness). Saturation concentrated in cyan and navy. Split tone: shadows lean deep navy/blue; highlights alternate between neutral silver-white and cyan-blue. Overall temperature cool (~6000–7000 K visual balance).

Camera feel: approximately 70–100mm equivalent focal length, f/2.8–f/4, selective shallow-to-moderate depth of field. Sharpest focus on dial, bezel, central case, and front splash crest. Background droplets rapidly defocus into bokeh. Grain level 1/10 — essentially clean digitally polished output. Post-processing level 8/10: strong contrast shaping, precise metallic highlights, cyan accent grading, enhanced water clarity, polished commercial finish.
