Illustrate a close-up view of a luxurious mechanical handwatch, emphasizing its minimalist design and high-quality materials. The watch should feature a brushed titanium case with a diameter of 40mm, showcasing a seamless integration of form and function. The royal blue dial should be smooth and matte, adorned with minimalist hour markers in a subtle silver tone, enhancing the watch's elegance. The hour and minute hands should be crafted in a matching royal blue hue, while the second hand should be a distinct, vibrant shade of azure, ensuring it stands out for easy readability. Set the watch against a dark gradient background that transitions from deep charcoal at the top to a rich black at the bottom, enhancing the watch's sophistication. Employ soft diffused lighting from a 45-degree angle above the watch to create gentle illumination that highlights the watch's features, showcasing the craftsmanship and attention to detail without harsh shadows. Utilize a macro lens (100mm) with a shallow depth of field (f/2.8) to focus sharply on the intricate details of the watch while softly blurring the background, enhancing the luxurious feel. Set the ISO to 100 to maintain clarity and detail in the watch's components. In post-production, apply subtle reflections on the watch's surface to emphasize its craftsmanship, and enhance the saturation of the blue tones to create a striking visual impact. The final image should resonate with an audience that values both style and functionality in their timepieces, capturing the essence of modern luxury.
