Act as a graphic designer and create a logo proposal for the brand "LEGLEU", a company specialized in unique and customizable high-quality watches for men and women from 18 to 60 years old. The logo must include the brand name "LEGLEU" with the tagline "personalized perfection" below it. Feature multiple typography options, including cursive and block (sans-serif and serif) styles. Do not include any images related to watches; focused solely on typographic presentation. The logo must convey sophistication, exclusivity and timelessness. In addition, it creates a minimalist isotype that complements the typography. Use a refined color palette suitable for a luxury brand. Ensure the design appeals to a global audience and emphasizes the brand's commitment to high quality and customization.
