Luxury watches are distinguished by their high-quality materials, precision engineering, brand heritage, and often handmade craftsmanship. They typically use fine materials like gold, platinum, or high-grade stainless steel, and contain intricate mechanical movements.

Most manufacturers recommend servicing every 3-5 years for mechanical watches. Quartz watches may need less frequent servicing, typically every 4-6 years.

High-quality luxury watches from reputable brands often hold their value well and can sometimes appreciate over time. However, they should primarily be purchased because you appreciate the craftsmanship and design, not purely as financial investments.

Manual watches require daily winding by hand, while automatic watches wind themselves using the motion of the wearer's wrist. Both are mechanical movements, but automatics are more convenient for daily wear.

Check for: precise craftsmanship, proper weight, smooth movement operation, correct branding and serial numbers, and purchase from authorized dealers. When in doubt, have it authenticated by a professional.
