While it is true that luxury watches appreciate in value, it is impossible to say for certain which watches will increase in value. However, some of the factors that can affect the value of a watch include:
The brand: Some brands are more sought-after than others, and their watches tend to appreciate in value more quickly.
The model: Some models are more rare or desirable than others, which can also affect their value.
The condition: As with any investment, the condition of the watch is important. Watches in mint condition will fetch higher prices than those that are worn or damaged.
The demand: The demand for luxury watches can fluctuate, so it's important to buy a watch that is in high demand.
