While comparing factory-set vs customized watches, many investors prefer factory original models. It is because of its original engineering, long-term value and brand integrity. Here are the reasons included in our Luxury Watch Product Guide for collectors that help you understand the reasons why to prefer plain watches over customized watches.
Warranty Protection
A major benefit of a factory-original watch is that it maintains the manufacturer warranty. Adding diamonds to a dial requires opening the watch case: if this occurs, the original brand warranty is voided, and the manufacturer will no longer cover official repairs.
Better Long-Term Investment
A plain watch holds its value better than customized ones. The diamond additions enhance visual appeal, and customized watches depreciate assets. The Resale value of customized watches is lower than plain watches. So, investors can prefer the plain watches as the brand produced them, and make it a long-term investment option.
Authentic Craftsmanship
The diamonds added to customized watches are aftermarket modifications. It means they are installed after the watch leaves the manufacturer and does not remain factory sets now. Due to this, it is a less authentic piece than plain watches. So the people who want to buy authentic craftsmanship can purchase plain watches.
Preserved Water Resistance
The plain Statement jewelry watches Indianapolis are designed with precise seals and protect the internal movement from dust and moisture. When a watch case is opened for aftermarket diamond installation, the factory seal is broken. As a result, the timepiece usually loses its certified water resistance and no longer meets original manufacturer standards.
Safer Customization
Those who still want personalization touch can add diamonds to watches. But plain watches are the best option to maintain integrity of the movement and reduce the risks of damaging components.
