Please note: this is a customised watch, meaning it may include components that differ from the original factory specifications. Customisation can vary widely, so we highlight the following possibilities for full transparency: Aftermarket parts The watch may include third-party components (such as bezels, dials, hands, crystals or gem settings) that are not produced by the brand owner. These parts are often added for aesthetic reasons, but are not considered original by the manufacturer. Original parts from other models Some components (e.g. dials or bracelets) may have been sourced from other genuine watches by the same brand. While these parts are authentic, they were not originally fitted to this particular model or reference, which may affect collectability or eligibility for manufacturer service. Non-original parts In some cases, customised watches may include parts that are neither original nor manufactured by the brand. These components can affect the watch’s value. We ask sellers to clearly mention such elements in their object description. We encourage all bidders to carefully review the photos and description before placing a bid. Keep in mind: customised watches may not be eligible for official service or warranty from the brand. All bids should be placed with full awareness of the customisation status described above.
