This article targets buyers with high‑standard requirements for gold‑cased watches, using the Patek Philippe Nautilus 5724 as the reference timepiece.

As is well‑known, gold‑plated watch cases tend to fade. Their colour retention rarely lasts more than three years, and discoloration can develop with regular wear. This gold finish is achieved through electroplating. Of course, gold‑filling treatment is unnecessary if you frequently switch between different watches.
If you have a sufficient budget and expect the gold casing to retain its hue for five years or longer, gold‑filling for the watch case is a viable option.

Two gold‑filling service tiers are currently available: one with a 3‑year fade‑resistant guarantee and another with a 10‑year guarantee, featuring 30 cc and 50 cc gold‑layer thickness respectively. You may select according to your budget. Pricing starts above 2000, and the final cost depends on prevailing gold rates and the specific watch model.

Service guarantee: Within the warranty period, the case will receive complimentary re‑gold‑filling should significant fading occur. Neither polished nor brushed original surface finishes will be altered during the gold‑filling process. Now take a look at the finished‑piece presentation of this watch.
