Custom client-supplied watch modification service: 18K gold-plated upgraded version inspired by the Royal Oak 26240 black dial design, 41mm case size with a 4401 automatic chronograph movement.
This service features an upgraded 18K rose gold plating process with a warmer yellowish tone similar to boutique-grade finishing standards. The enhanced plating technique is designed to improve common issues found in standard white gold, rose gold, and gold-tone coatings, such as oxidation, fading, and discoloration over time.
By using proprietary plating technology, the watch achieves a more stable metallic appearance, delivering a visual effect closer to solid 18K gold while significantly improving long-term color durability and wear resistance.
The service provider specializes in high-end customization including:
18K / 24K gold plating upgrades
Post-set diamond customization
Solid gold component customization
Luxury watch refinishing and restoration services
Each piece is delivered as a customer-commissioned finished product, with real production samples available for reference and evaluation.
