This is a custom 5724G Nautilus (white gold case) with a bezel set with German‑imported D‑color moissanite diamonds. D‑color is the highest grade (colorless), so these stones will be super bright and white. Moissanite gives you diamond‑like sparkle at a fraction of the cost of natural diamonds.
The 5724G is already a diamond‑bezel model from Patek (factory version uses natural diamonds). This custom version swaps in high‑quality moissanite to keep the bling but lower the budget. Perfect for someone who wants the look of a full diamond‑bezel Nautilus without paying for real stones.
