The black-dial 50529 pairs white gold plating with a dark guilloche surface for the most formal expression of the Cellini Dual Time. The cool white metal against the black dial creates sharper contrast than the Everose variants, and the second timezone subdial at 6 o’clock reads clearly against the dark background — making this the preferred reference for travellers who dress for evening events across multiple time zones.

The 50529 Up Close: Case, Dial and Bracelet
At 39mm in white gold plating, this Cellini carries the same refined dimensions as every piece in the modern Cellini collection. The white gold plating fluted double bezel reflects light with a cooler, more platinum-like sheen than its Everose counterparts, pairing naturally with the dark dial.
The black guilloche adds mechanical depth — visible only when light catches the repeating pattern beneath the lacquer. Applied white gold-plated indices and dauphine hands stand in high relief against the dark surface for immediate legibility. The second timezone subdial at 6 uses white and blue sectors for AM/PM distinction.
A black alligator strap in tone with the dial completes the stealthy profile, while the concealed white gold plating deployant adds invisible security at the wrist.
Movement Options: Swiss vs Japanese
Choose between two proven automatic calibers for the dual time complication:
- Swiss Automatic — 28,800 vph frequency with approximately 70-hour power reserve. The second timezone adjusts via pusher at 9 o’clock in independent one-hour increments.
- Japanese Automatic (Miyota) — 21,600 vph with 42-hour reserve. Full dual-time functionality with globally accessible service centres.
Manual winding and hacking seconds are standard on both options.
