The Zenith Defy Skyline Skeleton White Surfer is the third and final Zenith x Time+Tide Surfer Trilogy watch. Reference 49.9309.3620/85.I001 is a 100-piece limited edition pairing a 41 mm white ceramic case and bracelet with a gradient-blue openworked dial and the automatic El Primero 3620 SK movement.
What makes the White Surfer the trilogy’s finale?
ZENITH describes the White Surfer as the third and final chapter of its collaboration with Time+Tide. It follows two Night Surfer editions: Time+Tide identifies the 2021 DEFY Classic Skeleton Night Surfer as a 100-piece limited edition, followed by a DEFY Skyline Skeleton Night Surfer El Primero limited to 200. Those details come from the collaboration’s own launch coverage, rather than an independent comparative review. ZENITH’s product page and Time+Tide’s launch article frame the White Surfer as the trilogy’s conclusion.
The final edition reverses the earlier Night Surfer’s dark visual language with white ceramic and an icy blue dial. ZENITH CEO Benoît de Clerck described the collaboration as “not just continuing a story, we’re elevating it,” in Time+Tide’s launch article.

How the bracelet and strap change
Time+Tide says the White Surfer comes with both its integrated ceramic bracelet and patterned rubber strap. The listing describes a quick-change system that lets the wearer switch between them without tools. It does not provide a separate technical description of the mechanism or a measured change time.

On 7 October 2026, Time+Tide’s US product listing displayed a price of $19,600 USD and marked the watch “Out of stock.” Its UK listing displayed €20,500 and was also marked out of stock at that observation. These are regional storefront listings, not a single global price; taxes, duties and delivery treatment may differ. The listings do not establish current inventory elsewhere.
Time+Tide’s launch article said the watch would be available through select ZENITH boutiques globally from 11 July at 12:00 UTC and through Time+Tide, but the cited passage does not specify the year. That launch notice does not indicate present availability.
