Tennis player Alexander Zverev spotted wearing a Jacob & Co.

Tennis champion Alexander Zverev wore Jacob & Co.'s The World Is Yours Dual Time Zone Tourbillon during his historic ATP World No. 1 trophy presentation at the 2026 Rolex Paris Masters. The 43mm rose gold watch dominated his wrist as he claimed the ranking for the first time in his career, pairing athletic excellence with haute horlogerie craftsmanship on one of tennis's biggest stages.

The World Is Yours Tourbillon exemplifies Jacob Arabo's design philosophy through its distinctive domed world-map dial rendered in blue lacquer with applied rose gold continents. The case measures 43mm in 18K rose gold with a sapphire display caseback revealing the movement. Two independent time zone subdials flank the dial's perimeter, allowing simultaneous tracking of home and destination times without stopping the watch. The central attraction—a flying tourbillon completing one rotation every 30 seconds—bridges classical watchmaking tradition with contemporary design. Water resistance reaches 30 meters, suitable for daily wear rather than diving.

Powered by the automatic Calibre JCAA45, a movement developed in-house, the watch delivers approximately 68 hours of power reserve. The JCAA45's construction prioritizes the tourbillon's visual prominence, positioning the balance wheel and regulating organ at the dial center. This movement represents Jacob & Co.'s commitment to in-house manufacturing standards comparable to traditional Swiss manufacture. The The World Is Yours collection remains limited in production, with each piece numbered and serialized.

Zverev's choice reflects growing affinity among elite athletes for independent watchmakers offering bespoke complications beyond mainstream sports watches. Jacob & Co. timepieces have gained traction among high-net-worth collectors seeking alternative status symbols to conventional luxury brands. The pairing of The World Is Yours—symbolizing global ambition—with Zverev's achievement of world No. 1 status creates deliberate narrative alignment between the wearer's accomplishment and the watch's philosophy.

Retail pricing for The World Is Yours Dual Time Zone Tourbillon starts at $280,000 USD. Grey-market availability remains extremely limited; secondary market transactions typically command prices between $320,000 and $380,000 depending on condition and provenance. Jacob & Co. maintains a selective clientele approach, prioritizing direct relationships with established collectors over traditional authorized dealer networks. Waitlist periods for new references often extend 18–24 months.
