In the ever-evolving world of luxury watchmaking, few creations struggle to balance advanced mechanical complexity and refined aesthetic appeal. One such exemplar is the Breitling Transocean Chronograph Unitime 46mm, reference RB0510U0A733CS, a timepiece that caters not only to connoisseurs of horology but also to global professionals who demand both form and function from their wristwear.
Encased in a stately 46mm rose gold-tone stainless steel housing, this watch exemplifies Breitling’s pursuit of innovation through its in-house Caliber B05 movement. Designed to merge chronograph performance with seamless world-time functionality, the Transocean Unitime embodies mechanical ingenuity and cosmopolitan sophistication.
World-Class Design Meets Global Function
At a glance, the Transocean Chronograph Unitime is captivating. But beyond its elegant façade lies a true traveler’s tool—a watch engineered for those who live across borders and time zones. Featuring a dual-disk world time system, this timepiece allows the wearer to track the local time simultaneously and the time in 24 major cities around the globe, all displayed on a tastefully organized dial that features a stylized globe at its center.
Thanks to its user-centric engineering, reading and adjusting world time has never been easier. The city ring on the outermost edge works in tandem with a 24-hour rotating disk, enabling the wearer to see at a glance what time it is in Tokyo, London, Sydney, or any other key global city. There is no need to calculate time differences or consult your smartphone mentally—Breitling Transocean Unitime does the math for you and does so in style.
Effortless and Intelligent Time Zone Adjustments
What sets the Unitime apart from traditional world timers is the simplicity and intuitiveness of its time zone adjustment system. Many world-time watches require tedious manual corrections of multiple components or a temporary timekeeping stop. Breitling Transocean Unitime, powered by the Caliber B05, eliminates this friction.
When traveling, all you need to do is:
- Pull out the crown to the first position,
- Turn it forward or backward to align your destination city at the noon position,
- Watch as the hour hand, city disk, and 24-hour disk move in perfect harmony,
- Observe the date window update automatically, matching the new local time without disrupting the chronograph or main timekeeping functions.
This instantaneous, synchronized adjustment is made possible by an internal gear and clutch mechanism unique to the B05 caliber, allowing time zone transitions with zero loss of precision—a rare achievement in mechanical watchmaking.
The Engine Within: Breitling Caliber B05
The Breitling Caliber B05 is a powerhouse automatic chronograph movement developed in-house based on the highly respected B01 platform. What makes the B05 unique is its integration of a patented world time module, designed to deliver world-class functionality without compromising durability, power reserve, or chronometric accuracy.
Key Technical Specifications:
