The Breitling Exospace B55 Yachting is a large, feature-heavy titanium chronograph built around sailing and aviation timing functions. Reference EB5512221B1S1 pairs a 46 mm case and 100 m water resistance with a thermocompensated SuperQuartz movement, analog hands, and a backlit digital display. Its appeal depends on whether you want those specialized functions and can accommodate its size; the listed specifications alone do not establish real-world accuracy, comfort, or sailing performance.
What the Exospace B55 Yachting offers
Breitling identifies EB5512221B1S1 as the Professional Exospace B55 Yachting. The manufacturer’s official product page describes a smartphone-enhanced chronograph and lists an array of digital timing functions alongside conventional analog timekeeping.

How its timing functions fit the name
Regatta and sailing timing
The regatta functions are the clearest reason to choose this version over a conventional chronograph. Breitling says the watch can memorize departure and arrival times, and lists regatta timing and countdown/countup functions. These are useful categories of capability for race timing, but the specification does not demonstrate how easy the controls are to operate on the water or validate the watch in sailing conditions.
Aviation and general chronograph functions
Breitling also describes functions tailored to pilots, including chrono flight, along with a lap timer, electronic tachymeter, flyback, and chronograph. The stated 1/100-second resolution and 99:59:59 maximum are display and range specifications, not evidence that measurements are accurate to that precision in practice.

Analog and digital information
The B55 combines analog hands with a 12/24-hour LCD and white backlighting. That hybrid setup allows conventional time reading alongside digital timing and calendar functions. Whether the display and controls suit your preferences is best assessed in person; no hands-on readability or usability evaluation is available here.
Size, materials, and wearing considerations
At 46 mm across and 15.25 mm thick, the titanium case is substantial. Titanium is the listed case material, but it does not make the watch small: check how the case sits on your wrist and whether it clears a shirt cuff before buying. The 24 mm lug width narrows to 20 mm at the buckle, so those dimensions describe the supplied strap’s taper; they do not guarantee that any replacement strap will fit the watch’s attachment system.

Does this reference have a blue dial?
The official listing for EB5512221B1S1 specifies a blue rubber strap; its listed display is analog and LCD, but the cited product details do not establish a blue dial. Do not infer dial color from the strap or from another Exospace B55 variant. Check product images and the exact reference with the seller if dial color is essential.
Is the Exospace B55 Yachting worth buying?
It is most compelling for someone who specifically wants a multifunction electronic chronograph with regatta and aviation-oriented timing, a titanium case, and both analog and digital displays. It is less straightforward to recommend if you want a compact watch, a conventional mechanical chronograph, or verified current smartphone integration. No current price or market availability is established here, so value depends on the actual price and condition of the exact reference you find.

Smartphone connection and support
Breitling markets the B55 as smartphone-enhanced, and its product narrative says the smartphone is used to enhance the watch’s functionality. That description does not establish current app compatibility, operating-system requirements, or continued connected-service support. The official Exospace B55 user manual is available, but its version date and present-day app status are not established. Confirm compatibility and service availability with Breitling before treating connectivity as a purchase benefit.
Where it sits in Breitling’s Professional collection
Breitling categorizes this specific Exospace B55 Yachting as Professional and says its functions are tailored to pilots and yachtsmen. On that evidence, it is reasonable to describe EB5512221B1S1 as a Professional-collection watch with aviation- and regatta-oriented timing. This model’s listing does not by itself establish the full history or current range of the wider Professional collection.
