Housed in a 46mm brushed finished titanium case, the Exospace B55 presents its "Volcano" black dial with a partially skeletonized hour hand, luminous filled hands, and applied polished large Arabic numerals at 3, 6, and 9 o'clock. The remaining hour positions are marked with small luminous painted Arabic numerals, while 1/100th-second graduations ring the outer dial. A sapphire crystal glare-proofed on both sides protects the display, and the crown features two gaskets alongside an integrated pushpiece. Water resistance is rated to 100m/330ft.
The B55's quartz movement drives an impressive range of complications: a digital perpetual calendar, a chronograph and stopwatch precise to 1/100th of a second with a maximum duration of 99:59:59 hours, a flyback chrono function, an electronic tachymeter, seven daily alarms, GMT/second time-zone display, and selectable 12- or 24-hour digital time readout. Additional pilot-oriented features include mission elapsed time with countdown and count-up, a take-off/landing and flight time log, a battery end-of-life indicator, and high-intensity LCD backlighting with an automatic switch-on when the watch is tilted to a 35° angle. The brushed bi-directional turning bezel carries a compass scale.
The watch is presented on a brushed titanium Professional III bracelet secured by a folding clasp with safety latch. Smartphone pairing via Bluetooth Low Energy enables data transfer and remote adjustment of time, date, and UTC settings, as well as phone call notifications on the watch. Reference EB5510H11B1E1 is accompanied by its original Breitling box and Breitling papers.
