A new
era
Four years in the making, now part of our lineup—the new Caliber B31 marks a major milestone in Breitling’s evolution: our first exclusive manufacture time-and-date movement. Drawing on the mechanical legacy of the Breitling Manufactur Caliber 01—an industry benchmark since 2009—it carries Breitling’s craftsmanship story forward.

Compact at 28 mm × 4.8 mm form, the Caliber B31 features Breitling’s signature components: a free-sprung balance wheel for enhanced precision and a skeletonized oscillating weight that powers the automatic movement. Visible through the open caseback, these details are finished with Geneva stripes and perlage—built to be seen.
