Pre-owned Breitling Transocean ref A1931012/BB68 (2012) is one of the more technically interesting watches to wear the Breitling name. Introduced as part of the Transocean collection, it draws inspiration from the brand’s elegant mid-century watches while incorporating a complication rarely seen in Breitling’s modern catalog. The “1461” in the name refers to the number of days in a four-year leap-year cycle, an homage to the watch’s complete calendar mechanism that only requires correction once every leap year. That’s a remarkable level of convenience for a calendar watch and one of the reasons this reference has developed a following among collectors. The black dial packs an impressive amount of information into a clean, balanced layout, displaying the day, date, month, moonphase, and chronograph functions without feeling cluttered. At 43mm, the polished stainless steel case has modern proportions while maintaining the refined aesthetic that defines the Transocean family. Shop Breitling Transocean Collection
