Breitling Montbrillant Datora SS Silver Dial

The Breitling Montbrillant Datora reference A2133012/G746 is a standout within the Navitimer lineage, featuring a polished stainless steel 43 mm case introduced during the model’s production run between approximately 2002 and 2013. Powered by the Breitling Caliber 21 automatic chronometer movement, based on the revered Valjoux 7751, it delivers a 42‑hour power reserve and COSC certification, underscoring its precision and engineering pedigree. Its silver “Mercury” dial presents a sophisticated triple calendar layout with day and month apertures beneath 12 o’clock, a date indicated by a red‑tipped hand encircling the dial, and a 24‑hour/GMT subdial—making it an exceptionally functional yet elegant complication piece. The bidirectional slide‑rule bezel, a hallmark of the Navitimer family, enhances its technical appeal, enabling aviation‑style calculations and reinforcing its heritage as a pilot’s instrument. With a water resistance of 30 meters and a sapphire crystal, it balances everyday wearability with collector desirability. Although not officially designated as a limited edition, this variant’s combination of dial, complications, and movement makes it highly sought after by enthusiasts of vintage‑inspired chronographs. Its robust technical specification and historical lineage position it as a refined choice for collectors who value both form and function. Like New with Breitling box and papers dated 2007.
