Breitling Watch Premier Heritage Datora. AB2510201K1P1 The historic Breitling Datora was one of the few timepieces launched as part of the luxury watch brand’s original Premier collection back in 1940. Characterised by its vast range of complications, including day and date windows, moonphase apertures and chronograph function, the Datora became a highly desirable watch and due to its short production period, it still remains highly coveted to this day. As part of their 2021 watch releases, Breitling have revived the legendary model as part of their new Premier Heritage collection. The new Breitling Premier Heritage Datora brings to life an exceptional range of complications all within a compact 42mm stainless steel case. Powered by the Breitling Manufacture Calibre B25, the Breitling Premier Datora watch delivers standard chronograph complication with a central chronograph seconds hand and a 30 minutes counter and full calendar function with a double window display for day and month at 12 o’clock and a subsidiary dial at 6 o’clock which points to the date at its circumference and presents a colourful moonphase aperture at the centre. Like all Breitling watches, the movement is COSC certified with an accuracy of -4 to +6 seconds per day and the Calibre B25 ensures a power reserve of 48 hours and is displayed through the exhibition case back. The elegant stainless steel construction also includes an unadorned fixed bezel, cambered sapphire crystal glass with anti-reflective treatment on both sides and non-screw locked crowns with two gaskets to deliver a 100 metre water resistant rating. At the centre, a unique copper-coloured dial delivers all the iconic Breitling Datora functions accompanied by Superluminova coated hands and indexes. To complete its refined aesthetic, the Premier Heritage Datora is fitted with a dark brown alligator leather strap and a matching stainless steel folding buckle.
