Breitling Premier Heritage B25 Datora 42 Watch Review

Breitling Premier Heritage B25 Datora 42 Watch Review

The third and final instalment of the recently released Breitling Premier Heritage watch collection is the B25 Datora 42, an elegant dress piece filled with a remarkable range of complications and an aesthetic worthy of a vintage calendar watch.

It’s been a big year for Breitling. They’ve already impressed with a new Chronomat South Sea Ladies collection, a new limited edition Red Arrows watch as part of their Chronomat series and more recently, a new Avenger GMT Night Mission. Then this week, in line with the Watches and Wonders 2021 event, the Swiss watch manufacturer launched an entirely new generation of Breitling Premier watches named the “Premier Heritage” which they describe as taking inspiration from the inventive spirit of Breitling’s founders Leon Breitling, his son Gaston and his grandson Willy and their contributions towards the development of the chronograph. Part of the collection is a duo of Breitling Premier Heritage B25 Datora 42 watches delivering highly visible and complex functions including a day and month window and moonphase display.

History of the Breitling Datora

Watch connoisseurs well-versed in the Breitling brand will already know of their long established history with the chronograph complication. During the 1940’s, Breitling were renowned for supplying aviation instruments to the British Royal Air Force and other air forces around the world through its HUIT Aviation department. Many of these robust and powerful designs incorporated a chronograph function for precise timekeeping in the skies and on land. Willy Breitling, who led the charge at the time, realised however that while military personnel fighting the war might require a durable utilitarian instrument, regular citizens yearned for something more sophisticated. This is when the Breitling Premier watch collection was launched in 1943.

Designed for discerning and stylish ladies and gentlemen, the Breitling Premier watch collection became home to a stunning range of designs including a split-seconds chronograph, or Rattrapante, a classic chronograph and a model named the Breitling Datora. 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 was produced for only a short period of time between 1947 and 1951. Due to this short production period, Breitling Datora watches remain highly coveted and when they do rarely appear on auction sites, it’s not long before they’re snapped up and for a hefty price tag at that. Now the popular design is delivered as part of a permanent collection. Let’s take a look at the new Breitling Premier Heritage B25 Datora 42.

The Breitling Premier Heritage B25 Datora 42

Inspired by their 1940’s counterparts, the new Breitling Premier Heritage B25 Datora 42 watches contain a lot of information in a compact 42mm case. In addition to standard chronograph complication with a central chronograph seconds hand and a 30 minutes counter, the Breitling Manufacture Calibre B25 delivers 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 not only points to the date at its circumference but presents a colourful moonphase aperture at the centre.

For now, there are two Breitling Premier Heritage B25 Datora 42 watches to choose from. The first comes under reference AB2510201K1P1 and brings a 42mm stainless steel case paired with a unique copper-coloured dial and a dark brown alligator strap. The second reference RB2510371G1P1 is the more opulent and expensive of the two dressed in 18 carat rose gold with a classic silver dial dressed in matching rose gold Arabic numerals and hands and a dark brown alligator leather strap. Each strap is paired with a folding buckle engineered from the same case material.

Both designs follow suit in the rest of their specifications including their unadorned fixed bezels, Superluminova coated hands, cambered sapphire crystal glass with anti-reflective treatment on both sides and non-screw locked crowns with two gaskets which deliver a 100 metre water resistant rating. The Calibre B25 automatic winding movement is also put on display through the exhibition case backs of both Breitling Premier Heritage B25 Datora 42 watches where the Côtes de Genève motif adorns the oscillating rotor and some of the 47 jewels can be seen. The in-house movement also promises a 48 hour power reserve and a frequency of 28,800 vibrations per hour.
