Breitling has unveiled the Chronoliner B04, a blue boutique edition of a model that it first released in 2015 but is now updated with an in-house COSC-certified chronograph movement. This is a limited edition timepiece only available at Breitling boutiques around the world.

The boutique edition has an all-blue color scheme

Best known for their aviation-themed watches, the Chronoliner was launched in 2015 and was inspired by the pilot’s chronographs it made in the Fifties and Sixties. The Chronoliner B04's large 46 mm case in brushed stainless uses a blue dial with silver counters and a blue ceramic bezel. The matching rubber Aero Classic strap is embossed with a pattern reminiscent of the steel mesh bracelets equipping the brand’s instruments during the Fifties and Sixties.

The ceramic bezel has a 24 hour marking for the GMT function which is indicated by a red-tipped needle on the dial. When introduced in 2015, the Chronoliner was the first Breitling model to use a ceramic bezel, now a staple of luxury watch bezels. The bezel has a star-shaped cut-out that facilitates handling even with gloves.

Inspired by chronographs made in the Fifties and Sixties

The big change in the boutique edition is the presence of a new movement. Initially powered by Breitling’s Caliber B24 movement based on the Valjoux 7754, the Chronoliner B04 however uses the in-house Manufacture Caliber B04. Entirely developed and produced in the brand workshops, this ‘engine’ officially chronometer-certified by the COSC is distinguished by its extremely functional dual timezone system.

To adjust the main hours hand to local time, all the wearer need do is pull out the crown and turn it either way in one-hour increments, without losing any precision in terms of minutes and while ensuring automatic adjustment of the date in both directions.

The watch has a special engraved caseback – sporting a vintage-look pin-up and “Special delivery” inscription. The Chronoliner B04 issued in a 100-piece limited edition, is available only from one of the 50 or so Breitling boutiques around the world. Breitling was recently sold to private equity firm CVC Capital Partners for $870 million (€800 m). The transaction will be completed in June, subject to approval from competition authorities.
