Front of Bentley GMT B04 S Carbon watch

Breitling for Bentley collection launched new models at Baselworld 2016 and one of them is the Bentley GMT B04 S Carbon. It just comes in a 250-piece limited series.

The Bentley GMT B04 S Carbon features a remarkably unique design based on the use of asymmetrical lugs and integrated pushpieces moulding the shape of the case along with an exclusive black rubber strap. With the use of Carbon as material, Breitling is able to give this watch a more sporty-looking exterior that distinguishes it from its predecessor. With red accents, a carbon case and the inclusion of a second time zone along with chronograph function, it makes this a pretty desirable watch. Front of Bentley GMT B04 S Carbon watch
The Bentley GMT B04 S Carbon as its name would suggest, comes in a carbon case measuring at 45 mm in diameter. The case is made using a high-tech case material that comprises of tiny carbon fibres (just 30 microns in diameter) woven into several hundreds of layers placed at a 45-degree angle between each successive layers, and then bonded by heat-set resin. The special material and production method used help to give it a distinctive matt black appearance and higher durability for shock-resistance given the rigidity of carbon materials.

Similar to its casing, the dial is also made of carbon with a visible weave but what gives this watch a look reminiscent to that of sports cars are the red-rimmed counters, resembling racing car instrument panels. There are three counters positioned on watch namely, the seconds counter at the 9 o’clock position, a 12-hour counter at the 6 o’clock position and a 30-minute counter at the 3 o’clock position. Like its predecessor, we also see a date window included on the dial in between the 4 and 5 o’clock position. To give it that rugged look, the watch comes with a knurled bezel similar to the previous model.Side of Bentley GMT B04 S Carbon watch
Whether as a business or travel companion, the dual timezone chronograph provides great user-friendliness. The black hour hand showing the local time can be quickly and easily adjusted by either rotating the crown forwards or backwards, without the loss of any precision in terms of minutes and while ensuring the automatic adjustment of the date in both directions. The red hand on the dial helps to keep track of home time in 24-hour mode and we have to add that the use of a red hand does help with enhancing legibility especially when you have a busy dial to contend with.

The Breitling watch also features a rotating inner bezel containing the names of 24 cities representing different time zones. It serves to show the time at a glance in every timezone compared to the time shown by the 24-hour hand.Bentley GMT B04 S Carbon detail 02
The Bentley GMT B04 S Carbon is powered by the same movement as its predecessors, the Breitling Calibre B04. This mechanical self-winding movement is protected by two patents and is developed and produced entirely in-house by Breitling. It is also chronometer-certified by the COSC (Swiss Official Chronometer Testing Institute), a recognized mark for superior precision and reliability.

The Calibre B04 operates at a high frequency of 28,800 vibrations per hour (4 Hz), powering the hours, minutes, seconds, chronograph and aperture-type date functions. It also comes with a 70-hour power reserve which is pretty impressive.Bentley GMT B04 S Carbon detail
More notably, the Bentley GMT B04 S Carbon model comes with a solid case back and is water-resistant to 100 m. What makes it so different from the titanium version is that instead of a transparent case back, we see a solid case back being used. From an aesthetic viewpoint, it would have been better if Breitling chose to retain a transparent case back thus allowing a clear look at the movement operating.

The Bentley GMT B04 S Carbon offers a refreshed look using carbon as its main material and this is a way of paying homage to Bentley’s competitive feats through the use of advanced materials only found in competitive sports cars. What we really do like about the watch is the sporty and rugged feel it gives with just one glance, the matt black appearance and a carbon dial with red accents certainly adds to the aesthetics of it.
