The Bentley B05 Unitime worldtime chronograph is back on the road in a new all-black livery. The 500-piece limited series is a continuation of the long-standing partnership between Bentley and Breitling that has produced a string of watches and the placement of the Breitling clock on the dashboard of Bentley’s automobiles.
The Bentley B05 Unitime is a relative newcomer to the Breitling for Bentley lineup. It was launched a couple of years ago to add a GMT offering for world travelers. The watch initially launched in steel and red gold versions, which remain in the collection. Joining these two cases is a new steel case that has been treated with a DLC finish to give it a satin black finish. All of the B05 Unitimes measure 49mm across.
Called the B05 Unitime Midnight Carbon, the new piece includes a black dial with a raised globe motif and a brand-new strap combining a rubber core and a matt crocodile leather exterior.
THe movement, which Breitling has two patents on, includes hours, minutes, seconds, a chronograph function and a 24-city desk including a day/night indicator. The 24 city disk has indications of daylight savings time (DST) and white and black segments for day and night indication.
When switching time zones, the watch’s operator turns the crown forwards or backwards to correct the watch in one hour increments. The movement is a in-house automatic movement from Breitling that is chronometer-certified by the COSC (Swiss Official Chronometer Testing Institute). The winding rotor of the automatic movement evokes the Bentley’s rim in shape and in color, echoes the treatment that has been applied to the Midnight Carbon’s case.
