Hublot adds two models to the Big Bang Ferrari line-up, the result of a partnership between the Swiss watchmaker and the Italian maker of supercars, including the Big Bang Ferrari Grey Ceramic, a tribute to the Ferrari NART.

Soon to be unveiled at Baselworld 2015, the Hublot Big Bang Ferrari Black Ceramic is styled in black and red, the classic colours of Ferrari. And the second model is the Big Bang Ferrari Grey Ceramic, modelled on the colours of Ferrari NART (short for “North America Racing Team”), the American-backed team active in the sixties and seventies that competed in endurance races, winning at Le Mans and Daytona. Both the new Big Bang Ferrari models are in 45 mm in diameter, with cases in ceramic with black composite inserts. A black mesh inspired by Ferrari grilles, the dials have a Ferrari prancing horse inset at nine o’clock. And the minute register at three o’clock integrates the date window with a skeletonised date numeral against a bright yellow backing.

Schedoni leather-covered rubber straps – the Italian firm is the maker of Ferrari leather goods – are standard, and are easily interchangeable by pressing the button on the lug. To complete the automotive aesthetic, the straps are painted with a racing stripe. And Inside is the HUB 1241 Unico movement, Hublot’s modular, in-house chronograph calibre with a flyback function, fitted with a rotor inspired by a hubcap. Each model is limited to 250 pieces, with pricing to be revealed at Basel next month.

Breitling’s new in-house movement is the calibre B14, a hand-wind, mono-pusher chronograph found inside the Transocean Chronograph 1915 limited edition.

Breitling made major contributions to the development of the wrist chronograph, including inventing the modern two-button chronograph as we know it in 1934. At Baselworld 2015 Breitling will unveil the Transocean Chronograph 1915, a single-button chronograph equipped with the B14 movement. The B14 movement is the manual wind version of Breitling’s Calibre 01, the brand’s first in-house movement. It features a column wheel and vertical clutch, but most notably a single pusher for the start, stop and reset functions of the chronograph. 

The one button set up is a nod to Gaston Breitling’s (the eponymous founder’s son) invention of the single-pusher chronograph in 1915. Thus the Transocean Chronograph 1915 marks the centenary of Breitling’s invention, and naturally is limited to 1915 pieces. 

The dial is an ivory shade with an appropriately vintage appearance, encompassing the faux aged Super-Luminova and the retro-style dial text. And the date window, despite the admirable vintage font used for the date, remains incongruous with the dial, as is almost always the case this vintage remakes.

The watch has a 43 mm steel case and is available on a crocodile leather strap, priced at 13,010 Singapore dollars or 8400 Swiss francs. It’s also available on the Ocean Classic mesh bracelet for 13,170 Singapore dollars or 8630 Swiss francs.
