The Bathyscaphe Chronographe Flyback goes green 

 
 After interpretations in black, meteor grey and blue, the Fifty Fathoms Bathyscaphe Chronographe Flyback model is going green. This new natural-coloured timepiece is the ideal ally for any situation, whether underwater, on land or in the air. 

 The Fifty Fathoms Bathyscaphe diver's watch is one of Blancpain's must-haves. It owes its aura to its remarkable performance and robustness, as well as to its unique style, which has evolved over the years while respecting the collection’s DNA. The Bathyscaphe now appears in a new chronograph version adorned in green from dial to bezel; a shade enhanced by peerless expertise and skills in terms of dial-making. 

Dozens of steps are required to achieve a perfect colour and finish, not to mention the considerable research and development involved in finding the ideal shade. Once the initial phases devoted to the shape and apertures have been completed, the dial is polished in two stages: the first to remove scratches; and the second to obtain a soft, smooth appearance. This is followed by a series of processes designed to give the surface a special texture, including a sunburst effect that endows the dial with a pattern of lines radiating from the centre. The chronograph counters are then hollowed out and snailed to create greater overall depth. The highly technical colouring process can now begin. The dial is coated with several nanometric layers of material. Transformed by the surface, rays of light reflect the desired hue. The dial of the Fifty Fathoms Bathyscaphe Chronographe Flyback can then reveal its subtle shades of green which change according to the angle of illumination, sometimes taking on metallic shades. 

Colours, surfaces and textures do justice to the heart of this timepiece, the Manufacture F385 calibre, visible through a sapphire crystal caseback. The self-winding chronograph movement beats at a frequency of 5 Hz, enabling each second to be divided into 1/10th intervals. This high frequency guarantees increased accuracy, particularly when timing events. The F385 movement is equipped with a vertical clutch and a chronograph mechanism controlled by a column-wheel. It has a flyback function that enables the chronograph to be reset to zero and restarted instantaneously by simply pressing the push-piece located at 4 o'clock. 

The new Fifty Fathoms Bathyscaphe Chronograph Flyback comes in a 43.6 mm satin-brushed black ceramic case topped by a rotating bezel featuring a green ceramic insert. It is paired with a NATO or sail canvas strap.
