Bernard Richard Manufacturer (BRM) has launched the lightest automatic chronograph in the world.
The MK-44 timepiece uses titanium, fortal HR, makrolon and inox 316, which has resulted in a new weight record of 48.80 grams. The watch took two years to create.
The case is created in makrolon, the extra-light material used for the side windows in the most race cars. The back is made of fortal HR, an extra-light aluminium alloy that is employed in motorsports.
To reduce the weight even further, titanium fastenings have been made hollow, while the sapphire glass has been reduced from 1.5 to 1 millimetre in thickness. The rotor is half the weight of that used in a regular movement.
Much of the dial has been relieved, the hands are thinner and the date has been eliminated for maximum weight savings. The band is made of extra-light fabric and fibre with multiple openings.
