Hendrik Lorentz “speed of light”

Slide 1


The black version of the Lorentz is conceived in the year of the speed of light, 2015. This is the year in which Einsteins “spooky action at a distance” of light turned to be true. And therefore only light travels way faster then light! Also the combination of white hands on a black dial really looks cool!

For an indepth explanation on these bold statements and the role of our Dutch friends in Delft (for which they may just get a Nobel prize) you can read their paper in Nature.

This watch stays dedicated to Hendrik Lorentz, the scientific father of Albert Einstein. The design is inspired by the way of thinking of Theoretical physicist Hendrik Lorentz and his “local time” formulas. In this design his “local time” is found in the scales which is a separate one for each hand. Additionally the dial is galvanised black, with high gloss white hands. By this combination readability is superb. Also it gives a noble and plain look to the watch.


The engine of this watch is the automatic Swiss Soprod A10-2 movement which can be seen through the sapphire display back. The movement is exquisite in its finish. The movement is dynamically balanced by Pellikan timing in 6 positions increasing its accuracy even further. The accuracy falls within the demands for chronometric qualification.

The core technology of almost any mechanical movement consists of the balance and hairspring. Invented by Christiaan Huygens (and John Hooke) around 1670.
