Product Details
HDS Pro
This is an amazing watch whose technology requires a bit of explanation.

These watches are the first to feature cases made from HDSPro® stainless steel, which is 100 more times more scratch resistant than standard stainless steel.

While visiting Hanhart in Germany, we were invited to take a sharp object and try to scratch the case - we tried and failed to leave a mark.



Hanhart was closely associated with motor racing in the 1960's and 1970's and the Hanhart Racemaster Series pays tribute to this heritage.

The Hanhart Racemaster GTM features a striking dial with high legibility.

This watch incorporates a number of unusual movement and design modifications.

With a case size of 45 mm, Hanhart has made the following modifications:

  • The registers have been relocated to the edge of the dial for correct spacing using modifications from La Joux-Perret
  • The register at 9 displays continuous sweep seconds
  • Asymmetrical chronograph pushers for ease of use
  • Single button chronograph modification made by Hanhart


Other features include:


  • Convex sapphire crystal with AR coating on both sides
  • Screw down case back
  • Black/blue dial with SuperLuminova on numerals and hands
  • Power reserve of 42 hours
  • Skeletonized Hanhart rotor
  • Tachymeter scale

This watch is water resistant to 100 meters and is fitted with a calfskin strap in racing colors and design.

The single button chronograph modifications are produced in-house by Hanhart using an erosion machine to modify the contour of the cam.
