Product Details

Green Dial and Brand New 36 mm Case

The Hanhart Preventor HD12 series, featuring Hanhart's newly developed hardened HD12 steel, has quickly become one of the best selling watches in the company's long history.

Demand has consistently outpaced available supply due to its unique combination of historical design, robust build quality, wearability, and attainability.  

We are pleased to announce that Hanhart is now offering the Preventor HD12 in a compact but versatile 36 mm case size (the standard model HD12 watches are 39 mm), starting with this 200 piece limited edition featuring a deep green dial inspired by the Black Forest region of Germany (Hanhart's home).


Hanhart X The MAD Watch Collector

Hanhart designed this new watch in partnership with Russell, the MAD Watch Collector, a watch enthusiast who has grown his well known Youtube channel around his passion for watch collecting. 

When they met in the Black Forest, Russell proposed to Hanhart the idea of expanding the reach of the already popular Preventor HD12 Collection by reducing the size of the case.  

The limited edition number is engraved into the solid steel case back of each piece along with "MAD PREVENTOR."  This model is limited to a total of 200 pieces.


A Nod to the Past

Hanhart is a German watch company that doesn't need to create an "artificial past" for marketing purposes - the company has been continuously producing watches since 1882.

This new watch incorporates elements from historic Hanhart models, including cathedral hands that are curved at the ends to avoid parallax errors.

The seconds hand features a distinctive red tip to enhance legibility, while the dial is clean with no date window (and no ghost date wheel or crown position).

Hanhart has also incorporated their historical logo on the dial, crown, and case back.


Hanhart HD12 Hardened Steel

The hardened case of this watch is created from Hanhart's hardened HD(hardened)12(1200 Vickers) steel.  HD12 steel achieves an outstanding level of surface hardness and scratch resistance while still maintaining the corrosion resistant properties typical of stainless steel. 

Hanhart HD12 Steel
The process of creating HD12 steel begins with the diffusion of carbon into the stainless steel, creating a gradual transition from a hard surface to a softer core which helps prevent brittleness.

Next, a transparent finish is then applied via a physical vapor deposition process for additional protection, bringing the total surface hardness to 1,200 HV.  At only 200 - 300 HV, conventional 316L stainless steel watch cases are no match for HD12 steel.



Important features include:
  • Black Forest Green dial
  • New 36 mm case size
  • Limited edition of 200 pieces
  • HD12 hardened steel case
  • Water resistant to 150 meters
