ince its launch in August 2024, the Preventor HD12™ has not only set new standards in terms of robustness and suitability for everyday use but has also established itself as one of the bestsellers in the Hanhart portfolio. The combination of scratch-resistant HD12™ steel, classic Hanhart design and reliable automatic movement struck a chord with the times and enjoyed enormous demand.

Now, together with the specialist magazine Armbanduhren, Hanhart presents an exclusive special edition that is causing a stir with its deep, silky purple dial. The “Silk Purple” combines the technical strength and precision of the Preventor HD12™ with a bold, modern color accent - a timepiece that will delight collectors and watch enthusiasts alike.

The color of the special edition makes the Preventor HD12™ an extravagant and stylish outdoor watch, complementing and yet setting it apart from the solid versions in dark blue and black. The matt background in dark purple provides a perfect contrast to the Arabic numerals printed in white with an overlay of luminescent Super Luminova C1, which shimmers green in the dark. The same luminescent material is also used for the skeletonized hands for hours and minutes, which have their origins in military pocket watches.

Even the filigree second hand, including the counterweight, is coated with luminous material and its red-lacquered tip bends towards the surrounding second hand with a five-part 60 scale to ensure perfect readability by reducing the parallax effect. Limited to a total of 200 pieces, 150 of which will be sold in Germany, the Preventor HD12™ «Silk Purple» is a rare statement on the wrist. Made from hardened HD12™ stainless steel, the watch can withstand the ordeals of everyday life as well as major adventures.

The solid screw-down case of the Preventor HD12™ is water-resistant to 15 bar, making it ideal for everyday use and contact with water. It is made from the newly developed HD12™ steel from Hanhart, in which carbon is diffused into the stainless steel in a multi-stage hardening process. This creates a gradual transition from a tougher core to a hard surface. In addition, the case is given a transparent PVD coating, which makes it even more resistant to scratches. The HD12™ steel achieves a surface hardness of an impressive 1200 HV according to Vickers - more than five times that of conventional 316L stainless steel with around 220 HV. By comparison, the scratch-resistant, convex-curved sapphire crystal of the watch has a hardness of around 2000 HV.

The finely coordinated surface finish combines brushed surfaces on the horns, case flanks and bezel with polished accents, including the historic Hanhart “h” logo on the crown and on the back. With its balanced proportions - 39 millimetres in diameter, 10.5 millimetres high and 46 millimetres long over the lugs - the case impresses with its robustness, elegance and harmonious design.

Inside the Preventor HD12™ is the Sellita caliber SW200-1 or Soprod SOP P024. It controls the hours, minutes and center seconds, whereby the Hanhart version is deliberately designed without a date display and also without a date detent position on the crown. The movement beats at a frequency of 4 Hertz or 28,800 A/h and has a stop-second function when the crown is pulled out, which enables the time to be set precisely. The automatically winding rotor with Hanhart signature ensures a reliable power supply and guarantees a power reserve of up to 38 hours.

The “Silk Purple” is worn on a solid stainless steel bracelet with a 20 millimeter lug and a folding clasp bearing the historic Hanhart logo. To make it particularly resistant to scratches, the steel bracelet also has a transparent PVD coating. Hidden inside the clasp is a practical, fold-out extension in the style of a diver’s watch, which can be used to quickly and easily loosen the strap by around one centimeter. The individual elements of the strap are finished to a high standard and carefully screwed together to ensure stability and durability.

As a pioneer in the development of wristwatch chronographs and stopwatches, Hanhart has played an important role in the history of the German watch industry. Thanks to its passion for technical inventiveness, Hanhart continues to set itself the highest standards and is guided by the following maxims: precision and reliability, perfect readability and simple, safe operation as well as the best possible robustness. Since 1882, the watch manufacturer has been producing timepieces that combine perfection with unmistakable design. The development, production and distribution of the mechanical watches is located in Gütenbach in the Black Forest in Germany.
