The Hanhart Preventor HD12 36mm Black Forest Green MAD Watch Collector Edition lands in the sweet spot where compact sizing and a distinctive colour story can do a lot of the talking.
At 36mm, it speaks to collectors who prefer proportion over presence, while the Black Forest Green treatment gives the Preventor HD12 a more characterful identity than a standard black or silver dial watch.
It’s a focused release for people who notice the small decisions, not just the logo on the dial.

At a glance
- Hanhart has created a Preventor HD12 in a 36mm Black Forest Green MAD Watch Collector Edition.
- The compact case size and dark green character are the defining design points of the edition.
- It’s aimed at collectors drawn to restrained proportions and special-edition watchmaking.
A 36mm Preventor with collector-friendly proportions
The most immediate detail is the size.
A 36mm case gives the Preventor HD12 a more traditional wrist presence than many contemporary sports and everyday watches, which is likely to be part of its appeal.
Smaller watches have moved back into serious collector conversation because they tend to wear with less effort and more nuance.

Here, the dimension suggests a watch designed to sit quietly on the wrist rather than dominate it.
Black Forest Green sets the tone
The Black Forest Green name does more than describe a colour.
It gives the watch an atmospheric identity, leaning into a darker, more grounded shade of green rather than a bright or seasonal tone.

Green has become a familiar modern watch colour, but its success depends heavily on restraint.
On a 36mm watch, a deeper green can feel considered rather than showy, especially when the broader design is kept compact.
The MAD Watch Collector Edition angle
The MAD Watch Collector Edition designation gives this Preventor HD12 a sharper audience than a standard catalogue variant.

Collector editions tend to work best when the changes are specific, wearable and easy to understand, and the confirmed formula here is clean enough to make sense at a glance.
It isn’t trying to reinvent the model through complexity.
Instead, the appeal rests on scale, colour and the added interest of a dedicated collector edition.
