Hanhart Pioneer Racemaster GTM Automatic Chronograph German

Hanhart Pioneer Racemaster GTM Chronograph

Unveiled on October 2012, the Hanhart Pioneer Racemaster GTM (ref. 737.670-0010) automatic chronograph is based on their older Hanhart Pioneer MonoScope self-winding chrono that was presented back in January 2012. Powered by the same movement and coming in the same stainless steel case, the Racemaster GTM features a different bezel and sports a color scheme that just screams ‘1970s’!

Although chronographs of that time were not particularly large, this beast comes in an oversized body 45 millimeters in diameter and whole 16 millimeters thick.

According to the German brand, the body is crafted from their patented “HDSPro” stainless steel alloy, which is claimed to be 100 times more scratch-resistant than the alloys usually employed by watchmaking industry.

Beating inside this case is the same Caliber HAN4212 automatic movement that powers the aforementioned Monoscope. Outsourced from a third-party manufacturer (some sources claim that the mechanism is based on the good old ETA Valjoux 7750 chronograph movement; I wasn’t able to find information from an official source that would unequivocally confirm it) the caliber sports a set of modifications that not only convert it into a monopusher (which basically means that you can operate all functions of the chronograph using only one push-piece to cycle from “start” through “stop” to “reset” and back to “start”), but also increase the spacing between the setting crown and the push-piece thus making it more comfortable to operate.

Of course, as you can see on the pictures, they lost the usual 12-hour chronograph counter in the process making it more readable and also a lot cooler (at least, in the humble opinion of yours truly.)

Another nice thing about this movement is, of course, the skeletonized oscillating weight that features the brand’s logo.

Being inspired by racing cars of the ’60s and ’70s, the face of the Racemaster GTM features three main colors with the main portion of the dial painted black, the hands red and the chapter ring blue. The silver-toned chronograph and subsidiary seconds sub-dials are nicely matched by light-grey Superluminova on the hands and applied hour markers and strongly remind of German sports cars of the pre-WWII period with their signature unpainted, silver-colored bodies.

It is also nice to note that the red color of the hands is repeated not only on the single chronograph pusher but also on the inner side of the perforated leather strap making the watch look especially handsome.

The price still remains unknown, but different online shops sell the Monoscope for some $7000, so the Racemaster GTM must be close to it*.
