Product Details

Hanhart introduced their first single button chronograph in 1938 which was then known as Calibre 40.

A single button chronograph provides ease of use in that one pusher is used to start, stop and reset the chronograph.

Even today Hanhart continues to produce in-house the movement modifications necessary to incorporate the single button function by using an erosion machine to modify the cam.




With so many watch brands producing chronograph watches, it's refreshing to see Hanhart taking the lead with the single button complication in much of their collection.

Besides ease of use, this design attracts a great deal of interest as a conversation point since the functions differ from a standard chronograph.

The distinctive red pusher is a Hanhart trademark and dates back to early Hanhart pilot's watch designs.

This bi-compax chronograph features a 30 minute register at 3 and small seconds at 9.  The case is in stainless steel and is fitted with a fluted bi-directional rotating bezel with red indicator. 


Other features include:

  • Convex sapphire crystal with interior AR coating
  • Screw down case back
  • Large crown with deep beveled edge
  • Matte black dial with SuperLuminova on numerals and hands
  • Power reserve of 42 hours

This watch is water resistant to 100 meters and is fitted with a vintage black riveted calf skin strap with tang buckle.

Nice watch

"Nice watch"

Verified Owner Comments: This watch face is very legible The case is well finished reminds me of Ickler quality finish. Looks large on wrist due to the large dial surface.

Fits and wears well on the wrist and you gotta love the red button. Movement pushers smooth and the watch keeps good time. The case, the strap all ties together for a real good looking tool watch.

A most excellent watch. Oh ...dealer service OK too.

A great retro chronograph

"A great retro chronograph"

Verified Owner Comments: The Hanhart Pioneer Mk.1 is a superb watch. It really takes the classic design of the WW2- era Luftwaffe "Fliegerchronograph" and gives it a slight modernization that keeps it contemporary yet true to it's vintage roots. This is a watch that can be worn for many occasions, as it has some classic design touches that elevate past a simple tool watch. The case and dial have an excellent level of finish and detailing on par with much more expensive watches. The brushing is well done and the knurled bezel with red reference marker is smooth and firm. The watch could be bit slimmer, but it matches the original Caliber 40 of 1938 predecessor. Small details like the slight downward curvature towards the dial of the second and minute hands to minimize parallax are great touches, and the red accents really pop. The modified Valjoux 7753 movement's monopusher works smoothly and reliably, and the watch runs very accurately. The dial on the whole is very legibly designed.
