Hanhart Pioneer MonoScope Single Button Chronograph Black Dial on Bracelet - Fluted Bezel

This watch is Hanhart's largest Pioneer single button chronograph with a case size of 45 mm.

As in their other larger watches, Hanhart has taken the time to modify the movement to correctly space the chronograph registers to the case size.

These modifications, as well as those to create the single button chronograph function are developed and produced under the supervision of Hanhart's watchmakers by La Joux-Perret.

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 contour of 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.

Another Hanhart movement modification is the increased spacing between the pusher and the crown to improve ease of use.

This bi-compax chronograph features a 30 minute register at 3 and small seconds at 9.  The case is in stainless steel.

• Convex sapphire crystal with interior AR coating
• Screw down case back
