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
  • Off-white 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 brown riveted calf skin strap with tang buckle.

Great size, great weight, great watch!

"Great size, great weight, great watch!"

Verified Owner Comments: Firstly, the Hanhart MKI was not the watch I had originally intended to purchase. I was looking at the MonoControl with a white face instead. When I called to order, the WatchBuys representative asked me a lot of questions that I hadn’t even considered I.e. what size is my wrist? Have you worn a 42mm watch before? The WatchBuys representative suggested the MKI based on the smaller size and shorter distance lugs because of my wrist size (6 7/8”). After consideration I decided to go with the MKI and am completely happy with it. I absolutely love the aesthetic of this watch! From the eggshell dial to the Arabic numerals, the red pusher and the other contrasting red and black elements - it all comes together very nicely in my opinion. The dark brown strap also picks up on the red elements and really compliments the watch. Could I have gone with the MonoControl? Probably - I don’t know that the 42mm with the extra 3mm distance the lugs would have made it uncomfortable to wear. That said... - more details

i give kudos to Watch Buy as they immediately replaced a watch band that had a malfunction at no cost. Great customer service.

Terrific experience with Watch Buys was the icing on the cake.
