When WatchBuys found out that Hanhart had a batch of NOS Valjoux 23 column wheel chronograph movements on hand, they knew that they needed to do something awesome with them. And so the teams over at WatchBuys and Hanhart got together to create a new model utilizing this important historical caliber. But they didn?t stop there. To make the project really special, they decided to go one step further and add a flyback complication on top of the chronograph?introducing the Hanhart Pioneer Valjoux 23 Flyback.
The case measures 42 millimeters across, 12.5 millimeters thick, and has a lug width of 22 millimeters. The stainless steel case is satinized and coated in gray/gunmental DLC, giving it a cool, tool-watch vibe. There?s a sapphire on both ends of the case, so around back is an aperture showcasing the beautiful caliber numbered x/90 (more on this later). A coin-edge bezel with a red pip frames the dial, and on the right side of the case you have the large crown and pushers with the one at 4 capped in red to indicate the flyback function.
The dial is black with a two-register layout: thirty-minute counter at 3 and sweep seconds at 9. Below 12, Hanhart opted to use the historical Hanhart logo, which looks awesome. The red from the bezel and pusher is carried over to the dial, accenting the hand at 3. Overall, the watch has a great vintage vibe without looking too much like it was yanked right from the archives.
