This rare Hahn quarter repeater chronograph is one of the most complicated production watches of its time. Servicing a watch of this age and complexity is an undertaking only few will attempt due to the enormity of potential complexity and unknowns. Owning one fully serviced is a rare opportunity.
Hahn was founded in 1873 and would later become famous for their work with Breitling and the evolution of chronograph design. According to our research, Hahn had its main factory in Landeron, Switzerland. Their trademark, Hahn Landeron Depose, incorporated this location on their earliest work. It wasn't until much later, in the 1920's, that Hahn would identify their chronograph movements by the Landeron trademark and remove reference to Hahn.
Today, repeater chronograph watches are very expensive and when this watch was manufactured, it was likewise costly to own one. This watch features a beautiful engraved case that is a combination of 18K gold filled (mid-case) and plated (front/back.) The back of the case shows a horse and its owner engaged in an equestrian event. It was not uncommon for these engravings to reflect the life and interests of its owner. Properly servicing this watch requires you to go back in-time, not only into the minds of the manufacturer and the methods available to them at the time, but also to all of the watchmakers who worked to keep the watch functioning over so many years. Over a year ago I began working on this watch. I put it down after having succeeded at various steps. Recently I resumed my work which is now completed. The result is quite pleasing in all respects. In consideration of its age and manufacture, its performance is now excellent and capable of guiding its new owner through the day with good accuracy and reliability. Performance numbers are provided below. The watch is 56.6mm in diameter excluding the crown and has a thickness of 20mm.
The pocket watch is wound from the crown. You do not pull the crown as you would on a standard watch to set the time. Instead there is an exposed lever at about 4 o’clock on the dial side of the watch that you slide upwards towards 12 o’clock when you wish to set the time and downwards when done setting. When in the downwards position you can wind the watch. The back of the watch (movement side) is hinged. The front (dial side) bezel is friction fit and does not need to be removed to set the time.
Averages described below are across all 6 measured watch positions. See the Support page of this website for more information to understand performance numbers and for expectations. After a full wind of the mainspring, the watch has an average rate across all positions of +10 seconds, an average beat error of 0.9, and average amplitude of 261. However, as a vintage pocket watch, rate will vary considerably by position. You would want to be satisfied with the watch maintaining time within approximately 1 minute every 24 hours for this watch based on your handling and storage patterns. If using the chronograph more than 12 hours after you have fully wound the watch, it's a best practice to give the watch a full wind.
