Understanding how to repair keyless works on a NH35 movement is crucial for watchmakers and enthusiasts alike. This process requires precision and a thorough understanding of the mechanism. Successfully repairing these intricate components restores functionality and extends the lifespan of the timepiece. The keyless works, responsible for winding and setting the watch, are delicate and prone to damage. Therefore, careful attention to detail is paramount throughout the repair process. This article will provide a comprehensive guide, outlining the necessary steps and precautions.
The NH35 movement, known for its robust construction and relatively simple design, still contains delicate components within its keyless works. These components, including the winding stem, crown, and various gears, work in concert to translate the rotational force from the crown into the mainsprings winding action and the setting of the hands. Malfunction in this system can manifest as a crown that won’t pull out, a crown that slips, or an inability to set the time accurately. Precise diagnosis of the problem is the first step in successful repair.
Disassembly requires specialized tools and a steady hand. Improper handling can lead to irreversible damage to the delicate parts. Each component must be carefully removed, noted, and stored to prevent accidental misplacement or damage. The use of a watchmaker’s loupe is recommended for inspecting and identifying small components and signs of wear or breakage.
Once the keyless works are disassembled, individual components can be inspected for damage such as wear, breakage, or bending. Cleaning the components using appropriate watchmaking solvents is essential to remove accumulated dirt and debris which can impede proper function. Lubrication with appropriate watch oils is crucial to ensure smooth operation and longevity of the repaired mechanism.
Reassembly requires meticulous attention to detail, following the reverse order of disassembly. Proper alignment of gears and levers is critical. Improper reassembly can result in functionality issues or further damage. Thorough testing after reassembly is crucial to confirm proper functionality and accurate timekeeping before reintegrating the keyless works back into the watch movement.
