Fine-Tuning My Watch Movement: A Day of Progress
Just spent the day fine-tuning my watch movement with a little help from ChatGPT 🤖. Nailed the balance wheel and hairspring combo for my 36,000 vph design. Now, on the hunt for the perfect hairspring supplier! Check out the progress if you're curious. https://thebitcoinwatchmaker.com/post/view/fine-tuning-my-watch-movement-a-day-of-progress/
Fine-Tuning My Watch Movement: A Day of Progress
Today was a significant step forward in designing my 36,000 vph watch movement. With the invaluable help of ChatGPT, I tackled key areas like refining the balance wheel and hairspring, choosing the best materials, and fine-tuning my calculations.
-
Balancing the Wheel and Hairspring
For my movement to function at 5 Hz, I needed the right balance wheel (8.25 mm, 6.3 mg·cm²) paired with a precise hairspring. After some detailed calculations, I determined the ideal CGS number (K) to be 22.43 dyne·cm²/rad (or 224.3 N·mm³/rad in SI). ChatGPT helped break down the complex formulas and get everything just right.
-
Material Selection
Choosing between Glucydur, beryllium copper, and brass was tricky. Glucydur offers superior stability, while brass is easier to machine. With ChatGPT's input, I weighed the pros and cons and made an informed decision for my balance wheel.
-
Perfecting the Numbers
Precision was key, so I worked through the NIHS standards to ensure my balance wheel tolerances were spot on, with ChatGPT guiding me through the calculations for tolerance classes like js7. This gave me confidence in my design's accuracy.
-
Sourcing
Im trying to source a hairspring now that I know the numbers, hopefully I find someone willing to sell them to me.
TLDR:
Today's progress, supported by ChatGPT, brought me closer to realizing my high-frequency watch movement. From calculating the perfect hairspring to choosing materials, everything is falling into place!
