Excellent video. This 1068 watch has been on my motorbike for 2 years in all English weather and works like new. How long should I expect the battery to last? Will a magnet affect it if attached to the back? Thanks in advance.
Thank you. You know.. I would recommend to find quality parts on Mouser or Digikey, or another trusted vendor. This will allow you to calculate and get a predictable result in your project. Search words: 1. Crystals quartz 32.768 2. Trimmers Capacitors Data values: 1. Crystal, tol +/-5ppm or less. load pF and ESR depend from IC. 2. Cap, 1.5-12pF with lowest ppm/ºC.
You know, I bought high quality crystal made by Citizen, Japan for the $1.5 which is giving me accuracy +/- 1-3 seconds per month When a regular crystal will cost approx $0.1 and gives accuracy +/- 5-45 seconds per month.

the advertisement for this watch is that it uses a Taiwanese quartz module. is that true?
Awesome project. Can i ask how i can find the trim capacitor and the crystal quartz on ali express? Search words, data values etc.?
Thank you.
