  My excuse is that I use the watch as a calculator,
  and the battery ran out (-;

  Thanks for your answers.
  I confess I cant read all these specs sheets.
  my value of 7 micro amp, 450 milli volts, per cell in full light, is from this video:

  Hi,

  I want to see if I can convert the watch to "solar" power,
  by adding Vishay Photodiode "BPW34" (https://www.vishay.com/docs/81521/bpw34.­pdf)
  in the corners (left/right to GPS module, and same on bottom)

  According to website, the power consumption:
  ( https://www.espruino.com/Bangle.js#power­-consumption)
  is "100% CPU usage running JavaScript - 7mA",
  and from what I found, this about the same as one Photodiode produces in full sun light,
  so theoretically, it looks possible.

  Does anybody know if this is possible regarding the circuit, or any limitations ?

  Also space-wise, I was searching to see if the files of the case and inner frame models, are available anywhere for 3D printing, but couldn't find it, are they available ?

  Thanks for your help,
  Si.
