Casio Moon Graph GMW-15 | Animated moon phase watch with sunrise, sunset, and moon angle data

#Casio #MoonGraph #GMW15
Today's vintage, retro watch review focuses on Casio's Moon Graph watch - the GMW-15 - featuring moon phase data, moon hour angles, sunrise and sunset information all in a dedicated, animated display. Based on your timezone, latitude, and longitude information this moon phase watch will calculate the lunar calendar alongside four daily moon hour angles showing you exactly where in the sky the moon is visible.
For vintage watch collectors, this model pairs nicely with the CGW-50 Cosmo Phase watch. It was a futuristic, astronomical wonder back in its day and remains so today. Be sure to watch until the end to see a special Easter egg that Casio included. Thanks for watching!
