The incredible Sensor Watch after-market board is really worth a mention on a thread like this: https://www.sensorwatch.net/ https://www.sensorwatch.net/ Joey et al.’s work ports the SPICE astronavigation library to the on board ARM m0 giving you a complete orrery in a classic F91W “Terrorist” watch. It is fantastic! I really love being able to get an estimate of when and where The Moon will rise, or where Saturn is right now. Timekeeping and astronomy are two of the oldest forms of science we have and I love being in constant touch with them via the newest science we have: computers! (The source is all open and available for you to hack on, including a nifty emulator.)

The CGW-50 Cosmo Phase is impressive on that end for displaying realtime planet positions in 1989, now of course it's just another watch face to choose from on Apple. Still I bet the Casio works offline longer :p I'll have to revisit the sensor watch, I'd love to hit a button for sunrise and moonrise

The Yes WorldWatch has the same astronomical almanac but with a display purpose-built for it. https://yeswatch.com/wrist-watch/worldwatch/worldwatchV7-collection.html https://yeswatch.com/wrist-watch/worldwatch/worldwatchV7-col... They're expensive, but beautiful.

  It’s interesting how those watches are both objectively expensive for something nobody really needs and at $1,000 or less, dirt cheap by the standard of expensive watches.

> a complete orrery in a classic F91W “Terrorist” watch It took me a bit of searching, but sure enough: https://www.sensorwatch.net/docs/watchfaces/complication/#orrery https://www.sensorwatch.net/docs/watchfaces/complication/#or... Seems very tedious to actually use, but very cool to have it in the unassuming wristwatch.

  The astronomy face is superior as it calculates the altitude and azimuth of the selected object based on your programmed location and, of course, the current time: https://www.sensorwatch.net/docs/watchfaces/complication/#astronomy https://www.sensorwatch.net/docs/watchfaces/complication/#as... What would be even better would be to acknowledge that altitude is somewhat moot when all these objects are in the ecliptic plane — unsurprisingly Jupiter at Jovian noon is roughly where The Sun was at lunchtime! — and instead cycle through the azimuths of each object in the sky, in the order in which they are visible.
