Funny the picture shows a subway exit. One of the apps I want from a smart watch is a compass. I work(d) in NYC and I’m always turned around when I exit the subway at an unfamiliar stop.

When I lived in NYC during the Summers of 2005 and 2006 I carried a real compass for this exact purpose.

Walking a block in the wrong direction before figuring it out was not worth going without.

Maybe I'm a curmudgeon, but I have subzero interest in smartwatches, even hackable or open source models. I want my watch to tell me the time, and I want it to do so 10, 20, and 30 years from now without having to fiddle with software. I love Linux. I cut my teeth on it in high school after one too many viruses on Windows XP made me bite the bullet and try debian. I love my Raspberry Pi. It went from retro-gaming con…

Will it?

My guess is that you will need to have it serviced somewhere in that time period.

I am with you in regards to how great an automatic watch is, but unless your seiko has an oil-free escapement of some kind, e.g. silicon or DLC coated, 40 years seems like a stretch.

I found compasses don't work well in NYC either. My phone's compass is always wrong in NYC.

I really wish NYC would paint or engrave a N/S/E/W indicator on the sidewalk at every subway exit.

For cheap esp32-based smartwatches and wristbands, I've had good success with LILYGO and the esp-idf toolchain.

I found I had to wind my Seiko far more often than that. Is this because you wear it daily and the self winder keeps it going? How often do you have to adjust the time?

I adjust the time maybe once every three months, which has naturally fallen into a pattern that lines up with daylight savings time. My watch gains at most few minutes over that interval. There's a single complication for date (1-31) that I adjust on the first day of every month.

Seiko watches aren't the absolute best, but as long as I don't leave it on the shelf for more than 24 hours the self-winding mechanism still works. I'd call them the Toyota of watches.

I'm not a watch-o-phile per se (is there a better word for that hobby/interest?)... More like a /r/BuyItForLife [1] person. Seiko fits the bill to buy it for life without spending luxury good money.

I have a couple of the £30 LilyGo 'TTGO T-Watch 2020' ESP32 based 'watches'. Lots of fun to tinker with and has a colour TFT touchscreen which introduced me to the very impressive lvgl library to create UI. But the battery life is not great (though that teaches you how to write and use deep sleep modes).

An e-ink display would naturally help with the battery life, but the screen refresh times can be an issue for some ideas beyond telling the time.

I'll take one servicing in that period over replacing my watch every 3-5 (2-4?) years as the software becomes obsolete and all support vanishes into the myopically short tech upgrade cycle. It's why I say 'essentially' unsupervised and 'essentially' forever. The point of comparison with smartwatches is so far to the other extreme that I believe the language is largely justified.

Very excited for something like this! I can think of a few fun projects to try that would be useful to me nearly everyday but are too trivial or niche for an Apple or a Samsung to ever spend time actually building. Some ideas off of the top of my head:

- Vibrate a bunch and notify me on-screen if my usual commuter train is running late or cancelled (but only if I haven't left my house yet). Also the same, but in reverse for my commute home

- One-button touch activate my IoT devices (toggle houselights, garage door opener etc)

- Show me how many bikes/docks are left at my local citibike station

- One-button touch to fake a phone call to my phone to get me out of a meeting/conversation in a pinch

- Show me how many minutes until it's predicted to rain

Nothing life changing, but a fun side project that will continue to be useful once it's finished by saving me 5-10 seconds here and there!
