Skmei watches are well built. They are really cheap and I have no allergies with their bands (not like it happens with casio). Sadly they clone casio designs but mimic their mistakes and ads extra ones just to circumvent copyright issues. Wish I could just run #sensorwatch in them instead #skmei #digitalwatches

Die #SensorWatch kann Zeitumstellung. Müssen nur noch die Swatch und Casio-Modelle umgestellt werden…

Today is the #sensorwatch, with a fresh battery and oil filled case as of yesterday. and a bonus not-a-watch

@JC2112 I am just using using @joeycastillo's #SensorWatch board sensorwatch.net with some firmware that includes the includes Beat Time watch face/complication sensorwatch.net/docs/watchface

If using prebuilt firmware it is not too challenging to upgrade yourself.

@CatherineFlick not sure if it would do all the features you mention (especially as it hasn't got Bluetooth), but I like the approach @joeycastillo has taken with the #SensorWatch crowdsupply.com/oddly-specific

@krims Stick a #SensorWatch module in a colourful F-91W case!

Also if you want a universal time you can already do that by offering a time in UTC. Anyway it is still fun and you still find occasional references to it on the internet and in software. Here is one of my #Casio F-91Ws using @joeycastillo's super cool #SensorWatch module to show a time in .beats.

With the screwdriver that came with my eye glasses repair kit, I disassembled the watch, revealing the original #casio circuit board, one of the seven wonders of 1980's consumer electronics.

The Japanese calendar display function has been updated. It has been redesigned for the new customized display. You can display both Reiwa 1 and Heisei 31 at the same time.

Sensor Watch Pro arrived last week for my Casio F-91W with the custom LCD and accelerometer board. Took about 20 minutes to install, including flashing firmware and unnecessary desoldering of a component from the original board.

Really like it so far, light is still relatively dim, but has the ability to set a custom color and not just green. Seems like the Second Movement firmware might have the ability to change the alarm chime to Zelda, Mario or others which I'll have to explore at some point.

The tap capability with the accelerometer board is really useful too, even if it's only working for the Countdown app currently.

Other people with #crowdsupply #sensorwatch #sensorwatchpro orders - do you have dispatch notifications? I'm seeing some people with arrivals, I have the traditional nada from #crowdsupply so far.

Just getting an idea of if anything is remotely in transit, or to go looking for a package hidden in the garden again.

Casio F91w compatible watches are available for purchase from this site. There are many variations available.

It's here! Made it to the in one piece.

The is a drop-in PCB for the iconic F-91W or A158W created by @joeycastillo (Oddly Specific Objects) with lots of cool features!

It's hackable, programmable, and built to be modular. Just my kind of tech.

Now I just need to decide which of my F-91Ws is going to get the upgrade. 😂

Oh look what arrived here in Spain today:

@joeycastillo's Sensor Watch Pro via @crowdsupply 😍

I was a little bit worried doing the watch surgery, as I am rather clumsy, but it took me less than 30 minutes until the watch was back together, and I didn't even need to watch the instruction video!

Well done for such a neat and well-documented package, Joey!

I am holding up the shiny purple carton for the sensor watch pro in front of a lemon and date tree and bright blue sky.A CASIO F-91W watch is lying on a green cutting mat next to its original PCB and display, as well as the Sensor Watch Pro's instruction leaflet.

The watch's display shows the current temperature as 34.04 degrees Celsius, demonstrating that the watch brain transplant was successful.

By way of explanation: I have shipped four variants of over the years, and this is me testing the release candidate firmware on all of them. Because you can’t test a wearable on a workbench alone. You have to wear it.

Got a hackable replacement main board for a hardware classic.

Going to have some fun playing with the custom firmware toolchain. It’s a welcome break from all the cloudy remote automated pipeline stuff I have to work with for a living.

Casino F-91w digital watch from 1989 on my left wrist. It’s a digital watch with an LCD display in a black plastic case with three metal function buttons and a black plastic strap.

The watch face has the words

ALARM CHRONOGRAPH
Water WR RESIST
Mon the outside. The buttons are labelled ( clockwise from lower right) 
Alarm on/Off 24hr

The display is showing a decidedly non standard text:
