The person in that picture wanted to try this as an intellectual experiment with no practical purpose.
I remember him wearing a "trustless clock," which was based on Bitcoin's timestamping protocol.
It's something that's particularly ineffective as a watch if you know a little about how Bitcoin timestamping is computed.

Oh so he is like the BTC Sessions of watches. Instead of wallets he tries watches. I get it! Tongue

Seriously I am always in favour of trying new things and experimenting with new ideas.
Having said that, I would try to make it work, but just to get the DIY satisfaction.
Watches, in my opinion, are still accessories that need to be more stylish than feature-rich. I am wearing a smartwatch though, so I guess you shouldn't take my word seriously Tongue

Apart from a feasibility study and "we can do this", I can't find a good reason to wear a crypto wallet as an ugly plastic signal colored "thing" on my wrist. This defeats my preference to keep a low profile and not let my surrounding wonder what kind of a strange watch I wear, if I had such a thing (I won't).

I am not a big fan of this type of smart watches with their boring design, but support for code is more important.
If you ask me I would much rather use some retro design similar to casio watches.

Speaking of watches, I had a chat with Valerio Vaccaro, and he made me notice this:

<--image removed from original post-->

He also confirmed that the twatchs3 is compatible with Lora and Lorawan, but of course, Jade does not support this as it requires a lot of software to be added, and this would significantly increase the surface of attack for a wallet.

I 've no particular experience in watches or bands, but, having seen your conversation above, I 'd like to ask what is really the purpose for wearing a hardware wallet as a watch, apart from it being fancy.

At the same time, I 'll tell the truth... the watch in the picture, is kinda ugly in my eyes, am I the only one?

Here is another great video from Crypto Guide with more DIY hardware wallet devices using nlockstream Jade firmware.
With new devices he used you can see huge improvements with bigger screen on some of this devices:

I am copy-pasting all links posted on his youtube channel, and you can follow instructions on video posted:

does anyone know what is common function or usage of LoRa SX1262 on TWatchS3?

LoRa ^{(abbreviation stands for "Long Range")} is the communication protocol is designed for wireless long range communication at low power consumption, thus ^SX1262 module secures the relevant connection between this smart-watch and other LoRa capable devices.

Interestingly, Valerio Vaccaro, one of the engineers working at Blockstream (not sure if or how he is involved in Jade development), is a big supporter of LoRa:

[Total privacy Bitcoin]: off grid Transactions LoRaWan/goTenna

maybe h0es the mastermind behind this move.

Are you saying to me that it is now possible to have a merit wristband, a jade and a watch in the same device?

Probably, but let's see if someone test how everything works... maybe CryptoGuide from YT, he likes DIY bitcoin stuff.

I didn't read this thread for a while, so i just found out about commercial ESP32 smartwatch. I guess it's one more ways to hide or move Bitcoin wallet stealthily, although i doubt it'll work on border that may ask you to give access to all devices.

You can always flash the watch with regular watch firmware code, and load back Jade code when you cross the border.

And while we're at it, does anyone know what is common function or usage of LoRa SX1262 on TWatchS3?

Based on some information I found, it can work similarly to GPS to track the person wearing the watch. It's used for wireless communication and data transfer over longer distances. It can collect data about you, like health monitoring. The module can also become part of a wider system like smart homes, where it allows you to control various appliances from your watch.

Regarding Jade OG reading post here, that would be interesting.
I doubt, but it would be very helpful!

Interesting new update from Jade developers with adding support for esp32s3 DIY devices TTGO TWatchS3 and M5Stack CoreS3.
This means that anyone can finally have a bitcoin smart watch with Jade code for only around 40$.
Maybe someone from Jade is reading my posts because I was recently writing about this Wink

You will only know for sure if you try. Support personnel surely don't have such knowledge, but they could forward your inquiries to the right department. But you also have to keep in mind that there is no way for their developers to know if the wallet will be functional with a non-supported and untested hardware component if they haven't personally conducted similar tests.

I am thinking about trying it since the T-displayTTGO from Lilygo the model unit is ESP32 development board I found much cheaper one around $3 with no LCD and $7 with LCD much similar to T-display(Lilygo). It looks compatible since LNbits DIY hardware wallet mentions that they support T-display(LilyGo) or any version of ESP32 so maybe the blockstream jade firmware supports any ESP32 since they both have a similar model I'm sure it won't work on ESP32 with no LCD because you can't able to navigate but the one with LCD I believe it would work.

In case it doesn't work then I found another option not only LnBits support this but also uBitcoin Hardware wallet.
I found them from this video $10 bitcoin Hardware Wallet, DIY/FOSS/ESP32/easy build!

I got the warning, "Do not attempt to flash the Blockstream firmware to DIY hardware," so that means it's not possible?

The warning message on GitHub is to not flash a DIY firmware on an official Jade hardware wallet. It's surely there because they can't guarantee that your device will work as advertised and if you break it, it won't be covered by the warranty. The Jade doesn't come with a written warranty, but I have read that you can contact the support within a year of buying your device and there is an unofficial type of warranty and support.

I'm sure if I ask Blockstream they won't tell me the truth if their firmware will work because they're promoting LilyGo vendor.

The real question is, can it and does that particular model work? Have you checked this GitHub source? There is mention of some Lilygo displays there. If I were you, I would ask the Blockstream support or open a new issue on GitHub before buying the display to get feedback from them first.

Well, it just looks similar. I got the warning, "Do not attempt to flash the Blockstream firmware to DIY hardware," so that means it's not possible?
As you can see on the image, all components look the same, even on the back, which makes me think maybe the firmware from LilyGo will work on this unit?
I researched a bit yesterday and I heard that you need to replace the driver to be able to flash it with other custom firmware. I'm sure if I ask Blockstream they won't tell me the truth if their firmware will work because they're promoting LilyGo vendor.

In any case, I wouldn't use a DIY wallet on unsupported hardware to hold even only a few precious satoshis.
In case of any problems, expect way less support (if any) than if you went out using supported hardware.
I think the risk/reward ratio is too high for me.

I agree with filippone, I have been there and I can assure you that you don't wanna get in that position. There is no support at all. And it's perfectly normal because they couldn't offer support for every type of hardware.

It seems I found something similar with wireless wifi and Bluetooth module I was planning to try it if it can able to flash with the Blockstream jade firmware.
