Texas Instruments model 103 (Moved Post)

[iggy tee]

Texas Instruments model 103,rare version of the LED watch from the 70s .
The watch is in excellent condition, this version has a built-in photo cell ,so that the display in the dark less bright as daylight illuminates stronger, this is done to save battery power.
With one touch of a button displays the time and after a few seconds off , when you press and hold the button will appear a second, double-click the button and the LED display to date.
This model is quite rare and hard to find, especially in this condition and fully correct.
40 year old watch looks futuristic today, and leaves a strong impression.
Photos realistically represent watch.

(The watch is available for sale, if interested please respond via this post viewtopic.php?f=5&t=7143&p=46022#p46022)

that's a nice one. some of the early TI were good quality, I have the SS with curved glass screen and big digits, I don't think is as a light sensor and if it does
it doesn't work anymore. Back in the day they used some cadmium compound that degrades over time. At one time TI built this nice module with digits as big as Pulsar,
exposed wire-bonds, used on premium watches. never seen one working. This is my fab TI.

It's tempting to buy that watch just for the satisfying job of filling the text on the screen with white paint

I looked and thought the same, although I was thinking of gold - not sure what it would have been originally.

Yeah good point I guess the gold plated version would have been different to the ss.

Just curious, how would you go about doing this? eg with some sort of specialist pen, stencil or paintbrush? I ask as it seems like it would be a v fiddly task as the writing is tiny and it's a painfully meticulous task to freehand it (and requires a super steady hand). I have a few old watches that could do with a logo repaint but never occurred to me (up to now) to actually attempt it. Cheers!

With TI watches it's fairly simple as the logo is deeply engraved into the crystal, just fill with paint and wipe off the excess.

I do have a couple of TI watches I can try that on. Prob less likely to work on some of my LCD's where there isnt the same depth of engraving. What paint do you use? Thanks

Just a small tin of modellers paint, and a fine brush.

I use an 'arts and crafts' paint pen such as item number 351005525925 (various colours available), super easy to do, just dab it into the lettering and don't worry about being too neat with it as the excess will just polish away.

Great tips guys. I'll prob try the pen route first, it's been decades since I've wielded a brush. Thanks
