Cannot recognise what a trade mark. No inscriptions on the watch, just a few on the module. 1974th - the year of production?

Amazingly enough, Hughes also made clock chips for Time Computer. Accidental discovery of a Hughes-logoed chip in an original P3 module. I had always presumed, like everybody else, that RCA was the sole supplier of chips for the Pulsar watches...not so.

Reminds me of an interesting thread about the origins of Pulsar IC's back in 2007.

Around about then I had bought a couple totally dead-knackered-wasted-useless Pulsar Calculator watches from ebay for not a lot of $$'s and decided to use them as the first objects to examine under a decent binocular microscope, complete with a medium res CCD camera built into it.

Here's some sample photos. Besides missing nearly every wire bond, the chips came from a variety of manufacturers, most obvious of which was Toshiba, with a 1975 date on the substrate !

I'm so sorry but I didn't understand - I know the module producer, but what about watch itself? Ordinary module from Hughes Aircraft for lots of wacth manufacturers or just not typical module? 1974 - the year of production - or just a coincidence?
Best regards,
Andrew

It's a very common module, they were fitted in lots of different branded cases. I would say 11/74 was the month/year of manufacture, nice that it has the dot display most of the Hughes modules had the line type display.

The most unusual Hughes I ever came across was a dot display with colon and 'advanced' time setting procedure. Someone at the factory must have found some older displays and decided to mount them on the newer PCB's.

A few LED watches in the collection

Cornavin with sensor buttons. Just touch it by hand for watching time. There are two buttons - Mode and setting (a bit lower the surface of the glass). There are hours, minutes, seconds, date, month and day of week.







Ladies LED watch Texas Instruments - the easiest - hours, minutes, seconds, day and month.





Led driver watch JAZ with ETA ЕSA 9290 inside, the glass has a crack.



You can choose hours and minutes ...



… or day and seconds



Funny ladies watch with only two digits. First displayed hours, then minutes. I placed here pics of module earlier.
