HUGHES early dot-matrix WITHOUT TRIMMER !?!?!?!?

[retroleds]

And then there are the Hughes that give continuous running seconds, vs. the ones that only show for 3-4 seconds. I can't take this any longer lad's, I'm cracking under the strain!.....I'v got to drink a beer!!!

Seriously, isn't the wide variety just amazing? - and this keeps it interesting and fun.

It's a holiday weekend coming up in the States - "Memorial Day", when we remember our soldiers and others who have passed. I would like to thank all of you for all the great threads and fairly low "bitching" over the last few months. And THAT makes it fun, interesting and worthwhile for me. 8)
Peace,

This is by far the my favorite thread here in a long time. :) That's a REALLY early case back date. It wouldn't surprise me if the trimmerless Hughes went back to late '73 but the case back dates have no bearing on the module dates. They could have had those plates made months before the cases were finished or the modules fitted.

Thanks for the photos...That goes for everyone too.

My favorite thread is:
"I'm looking for this and this ,if you have it ,send me an email"
Isn't it better?

[azimuth_pl]

and I know where that thread comes from 8)
a very impatient fellow (status Nerd) who would like to go the easy way.

perhaps some rules of behaviour for newcomers would prevent such "spamming" and not ask useless questions or at least place them in the correct category.

[CompuChron]

eh wait wait!

I don't blame anybody here , just wanted to be funny.
We need newbies and new members.
Even if they choose the "easy" way.
There are not so many post that we need a spam filter, do we?

Maybe I should ad some dirty words to keep this thread alive and bitchy?

[azimuth_pl]

I don't mind only that the Newbie has been emailing me with 10 emails per day shooting questions without any structure, so perhaps that was the reason for my idea of filtering information. some rules might however be helpful.

Wow, this is a great thread. I have the very same CompuChron watch as Azimuth, i'll pull it out later and compare modules. If there are any differences i'll post pictures.

Another one to the list...





No trimmer/hole for a trimmer, AM dot in the time and a very interesting brass cover over the wire bonds instead of the usual black plastic. Anyone seen that before.

One point about the watch case, its got a purple crystal instead of red..???

[azimuth_pl]

this is one of the earliest. the brass cover might be the same as in the early ones which had these painted black (if I'm not mistaken).

One point about the watch case, its got a purple crystal instead of red..???

Looks like a Uranus case...other than their calc., all their regular watches seemed to have a purple-red screen, like port wine. And their buttons line up with Hughes modules, so they(Hughes) make a good replacement.

[Majestyk]

I want it! Even if it's dead.

First Module: (The one in azimuth_pl's photo) "Dot Matrix" Display. Time and date only, no colon. Has Am dot within time. Button contacts soldered to the PCB. No Setting Procedure (Combination of buttons to have to set). Pressing both time and date button gives you seconds. Very early ones had no "+" & "-" inscribed on the battery plating.

Second Module: Same but Hughes did away with the AM dot within the time. (There is a bulletin that comes with the early watches with these modules describing the omission of this). Button contacts soldered to the PCB. No Setting Procedure. Pressing both time and date button gives you seconds.

Third Module: Very rare! Came out late '75. Same features as module #2 but has the bar segments. So Hughes went to this display before adding the newer features. Not many of these were made as it was a short bridge between module "2" and module "4", which also came out late '75. Button contacts soldered to the PCB. No Setting Procedure. Pressing both time and date button gives you seconds.

I read through Majestyk's info again to double check, could this be another type of 29mm Hughes module. Bar segment digits, no colon, AM dot (not in the time display) with the date only, press the time and date buttons to show seconds.

Here's a few pic's...








Inside on the case back its dated 5/74 I don't think its ever been off because of the grime build up, so I'am sure its original. And its not got a brass cover on the module...???. I only got the watch today so please excuse the state of the face I've not had time to re-polish it yet...

[Led-Time]

I thought I'd post this in the old Hughes module thread, I was changing the batteries on a Wittenauer Polara watch today and thought I'd give the contacts a clean when I opened it up something looked different instead of the usual cover over the digits this one has a cover over the whole front of the module like the 25mm version.

Here's a couple of pics of it alongside a normal 29mm module...

[azimuth_pl]

IMO it's a standard module :)
the front mask was used on some models so that the white ceramics on the outside would not be visible.
under the mask you can clearly see the rubber spacer gasket that was used for most Hughes 29mm modules. the gasket must have glued the module and mask together.
remove the mask and the gasket and you should get a standard module :)

btw. here is another missing link showing that standard 29mm Hughes modules were sold or ready to be sold already in 1973.
despite this fact the 1974 BigBlock had its own modified version of the Hughes 29mm module.
