Need help with my microsonic LED watch

[morganboy]

I have a microsonic LED watch from the 70's and I don't have any idea what the model number is. I also don't have the users manual. I need to know which way the batteries go into it, also does it have a gasket? The back is off the watch and the batteries are gone, I do have the battery type and saw the same watch for sale on ebay, but they list no model number either. Unless the model number is UHR RELOJ

I've also goggled it and didn't find much more information

It's the only LED I have right now I got a couple of LCDs, someday that Pulsar or one of the other really nice LEDS

Hi morgan.
A lot of the time, each battery well will have a slightly different shape at the bottom of the well. One will be bevelled at the bottom, and one will be a 90 degree angle.
This corresponds to the different shape each terminal of the button cells have. The negative terminal should be placed face down in the bevelled well bottom, and the positive battery terminal should be placed face down into the well without the bevel.

Otherwise, the conductive area at the bottom of each well will be larger for the positive terminal, and smaller for the negative terminal (this is because the negative terminal of a button cell has a positive outer ring beyond the seal which mustn't touch the negative watch terminal).

Make sure the batteries aren't too thick.......you don't want to crack the PCB.

UHR RELOJ means "watch" in German and Spanish respectively (helps the seller reach a bigger audience).

I don't know about a seal, but it probably did have one. Setting should be extremely simple, so a manual shouldn't be necessary.

Good luck !
Rgds.

Charger105,

Thanks for both responses, I will check out the battery compartment and see if i can make any headway doing that. You said something I didn't want hear, that it might have had a gasket Its been sitting in a jewelry box for I 'll bet at least 30 years, I think I bought it back in the late 70's. I don't see a gasket around anywhere. I'm one of those neat freaks, so when I have something apart I usually put all the pieces in a bag.

Yeah pretty sure I can figure out how to set it, but I was hoping a manual would show the bat configurations, maybe the back and if it had a gasket.

I may have the instructions around somewhere, going through a major reorg of my house.

My niece was just down under a couple of months ago, unfortunately for my nephew its spring going on summer here and that's the only time he could take time off.

I'm going to test out trying to add a photo again, its a picture of the back on my watch showing the battery clip and the edge. Hey do these things have some kind of trick to put the back on again? I'm pretty sure the reason it was sitting with the back off is because I couldn't get it back together. Might have been a good thing at least the battery didn't corrode.

Further investigation and looking at the watch in a better light I can clearly
see marked + and - signs in the bottom of the battery holes. Cool all I have to do is figure out about the gasket.

I also did some more investigative work, and I email that guy on eBay selling what I thought was my watch. Guess what I don't think they are authentic. I noticed the band is not the same as mine, the one on eBay looks like an old Speidel band, also the bottom cover is not the same, the writing is in a different location with respect to the battery clip.

And I discovered an old thread here on DWF talking about the same story .About somebody on eBay selling 70's Microsonics. I think the guy is still using the same old storyline:
Whilst on a weekend break in London, I was looking in the window of a jewellers on Middlesex Street and I noticed an old LED watch.

Yikes I guess you got to do your homework before buying a watch on eBay huh?

:
I wish I did, I bought that watch last year had no problems with it except for changing the batteries, when I opened the back the battery clip just fell out, I put two new batteries in and the clip just sits on the top..but I cant seem to get the back to snap back on...if you work out how to do it let me know
