Looks like a 1980’s quartz Longines. This was a very dark period for the Swiss watch industry. Many watch companies went bankrupt or close to it. Longines was acquired by Swatch and survives to this day as a subsidiary.
The shower head on the left means it’s supposed to be water resistant. The case looks to be gold plated with a steel back.
I have no clue what the dial design means. Could be a company logo or it could have no meaning at all.
If you want more information, you should take the watch to a watchmaker and have it opened. Be sure to take pictures of the inside. Send them to Longines.

While your watch probably has a lot of sentimental value, it doesn’t have a lot of collector value.
Hope this helps,
