Hello @Warmond and welcome!
Longines is considered, by far, the best at responding to inquiries about watches the company has previously sold, so you already know everything they can tell you about your watch. On this forum, collectors tend to focus on mechanical watches manufactured and sold before the "quartz crisis" of the 1970s, so I am unsure if anyone here knows the more recent collections all that well. A Longines catalog from the early 1990s is probably the best source to answer your question. If no one here can help you, consider keeping an eye on eBay for Longines catalogs and advertising from that period, as they do appear from time to time.
