It's not about the identical case or not...Your watches are really an Trafalgar UK imported products from Swiss,
and some VERY SPECIAL ones!!! Trafalgar UK brand existed in early 70s and even registered in the Swiss registered Trade Marks database, cca 1977...
Trafalgar Trafalgar Watch Co. Ltd. London, England; registriert am 5.1.1977And I am really glad that You and me and many others have enjoyed this middle 70s Space AGE design...[/b]
Otherwise my documented chronology will disappoint You...and even me...
the 9310 LCD module certainly appeared in 1975 as being a novelty in Europe and one of the FIRST entirely Swiss Made LCD modules...so maybe earlier than even Your Trafalgar Space Age LED watch design... https://doensen.home.xs4all.nl/l2.htmlThus in 1976, such a LED module as in Your Trafalgar may have been quite obsolete for the USA/GLOBAL LED digital watch technology ,
but anyway, still a novelty in Europe and UK... So I will place this special design of the Trafalgar/Aurore ...1975-1976 LED/LCD watches and their specific genuine SS Space Age bracelets, as one of the MOST IMPORTANT and DARING Space Age design in the history of digital watches,a true precursors of watches like the 1977 Catena's Andre Le Marquand Spacesonics LCDs and Zodiac Astrodigit's LCDs!!!
