I found an orange watch that I like! It’s called Mergulhador MRG3. Apparently it’s a revival of an original 1970’s dive watch.

“Originally designed and produced for both military and civilian use in the Portuguese market, the Mathey-Tissot Merghulador (Merghulador in Portuguese translates to "diver" in English) has, over the years, become a favorite among collectors and enthusiasts of vintage dive watches.”
