Neat! Definitely looks mid-'90s. I know nothing of this Submariner-like model, but would not describe it as a bridge between the De Luca and Rainbow sieries. They were both chronographs, and 'sporting', or 'yachting' watches rather than real divers, although there are dial style similarities between this and the later De Lucas. The last De Lucas were produced in 1996, with the first Rainbows coming concurrently. I will be very interested in what info comes forth re this watch! Where did you find it?
