Thanks for your post this brought back some memories, I learned to dive in the early 90s and was lucky enough to receive this for my 18th. I believe it was available at the same time as your version, but was analogue. It has depth, max depth and an ascent rate warning if I recall correctly. It shared the same strap as yours with the decompression charts.
It’s been at the bottom of my drawer for ages, but I have started doing some snorkelling with my son and plan to hand it on to him.
