Thank you guys, this was a really special and unexpected gift!
The watch is a re-edition of a late 50’s/early 60’s Mido Powerwind diver which was notable for its bright pastel decompression dial ring. Basically you choose your depth and follow the ring around to the minutes you’ll be underwater ( for example 9 oclock = 45 min underwater). The decompression time will be printed within that ring. More of a gimmick of course but fun and more functional than say the decompression ring that Doxa uses. Cant imagine anyone actually using it for that reason but it makes for a good conversation.
Apparently the originals are really hard to come by and go for over $6k. They also made a black dialed version which is more similar to the re-edition.
Comparison of old and new (not my own):

Hodinkee did a great write up on it and IMO it’s a fun little read. I’m really impressed she was able to nab one since they sold out so quickly! Very proud of her and super happy with it.
