Here is something I did not know about Waterproof minute repeater - unique piece Yummy ...  

Waterproof to the depth equivalent of 30 metres ...  

I guess though that while diving this function wouldn't be that applicable...

I like the Aqualung look from the same era. The problem I found with these and the Breguet repeaters is that they were almost impossible to hear even in quiet environments. A nice watch anyway. Vte

Thanks for sharing!
