There seems to be a lot of confusion on the 'net about Aquadive watches and who made them. It appears they were redialled Jenny watches.

This electronic version has a highly modified ESA 9154 Dynotron movement. The watch has an additional depth gauge hand that's attached to a circular copper pressure chamber around the outside of the movement; the front of the movement has been modified to support this extra functionality. It's not clear whether this was an ESA modification or whether it was carried out by the watch manufacturer.

Examples with working depth gauges are rare and these watches are now much sought after. They date from about 1970.
