Two months ago I got a minor leak on my Nauticam GH2 housing while filming at 80+ meters.
Miraculously I managed to avoid soaking my camera and lens: at the end of the dive I had an half glass of water into the dome but everything was perfectly dry.
Opening the housing I did not find any clear evidence of fault: no hair or dirt on the o-ring so I returned the housing and 7-24 dome at Nauticam Italy (it is still under warranty).
Housing and dome was sent to Nauticam HK, pressure tested and inspected. It was ok so it was definitively my fault
Anyway given that one year of intense use was passed already, they completely disassembled it, serviced and returned to me WITHOUT ANY FEE (not even shipping cost).
I was far from home so I sent housing and port without boxes. I received them with brand new boxes and it was so shining (it had again the plastic film on the display) that I had to check its s/n to be sure it was mine...
What can I say more? Nauticam all the life And kudos to Nauticam Italian dealer for his professional service
I even got a short movie from that dive prior to escape to the surface (one and half hour later...). In the original footage I can hear the scary leak alarm
