Here is a rare Military Diver a Eterna Kontiki Super that was issued to the Israeli Defence Force elite Naval cammando unit,Shayete-13 I have been told and read some stuff on the net.The case diameter 41mm,lugs 20mm,ETA 2824 hacking,quick set date,auto-matic,hand wind movement.And this one is in great shape they were made in the 1970's and this one came with the original bracelet on the latch it is spring loaded to adjust to the wrist.It has the correct marking on the back.There are a lot of fake's out there the price goes up from civilian to military by double.I had a expert look at it before I bought it and thanks Colin if you see this.I also read that the military one's are the only one's that hack so another thing to look for.Here are some photo's.






Here is how the latch workes I pulled on it I have never seen a spring loaded bracelet like this before.
