This work horse! It has gone underwater, jumped out of perfectly flying airplanes, performed car maintenance, yard work and 38 years later still strong!
This is my one, a gift from my concerned wife who wanted me to have a "reliable watch" on a trip to the UK. A vintage watch packed up on a previous trip.
This one. This particular watch was a military purchase previously owned by a US Navy helicopter pilot. Because of this, Omega will service it free of charge for life.
This watch accompanied me through adolescence and all the stupid things I did then. Not only is it still in one piece, but it is still going strong after a bit of spa treatment.
I liked my first Tuna so much I now have 2... This is by far my favorite, pretty much has become my summer daily driver. The thing I really appreciate about the Tuna design is that for such a large watch. 1) it is very light weight being titanium. 2) The underslung lugs give it only a ~42mm or so lug to lug length. It is the smallest wearing big watch I have ever tried on. (I might have to go get the automatic Tuna next...)
