and I've learnt something new - that there is a civilian version.
I remeber when I was hunting my 3H bund, that I was steering clear of potential civilian versions, as a) I wasn't aware such a model existed, and b) at that time, there were lots of thin case (aka Squale 50atm) supposid versions on the market for sale - obviously the forgers dream, to stick a blanpain dial into a cheap squale case.
I can see that yours has the good think case, and as you say, non drilled lugs for the civilian model, and I guess it probably has a ratcheted uni-directional bezel?
I wonder how many civilian versions that where genuine I passed on for fear it didn't exist / wasn't real, because importantly as you say, I also would love to have one that I could use underwater.
You've got a great example there!!
