OK Chaps, here is the next new feature on the Super SUB which none of the previous models had........ a crown tube o-ring.
As you already know about the 5000 Feet depth rating, you can see that Doxa took the extra precaution to ensure water tightness. The o- ring is beneficial over the whole depth range, not just at extreme depths which it honestly will never see.
It's just one more small improvement which is adding up to making the Seaconquerer the best Doxa SUB ever.
Sorry about the crappy photo. Just playing with lighting at the minute trying to get some decent pics of the watch for you all.
