Ternos professional tt 500m diver automatic 42mm black-blue 16155945
The abbreviation TT is not unknown. A car bearing the same two letters stands for tradition and technology. This aspiration is easily fulfilled by the reworked Ternos Professional TT: it is water-resistant to a depth of up to 500 meters (50 ATM), can automatically regulate gas pressure via a helium valve and a bicolor, a rotatable bezel that now provides visual support for the 15-minute limit before resurfacing. This last feature is what really gives the Ternos Professional TT its name: Two Tone – in either blue-black or grey-black.
Sizing & Fit
The watch functions perfectly. The bezel is impossible to turn with gloves on , and the clasp is cheap . I have gotten tons of compliments . But as an underwater welder / pipefitter I need a working bezel and a better / stronger clasp . I thought this could be an alternative to my Omega . I will continue to use during work so time will tell ( No pun intended ) . Maybe the bezel will loosen and I may try a rubber band
