The C60 Trident Chronograph is a watch created for diving professionals that non-submariners will covet every bit as much. Water-resistant to 600m and boasting a helium release valve, it’s the ultimate diving timepiece. Description The C60 Trident Chronograph is a watch created for diving professionals that non-submariners will covet just as much. The navy and metallic-yellow dial catches the eye immediately, as does the 60-seconds sub-dial which ‘breathes’ via a rotating disc behind a cut-out for easy reading. The uni-directional ceramic bezel has a better defined font for the numerals, which is filled with SuperLuminova for outstanding luminosity. Water-resistant up to 600 metres (2,000ft), the fluid contours of the Trident case, which also incorporates an automatic helium release valve, surround the self-winding ETA Valjoux 7750 chronograph movement. A stunning watch. Movement Developed in 1974 by movement maker, Valjoux, the 7750 has been the most widely used mechanical chronograph movement ever since. One of the first movements to be designed by computer, the 7750 only winds in one direction and this, combined with the heavily weighted rotor arm, gives the movement a singular sound, produces a feeling that the watch is ‘alive’ on the wrist. It’s a legend – and rightly so.
