Roman numerals on a silvered dial, a set bezel, and a steel bracelet: this reference drops the off-centre small seconds sub-dial I see on most of this catalogue, leaving a cleaner, more symmetrical face. That's a legibility trade worth noting — no sub-dial to interrupt the numerals means the eye reads the time faster, even if it costs a bit of mechanical personality. Quartz keeps this precise without complication. Thirty metres of water resistance is standard for the line, present but not the reason to buy this particular reference.
