The stainless steel case anchors the watch in technical robustness, while the rose gold bezel, crown and pushers introduce warmth and depth. Together, these materials define a two-tone composition that plays with balance and visual contrast. Under the sapphire crystal, light shifts across the mother-of-pearl dial, subtly transforming its appearance throughout the day. The signature 3-6-9 overlapping counters remain, preserving a direct link to the original El Primero, while faceted hands and applied indexes ensure clarity in all conditions. The integrated steel and rose gold bracelet extends this interplay of contrast across the entire design.
