It features a fully functional column-wheel chronograph mechanism, allowing for crisp start, stop, and reset engagements. The architecture bypasses non-functional decorative plates, delivering a genuine 72-hour power reserve and a highly fluid sweeping seconds hand.

• The High-Contrast Black Dial: The dial utilizes a deep, glossy black finish that perfectly contrasts with the metallic silver-ringed subdials (running seconds at 6 o’clock, 30-minute counter at 3 o’clock, and 12-hour counter at 9 o’clock), exactly as captured. The applied white gold-tone hour markers and hands are densely filled with premium Swiss-grade luminous material for maximum low-light visibility.

• 904L Steel Case & Engraved Bezel: The 40mm case is precisely milled from proprietary 904L stainless steel to achieve an authentic mass and superior corrosion resistance. It features the classic 116520 polished steel bezel with a deeply engraved tachymetric scale, filled with specialized black enamel for exact aesthetic replication and long-lasting durability.

• Classic Oyster Bracelet & Clasp: The watch is mounted on the rugged three-piece link Oyster bracelet crafted entirely from 904L steel. The outer links feature a refined satin brush, while the center links are mirror-polished. It is secured by a robust folding Oysterlock safety clasp equipped with the Easylink 5mm comfort extension link for precise sizing adjustments.
