PATEK PHILIPPE AQUANAUT BLACK DLC/PVD PAIRED WITH A RED STRAP

Same customized-Aquanaut family as the others — black DLC/PVD case and bezel this time paired with a red strap, grey tropical dial, and a red seconds hand plus red minute-track accents.

• Dial: Grey waffle-textured, Arabic numerals at 1, 2, 4, 5, 7, 8, 9, 10, 11, 12
• Accents: Red seconds hand and red minute markers, matching the red strap
• Case/bezel: Black-coated, standard Aquanaut rounded-octagon shape
• Strap: Red rubber, waffle texture, tang buckle
• Date window: At 3 o’clock

Same note as the other black pieces in this set: Patek doesn’t produce this red-on-black colorway from the factory, so it’s most likely a third-party DLC/PVD customization job — worth confirming with whoever’s selling it whether it’s disclosed as customized and how that affects pricing versus a stock piece.
