This is a top‑tier custom build of the Patek Philippe 5167A “Black Hand Grenade” (Aquanaut) – the stainless steel reference known for its sporty, casual design and distinctive tropical/lattice dial pattern. The “Black Hand Grenade” nickname references the Aquanaut’s unique textured dial and robust, tool‑watch aesthetic. This build focuses on case accuracy, dial quality, and movement finishing.
—The case is CNC‑machined from original specification data using steel. The 5167A features a rounded octagonal bezel inspired by the Nautilus, but with a more contemporary, sporty profile. The case follows correct Aquanaut proportions, including the integrated lug design, proper crown guards, and correct case thickness. Steel provides a clean, durable finish at an accessible price point.
—The dial, hands, and date wheel are top‑tier aftermarket components developed from original data. The 5167A dial features the correct Aquanaut tropical/lattice embossed pattern – a distinctive textured surface that resembles a hand grenade’s surface (hence the nickname). The black dial has a deep, matte finish with applied hour markers and correct logo placement. Hands match genuine proportions. The date window at 3 o’clock follows correct font and alignment. Aftermarket components at this level are designed to be visually indistinguishable from factory parts.
—The movement is powered by a custom‑molded non‑indexed integrated 324 clone. “Non‑indexed” means a free‑sprung balance with no regulator arm – matching the construction of the genuine Patek Philippe 324 caliber. Features include gilt (gold‑toned) engravings on the bridges and an 18K gold rotor. The custom‑molded integrated design ensures correct movement thickness, proper hand stacking, and reliable timekeeping. The free‑sprung balance is a hallmark of higher‑end clone movements.
—Who is this for? Collectors who want the sporty Aquanaut 5167A “Black Hand Grenade” with accurate case proportions, a correct tropical/lattice dial, and a non‑indexed 324 movement with 18K gold rotor. The “Black Hand Grenade” design is one of Patek’s most recognizable modern sport watches. This build targets buyers who appreciate the Aquanaut’s unique textured dial and want a top‑tier custom version. For those seeking the 5167A aesthetic with a premium movement, this build delivers a complete package.
