The Rolex Daytona Zenith "Leva di Blocco Originale" 4030-8200 is a rare and collectible version of the Rolex Cosmograph Daytona, featuring the Zenith-based Caliber 4030 movement. This model belongs to the five-digit reference era (16520, 16523, 16528) produced between 1988 and 2000, when Rolex used a modified Zenith El Primero movement before transitioning to an in-house caliber. Key Features: Movement: Rolex-modified Zenith El Primero Caliber 4030, known for its precision and reliability. Case: Classic 40mm stainless steel case with Oyster construction. Dial: Typically features the iconic Daytona chronograph dial layout with subdials at 3, 6, and 9 o’clock. Leva di Blocco: The phrase "Leva di Blocco Originale" refers to the original screw-down pushers, which enhance water resistance and give the watch a distinctive look. Bezel: Engraved tachymeter scale, used for measuring speed. Bracelet: Oyster bracelet, ensuring comfort and durability. Collectibility: This Daytona is highly sought after due to its Zenith movement, which was later replaced by Rolex’s in-house Caliber 4130 in 2000. Enthusiasts appreciate this transitional model for its historical significance and rarity. https://thetimemaker.co/products/4030-8201?_pos=1&_sid=5c4738ebf&_ss=r #timemaker #Rolexparts #Authenticrolexparts
