Caseback for Tissot Chrono XL

About

Protect your oversized chronograph with our replacement casebacks for the Tissot Chrono XL . Measuring in at a bold 45mm, the Chrono XL requires a wide-diameter caseback that maintains a perfect seal to protect the Swiss quartz movement. Whether you are replacing a back damaged during a battery service or restoring a scratched Chrono XL Classic or NBA Edition , our parts provide a precise fit. These casebacks are designed to maintain the 10 bar (100m) water resistance that the Chrono XL is known for. Technical Specifications: Oversized Fit: Specifically engineered for the 45mm case architecture of the T116 series. 316L Stainless Steel: High-durability construction with a brushed or polished finish to match your specific model. Compatibility: Fits major references including the T116.617 (Quartz Chronograph) and T116.417 series. Sealing Integrity: Designed to work seamlessly with Tissot-standard gaskets to prevent moisture ingress. Locating Your Reference Number? The Tissot Chrono XL has its reference number (e.g., T116617A) engraved on the original caseback. We are always expanding our inventory to include PVD black and vintage-style finishes.
