Precision Power & Perfect Fit — Restoring a TAG Heuer Professional

Welcome back to another Before & After Repair Spotlight! Today, we’re featuring a TAG Heuer Professional 200M Quartz (Model WJ1110, Serial SH1997) that arrived at our facility for bracelet sizing, battery replacement, and performance monitoring.

While a quartz watch may appear “simple” to service, a professional battery replacement on a precision Swiss timepiece is anything but. This TAG Heuer Professional—part of the brand’s sport-driven diving heritage—required more than a quick swap. By addressing both functionality and fit, this timepiece was restored to optimal performance, powered accurately and sized perfectly for its owner.

The Details of This TAG Heuer Service

For this TAG Heuer Professional 200M Quartz restoration, our team performed the following:

Standard & Complimentary Professional Evaluation: As with all repairs, we only provide formal diagnostics once our Certified Watchmakers physically assess the timepiece inside our secure, Swiss-standard facility.
Initial Diagnostic Testing: Advanced testing equipment was used to evaluate the quartz movement, circuitry, and coil, ensuring no underlying issues existed beyond the depleted battery.
Battery Inspection & Voltage Verification: Our technicians identified and installed the precise silver-oxide battery required for this model, ensuring correct voltage and long-lasting performance.
Gasket Inspection & Replacement: All internal seals were inspected to protect the watch’s water resistance, an essential step often skipped by uncertified repair shops.
Precision Case Resealing: Using specialized Swiss tools, the case back was resealed to manufacturer specifications.
Certified Pressure Testing: Every battery replacement includes pressurization testing to verify that the watch maintains its original water-resistance integrity.
Bracelet Sizing Adjustment: The stainless steel bracelet was professionally resized for a secure and comfortable fit, maintaining factory alignment and finish.
Performance Monitoring: After servicing, the watch underwent controlled performance monitoring to confirm accuracy and stability before shipment.

And voilà! This TAG Heuer Professional was returned fully powered, properly sealed, accurately running, and comfortably fitted to its owner’s wrist.

Why Professional Battery Replacement Matters

A battery replacement should never compromise the structural integrity of a Swiss timepiece—especially one engineered for sport performance.

Opening a watch in an uncertified environment can:

Void the manufacturer’s warranty
Compromise water resistance
Introduce microscopic dust into the movement
Damage threads or case components

At My Jewelry Repair, we don’t “just change batteries.” We perform a technical restoration. Every watch battery replacement includes gasket inspection, professional resealing, and certified pressure testing inside our ISO 7 and ISO 8 clean room environments—designed to meet manufacturer-grade standards.

Many local jewelers and kiosks lack the tools and diagnostic equipment required for modern quartz timepieces. In fact, numerous retailers send their watches directly to us for certified servicing.

A Closer Look at the TAG Heuer Professional 200M

The TAG Heuer Professional 200M line is known for its sport-forward durability, clean dial architecture, and dependable quartz precision. Built to withstand daily wear and aquatic activity, maintaining its water resistance through proper gasket care and pressure testing is essential to preserving both performance and resale value.
