Introduction

The Garmin Approach S2 is a GPS golf watch designed specifically for golfers who want accurate distance measurements and course information directly on their wrist. As one of Garmin's early golf smartwatch models, the Approach S2 provides preloaded golf course maps, yardage information to the front, middle, and back of greens, and a lightweight design suitable for all-day wear on the golf course.

Key Features of Garmin Approach S2

• High-sensitivity GPS receiver
• Preloaded golf course database
• Distance measurement to hazards and greens
• Digital scorecard function
• Lightweight and comfortable design
• Monochrome LCD display for excellent outdoor visibility
• Durable polymer housing with stainless steel accents
• Water-resistant construction

Although the Garmin Approach S2 is built for outdoor use, years of daily wear can lead to hardware issues such as cracked screens, battery degradation, damaged back covers, motherboard failures, or worn waterproof seals.

This guide explains how to repair Garmin Approach S2 and replace common components, including:

• Screen (LCD display)
• Battery
• Back cover
• Motherboard
• Waterproof gasket (seal)

Tools Required Before Starting

Before disassembling your Garmin Approach S2, prepare the following tools:

• T5 Torx screwdriver
• Plastic opening tool
• Metal spudger
• Precision tweezers
• Adhesive tape (if needed)
• Anti-static wrist strap (recommended)
• Replacement screen, battery, gasket, or motherboard

Make sure the watch is powered off before beginning any repair.

How to Replace the Garmin Approach S2 Back Cover

Step 1: Remove the Back Cover Screws

Use a T5 Torx screwdriver to remove the six 6.32 mm screws securing the back cover to the watch housing.

Take care to keep the screws organized for reassembly.

Step 2: Remove the Back Cover

Carefully lift the back cover away from the watch.

Even after all six screws have been removed, the back cover may remain tightly attached due to the waterproof seal and years of compression. Moderate to extensive prying may be required.

Be gentle but firm while separating the cover to avoid damaging the housing or internal components.

Once removed, you will gain access to the internal components of the watch.

How to Replace the Garmin Approach S2 Waterproof Gasket

After removing the back cover, the orange waterproof gasket becomes visible around the perimeter of the housing.

Step 1: Remove the Old Gasket

Carefully lift and remove the orange gasket from its groove using tweezers or a plastic opening tool.

Inspect the gasket for:

• Cracks
• Deformation
• Compression damage
• Dirt or debris

Step 2: Install the New Gasket

Place the replacement gasket into the groove, ensuring it sits evenly around the entire perimeter.

A properly installed gasket helps maintain the watch's water resistance and protects internal electronics from moisture damage.

How to Replace the Garmin Approach S2 Screen

Once the back cover and gasket have been removed, you can proceed with screen replacement.

Step 1: Access the Screen Assembly

Ensure the watch internals are fully exposed and accessible.

Step 2: Remove the Screen and Motherboard Assembly

Carefully lift the screen and motherboard assembly out of the watch case.

Avoid applying excessive force, as delicate cables connect the display and motherboard.

Step 3: Remove the Golden Retaining Clip

Use a metal spudger to remove the gold-colored retaining clip securing the screen.

There may be adhesive holding the clip in place, so work slowly to avoid bending the clip.

Step 4: Separate the Screen from the Retaining Clip

After removing the clip, carefully separate the screen from the metal frame.

Inspect the frame and remove any remaining adhesive residue if necessary.

Step 5: Disconnect the Screen Connector

Remove the display connector from the motherboard by pulling it free at the base.

Notice: Always pull from the base of the connector wire. Pulling from the cable itself can easily tear the display cable and permanently damage the screen.

Step 6: Remove the Screen

Separate the screen completely from the motherboard.

Pay close attention to any tape securing the connector to the display. These cables are extremely fragile and can tear easily during removal.

Install the replacement screen by reversing the above steps.

How to Replace the Garmin Approach S2 Motherboard

After following the screen removal procedure above, the motherboard can be separated from the display assembly.

Step 1: Disconnect All Connectors

Carefully disconnect any remaining cables attached to the motherboard.

Inspect the connectors for corrosion or physical damage.

Step 2: Remove the Motherboard

Lift the motherboard from the assembly and remove it from the watch.

Avoid touching exposed electronic components directly to prevent electrostatic damage.

Step 3: Install the Replacement Motherboard

Position the new motherboard into place and reconnect all cables securely.

Before fully reassembling the watch, verify that:

• The display powers on correctly
• Buttons function properly
• GPS operation is normal
• Charging works as expected

How to Replace the Garmin Approach S2 Battery

Since the battery is accessible once the back cover is removed, battery replacement is relatively straightforward.

Step 1: Disconnect the Battery

Carefully disconnect the battery connector from the motherboard.

Step 2: Remove the Battery

If adhesive is present, gently pry the battery free using a plastic tool.

Avoid puncturing or bending the battery.

Step 3: Install the New Battery

Place the replacement battery into position and reconnect the battery connector.

Ensure the cable is routed exactly as it was originally.

Conclusion

Repairing a Garmin Approach S2 is entirely possible with the proper tools and replacement parts. The most common repairs include replacing the screen, battery, back cover, motherboard, and waterproof gasket.

By following the procedures outlined above, you can restore functionality to a damaged or aging Garmin golf watch while extending its service life and avoiding the cost of purchasing a new device.

When reassembling the watch, always verify that the waterproof gasket is properly installed and that all connectors are securely attached. Taking extra care during disassembly and reassembly will help ensure a successful repair and maintain the reliability of your Garmin Approach S2 for years to come.
