Once you have identified the correct type of screwdriver and inserted it into the notch, it’s time to turn it. Remember, you need to turn the screwdriver counterclockwise to loosen the back. Use steady, even pressure and avoid applying excessive force.

As you turn the screwdriver, the back will gradually unscrew from the case. Be patient and take your time to ensure you don’t damage the watch or the back.

Tips for Turning the Screwdriver Counterclockwise

Tip Description

Hold the Watch Steady Use your non-dominant hand to hold the watch firmly in place while turning the screwdriver with your dominant hand. This will prevent the watch from slipping and minimize the risk of damage.

Apply Gentle Pressure Use steady, even pressure when turning the screwdriver. Avoid applying excessive force, as this can damage the back or the screwdriver.

Turn Slowly Don’t rush the process. Turn the screwdriver slowly and carefully, checking regularly to see if the back has loosened.

Use a Proper-Sized Screwdriver Make sure you are using the correct-sized screwdriver for the notch. A screwdriver that is too small will slip and damage the back, while a screwdriver that is too large may not fit properly.

Avoid Overtightening Once the back has started to loosen, do not overtighten it. Turn the screwdriver until the back is just loose enough to remove by hand.

Caution: If you encounter any resistance or difficulty while turning the screwdriver, stop and reassess the situation. You may have identified the wrong notch or selected an incorrect screwdriver. Continuing to force the screwdriver may damage the watch or the back.

How to Open a Watch Back with a Spoon

Opening a watch back with a spoon is a simple and effective method that requires minimal tools. Here’s a step-by-step guide to help you get started:

Step 1: Gather Your Materials

You’ll need the following:

A watch with a screw-on back

A spoon

A soft cloth (optional)

Step 2: Prepare the Watch

Place the watch face down on a soft cloth or a flat surface to prevent scratches.

Step 3: Locate the Watch Back Notches

Examine the watch back for small notches or grooves located around the perimeter. These notches provide access points for the spoon.

Step 4: Insert the Spoon

Align the spoon’s edge with one of the notches and gently insert it between the watch back and the case.

Step 5: Pry Open the Back

Slowly and carefully pry upwards on the spoon to create a small gap between the watch back and the case.

Once the watch back is loose, gently lift it away from the case. Be careful not to damage the watch or its components.

Additional Tips:

Use a spoon with a rounded edge to avoid scratching the watch.

Apply gentle pressure and avoid using excessive force.

If the back is particularly tight, you can use two spoons to apply more leverage.

If you encounter any resistance, stop and try a different notch or method.

Handle the watch with care and avoid touching the movement or delicate components.
