How to Replace Pins and Tubes on Omega Seamaster Watch Links (with Step-by-Step Guide)

Learning how to replace pins and tubes on Omega Seamaster watch links is easier than it sounds. Omega Seamaster bracelets are built to last, but over time they can develop stretch due to worn internal parts. In other cases, your bracelet may feel too tight and you need to insert a new link for a better fit.

This guide shows you how to remove and reinsert the pin and two-tube assembly used in many Omega Seamaster links. Whether you’re replacing worn parts to fix stretch or adding a link, the steps are the same. By the end, you’ll know exactly how to replace pins and tubes on Omega Seamaster watch links using tools you may already own.

What You’ll Need

• Spare pin and tube set (see below for compatible models)

Step-by-Step: How to Replace the Pin and Tubes

1. Find the Arrow

Look at the underside of the bracelet link. You’ll see a small arrow stamped into the metal—this shows the direction the pin should be pushed out.

2. Remove the Pin

• Place the link in the pin remover tool with the arrow pointing toward the pusher.
• Turn the handle slowly to begin pushing the pin out.
• Once part of the pin is exposed, use pliers to pull it out fully.
• Separate the link, and remove the two metal tubes from the larger holes.

Reassembling the Link (or Adding a New One)

Step-by-step reassembly: follow the numbered stages to insert pin and tubes correctly

Understanding the Numbered Steps in the Image Above

1 – The full set of components laid out: two link segments, the pin, and the two tubes you’ll be inserting.

2 – The new tubes are being inserted into the larger holes on either side of the link.

3 – The links are aligned and pressed together, ready to receive the pin.

4 – The pin is inserted correctly from the smaller hole, with the groove at the far end so it locks into the second tube.

5 – This shows what happens if the pin is inserted the wrong way, with the groove facing the first tube—it will not lock properly.

6 – The final result, with the pin fully seated and flush with the edge of the link.

3. Insert the New Tubes

Insert one tube into each of the two larger holes in the link.

4. Align the Links

Push the link segments together so the holes are perfectly aligned.

5. Insert the Pin

Insert the pin from the side with the smaller hole. The grooved end should be as far from the link as possible when starting. It needs to pass through the first tube before locking into the second.

6. Hammer the Pin Into Place

Use a small hammer to gently tap the pin in. Once it’s nearly flush, use the pin removal tool again to press it slightly below the surface for a clean finish.

Done – Your Seamaster Bracelet is Now Secure and Strong

This process works whether you’re:

• Removing sag or stretch from worn bracelet links
• Adding a new link for better fit

These compatible pins and tubes are easy to install and built to last, keeping your Omega Seamaster bracelet secure and solid for years to come.
