Fits on standard pins

Most Omega watches use ordinary spring bars, so any strap in the right width fits.

Coming off a bracelet

Omega bracelets have curved end links. Our straps have a straight end, so expect a small gap between the strap and the case.

Spring bars included

Every strap comes with new spring bars. Order by 2pm on a weekday for same-day dispatch.

A new strap for your Omega

The Speedmaster Moonwatch, Seamaster Diver 300M, Railmaster and 41mm Aqua Terra all take a 20mm strap on standard pins, which is what this page shows. Leather suits a Speedmaster or Aqua Terra, while rubber or a NATO makes sense on a Seamaster.

A few models differ: the 38mm Aqua Terra takes 19mm and the Seamaster 300 takes 21mm. Got the Omega x Swatch collab? See our MoonSwatch straps.

If yours isn't listed, measure the gap between the lugs or use our on-screen measuring tool. These are replacement straps made to fit, not Omega originals.

Omega strap questions

What size strap fits an Omega watch?

Most Omegas take 20mm, including the Speedmaster Moonwatch, Seamaster Diver 300M, Railmaster and 41mm Aqua Terra. The 38mm Aqua Terra takes 19mm and the Seamaster 300 takes 21mm. For other models, measure the gap between the lugs or use our on-screen measuring tool.

My Omega is on a bracelet. Will a strap fit?

Yes. Omega bracelets fit on ordinary spring bars, so a strap in the right width goes straight on. The bracelet's end links are curved to the case and our straps have a straight end, so expect a small gap between the strap and the case.

Do these straps fit the MoonSwatch?

Yes. The Omega x Swatch MoonSwatch takes 20mm, so every strap on this page fits. We also have a range of MoonSwatch straps in two-tone styles.

Are these genuine Omega straps?

No. They're replacement straps made to fit Omega watches, not made by or connected with Omega. Every strap comes with new spring bars.
