How do I change a Rolex band?

Insert a Rolex spring bar tool into the lug holes, or alternatively, the gaps for the spring bars at the end of the band. Gently retract the spring bar by pressing it with the tool until the band dislodges. Put the new band onto the spring bar. Line up the spring bar with the lugs and use the tool to navigate it into place until it clicks securely. Browse for authenticated Rolex timepieces and bands on 1stDibs.
