What is the difference between Rolex Daytona’s 4131 and 4130 movement?

1: Thinner Hour Markers The dial design is more streamlined on the new Daytona​. The hour markers of the 116500LN have a noticeable thickness compared to their predecessors, while the markers on the newer generation 126500LN have been cut in half and are much thinner.

2: The sub-dials of the chronograph are more refined. The three subdials in the previous 116500LN generations are bold and have a thicker thickness, which attracts attention. The sub-dials of the new 126500LN are slimmer, which gives them a more subtle, elegant appearance.

3:Rolex introduced the crown logo to the 6 o’clock position in recent years. The updated Daytona​ continues this trend. This crown logo is positioned between the text “SWISS-MADE”. It makes a distinct difference. It’s a subtle change, but it distinguishes the new generation Rolex watches along with the changes to the dial design.

4: Ceramic bezel with metal ring.Ceramic bezel has a metal edge The metal ring on the ceramic bezel of the new generation Daytona makes it appear smaller. This metal ring protects the ceramic bezel and also compliments the thinner chronograph ring, creating a more refined and cohesive design.

5:The case design is different. While the Daytona cases look similar from the front, the side view shows distinct differences. The lugs of the new generation Daytona are more pronounced and thicker. The connection between strap and lugs was also redesigned to give the watch a more refined and robust look.

6:Upgrade to the movement The new generation Daytona uses the newly developed automatic 4131 movement. This movement incorporates ball-bearings that improve the winding efficiency. The 4131 movement is more efficient than the 4130 because it has the Rolex Chronergy Escapement System and Paraflex shock-absorber. The new movement also features a Geneva pattern polished on the deck. This is in contrast to the old 4130 movement which used a radial design. The overall configuration is similar to the old 4130 despite these improvements. This marks a minor upgrade and not a complete overhaul.
