Earlier in 2023, Rolex unveiled the latest generation Daytona, along with its all-new caliber 4131 automatic chronograph movement.
On the occasion of the 100th anniversary of the Le Mans race, Rolex announced yet another new chronograph movement in 2023, the caliber 4132. This movement takes all the enhancements and specifications from the caliber 4131, and extends the elapsed time from 12 hours to 24 hours, thanks to a special in-house developed add-on 24-hour differential (pictured below).
At launch, the caliber 4132 is exclusively available in the all-new 2023 Rolex Daytona Le Mans Anniversary Edition, offered in white gold, with an open caseback.
