RJ-Romain Jerome has once again teamed up with La Joux-Perret to produce the Moon Orbiter GMT. Taking some aspects of the original model, the new timepiece is home to an automatic flying tourbillon caliber, a made-to-measure movement which has been entirely redesigned.

Unprecedented for the brand, the Moon Orbiter GMT sports an additional complication at 12 o’clock, developed exclusively for this model: a fully-integrated, jumping hour retrograde GMT feature.

The Moon Orbiter GMT marks a break from the previous model with a 48 mm rounded case, made from steel incorporating elements from the Apollo 11 spacecraft.RJ-Romain Jerome’s unique spring piston lugs have been specially adapted for the new round case, ensuring maximum comfort on the wrist.

Bringing a resolutely more contemporary touch, the redesigned hands feature a red tip as“a subtle reminder of the red Moon,” says Manuel Emch. To complete the timepiece, the black alligator strap has been enhanced with a red stitching.
