The front bezels of the RM 37-01 Kiwi is made from Carbon TPT®. The caseback is made from green Quartz TPT®. The caseband uses a gradient of Carbon TPT® /green Quartz TPT®, creating an elegant colour transition from the bezel to the caseback. The dial is in grade 5 titanium with grey Titalyt® treatment. Each candy is painted with acrylic paint and lacquered by hand with some sugar effect.
