Overview
Split-seconds chronograph in Carbon TPT®
An execution of the RM 004 split-seconds chronograph with a Carbon TPT® case. The material is constructed from several hundred carbon filament layers, each under 30 microns thick, laid with the fibre direction rotated between layers and cured under heat and pressure. Machining across the layers produces a striated surface pattern that differs between cases.
