UmiF Edition — Seamless Red Nylon Strap
The UmiF (Umi Factory) iteration of the RM 67-02 “Charles Leclerc” represents a significant technical achievement in replica case construction. By utilizing meticulously layered White NTPT carbon and stripping away redundant movement plates, this specific release achieves an uncommonly thin 8.4mm profile and an astonishing total weight of just 35.7 grams, closely mimicking the ultra-lightweight ethos of the genuine article.
Powering this reference is an Asian heavily modified CRMA7 clone caliber. Rather than a true tourbillon escapement—which is often erroneously stated in grey-market titles—this movement features a custom skeletonized architecture with a visually dynamic moving balance gear positioned at 7 o’clock. This mechanism accurately simulates the kinematics of the genuine free-sprung balance wheel, offering approximately 36 hours of power reserve.
The 39mm chassis exhibits the distinct damascene-like striations inherent to high-grade NTPT carbon machining. The dial flange features precision-painted accent tones that contrast sharply against the skeletonized titanium-toned bridges, while the seamless red elastic nylon strap ensures an ergonomic, flush fit against the wrist.
