ZF Factory Edition — Black Natural Rubber Strap
The ZF Factory edition of the RM 035 Full Transparent Tourbillon represents a distinct technical achievement in replica case construction. By utilizing CNC-machined crystal glass with a 7 Mohs hardness rating, this model achieves a zero-gap integration between the upper and lower shells, a structural benchmark previously challenging for transparent cases.
This reference is powered by a custom manual-winding tourbillon clone caliber, featuring an integrated machine design where each movement bears an independent serial code. Unlike standard skeletonized plates, this mechanism supports a fully functional rotating escapement. Power delivery yields approximately 36 hours of continuous operation under optimal conditions.
Measuring a confirmed 17.5mm in thickness and weighing exactly 86.9g, the case profile is substantial yet visually lightweight due to its transparency. The inner flange is milled from black carbon fiber with diamond-like carbon (DLC) treatment, contrasting against the homologous fluorescent coated indices and grade 5 titanium alloy spline screws.
- Movement: Custom Manual Winding Tourbillon — Approximately 36 hours
- Case Material: Transparent Crystal Glass, 42mm × 50mm, 86.9g
- Bezel: Transparent Crystal Glass, CNC integrated
- Crystal: Scratch-Proof Sapphire with double anti-glare coating
- Bracelet: Imported natural black rubber, titanium folding clasp
- Water Resistance: 30m stated — professional pressure test recommended before swimming
This piece serves collectors analyzing the intersection of avant-garde materials and mechanical complexity. It is best suited for those who appreciate the visual theater of a tourbillon within a fully transparent architecture, acknowledging the inherent dimensional compromises.
