Movement

The super-integrated Clone Cal. 240 PS IRM C LU comprises 265 components and beats at 21,600 vibrations per hour with an ultra-thin flat hairspring. All parameters are aligned with the original 240 architecture.

Fully operational functions: power-reserve indication, genuine moon-phase display, date by hand, small seconds and dual quick-set correctors

No simulated rotor covers or decorative shortcuts — the movement delivers the complete functional suite of the reference

Construction prioritises stable transmission and reliable daily performance

Case & Construction

Reproduction of the initial 126 g total weight on a leather strap watch model in the ultra-slim 8.7 mm case thickness proves very difficult. The solution is to create a solid, monolithic case made of copper-free tungsten-steel alloy which is machined with CNC equipment; such one-component case weighs 33 g. The manufacturing has a 80% waste rate and yields a small number of items.

Copper is not included in the material’s composition and there is no steel layer on top of it, which eliminates the peeling effect and colour shifts characteristic for watches with those materials used. Photo galvanisation of a nickel layer provides an effective oxidation-proof layer and the following gold-plating procedure is performed in 360-degree manner using a special formula of rose-gold tone which perfectly matches the original. The finish procedure involves a Swiss PVD transparent hard film protecting the plating.

Dial

Patek Philippe Nautilus 5712R replica chocolate brown dial with horizontal embossing. A custom gradient treatment allows the outer edges to transition naturally from deeper tones toward a softer grey under changing light and viewing angles. The applied markers and hands maintain clear contrast, while a custom sapphire-crystal moon-phase disc with gilded detailing elevates the complication to a high level of finishing.

Bezel

Octagonal bezel executed in the same copper-free tungsten-steel alloy. Fine vertical satin finishing on the upper surface is paired with high-polish mirror edges that produce clean, controlled golden reflections when the watch is turned in the light.

Strap

Brown alligator leather strap paired with a rose-gold folding clasp. The strap and clasp contribute to the overall 126 g weight balance without any artificial thickening, preserving the original proportions and formal wearing character.

Buyer FAQ

Q: Why is matching the original weight on a leather-strap 5712R particularly difficult?

A: Simply exchanging a steel bracelet for leather reduces mass significantly. The only way to restore the full 126 g while keeping the 8.7 mm thickness is to machine a solid one-piece tungsten-steel upper case weighing 33 g — a process with an approximately 80 % scrap rate and correspondingly limited production.

Q: How does the copper-free alloy prevent the peeling seen on other weighted versions?

A: Copper-bearing alloys react with perspiration and can form bubbles beneath the plating. Clad steel layers expand and contract at different rates from the core, causing separation. The copper-free tungsten-steel alloy eliminates both failure modes and is further protected by a nickel underlayer, true gold plating and Swiss PVD film.

Q: Are the moon-phase and power-reserve functions genuine mechanical complications?

A: Yes. Both operate through the full 265-component Cal. 240 PS IRM C LU architecture, together with the date, small seconds and dual quick-set correctors — not simulated or decorative elements.

Q: How does the watch maintain its rose-gold appearance over time?

A: After the nickel anti-oxidation layer and true gold plating, a Swiss PVD transparent hard film is applied. This combination is designed to resist normal daily wear and colour shift far more effectively than conventional plating alone.
