Movement

The watch runs on a Clone Calibre 240 PS IRM C LU automatic ultra-thin mechanical movement set up within the unique asymmetric dial architecture of the 5712. In addition to hours and minutes, the watch comes with a power-reserve indicator at 10 o’clock, pointer date with a moon phase indication at 7-8 o’clock and separate small-seconds subdial between 4 and 5 o’clock. The off-center configuration makes the dial look mechanically balanced while ensuring clear separation of indications.

Case & Construction

The case with diameter of 40mm is made of 904L stainless steel with alternating cool silver and rose-gold-tone finishes. The central case and upper and lower attachment sections remain silver-colored, while rose-gold-tone sections create a distinctive two-tone color scheme.

Bezel

The rounded-octagonal bezel is made from 904L stainless steel with a rose-gold-tone finish, forming the strongest warm-colored element of the watch. Its broad upper surface receives fine directional brushing, while the outer edges, corners and angled chamfers are mirror polished. Positioned between the dark dial and cool-toned central case, the bezel makes the two-tone construction particularly clear without appearing uniformly bright.

Strap

A black alligator leather strap gives the 40mm case a softer and more formal wrist presence than an integrated metal bracelet. The dark leather continues the visual tone of the charcoal dial while allowing the rose-gold-tone bezel to remain the main accent. With regular wear, the leather naturally conforms more closely to the wrist for a flexible and refined fit.

• Material: Alligator leather
• Color: Black
• Wearing Feel: Flexible leather construction that conforms gradually to the wrist
• Wearing Style: Refined, understated and suitable for both formal and smart-casual wear

Buyer FAQ

1. How is the construction with two-tone 904L steel different from a solid precious-metal case?

This version is made of 904L steel with cool silver and rose-gold-tone finish instead of solid white gold and rose gold. It is mostly defined by the combination of two tones and different types of finishing. The polished chamfers and rose-gold-tone areas need special care and protection from abrasive substances and aggressive polishing.

2. Will the 40mm case be comfortable with alligator leather strap?

A 40mm case has a good wrist presence. Alligator leather strap is more flexible than a full metal bracelet. Leather becomes shaped after some use according to the wrist shape, but personal comfort is determined by individual wrist size and correct strap fitting.

3. What kind of maintenance does the Clone Calibre 240 PS IRM C LU need?

It is an automatic mechanical movement with multiple complications. Professional inspection is recommended to maintain its good condition. Avoid shocks and strong magnetic influence. If you notice that the timekeeping or one of the complications displays behaves unusually, get your watch serviced by a professional watchmaker experienced in servicing mechanical calibres instead of using control devices.

4. Do I need to know anything about water resistance, cleaning and lume performance?

The declared water resistance level is 30M. Therefore, swimming, showering and immersion are not recommended for this watch. Professional pressure tests should be done before any contact with water. Never adjust the crown or pushers while being submerged in water. Use a soft microfiber cloth for cleaning the case and sapphire crystal and keep the alligator leather strap away from water, perfumes and chemicals. The luminous paint used on the hands and indices needs light to glow brightly; otherwise it will fade after some time in the dark.

Water Resistance Notice: Professional pressure test recommended before water exposure. Do not operate crown or pushers underwater.
