The MB&F Legacy Machine collection blends traditional watchmaking techniques with modern innovation. Each luxury fake watches is centered around the concept of "mechanical sculpture," combining precision engineering with artistic aesthetics to create timepieces that are both functional and visually stunning. The following is an in-depth analysis of the collection's five key elements: materials, movement, structural design, craftsmanship, and limited edition production.
1. Material Selection and Processing
MB&F is extremely meticulous in the selection and processing of materials, pursuing both exceptional performance and aesthetic appeal.
Innovative Application of High-End Materials
The case materials include 18K gold, platinum, titanium (such as the LM No.2 Titanium), and zirconium (such as the LM Sequential EVO). Titanium is machined into its curved surface using 5-axis 3D drilling. Combined with sapphire crystal, it meets the technical challenge of achieving a water resistance of 30 meters. Zirconium, renowned for its lightweight and durability, undergoes a special treatment to achieve a unique luster.
Detailed Surface Treatment
The case and movement components utilize a multi-layered surface treatment: brushed, mirror-polished, and sandblasted techniques are applied alternately. For example, the bezel of the LM No.2 titanium edition shifts from brushed to mirror-polished, enhancing the visual depth. The LM Split Escapement EVO's movement gears feature a dark NAC coating, creating a striking contrast with the rose gold components. These treatments not only enhance wear resistance but also highlight the three-dimensionality of the mechanical structure through the play of light and shadow.fake U-BOAT Chimera watches
2. Movement Development and Complex Functions
The movements in the Legacy Machine series are jointly developed by independent watchmakers, centered around hand-finishing and precision mechanical design.
Groundbreaking Movement Architecture
Split Escapement: The LM Split Escapement features a 14mm balance wheel positioned above the dial, with the pallet fork and escape wheel concealed at the bottom of the movement. Connected by a 12mm-long balance rod, they create the visual illusion of a "floating balance wheel." This construction requires meticulously calculated rigidity and flexibility to ensure lossless power transmission.
Twin-Barrel System: The LM Perpetual EVO and LM SE EVO utilize twin barrels connected in series, providing a 72-hour power reserve. Torque output is balanced through independent gear trains, minimizing the impact of power loss on accuracy.
Planetary Differential Technology: The LM No. 2's twin-balance system transmits the average rate of two independent balance wheels to a single gear train via a planetary differential consisting of three large and five small gears, maintaining an accuracy of less than ±5 seconds per day.replica Jacob & Co astronomia sky Watches
Mechanical Integration of Complex Functions
Perpetual Calendar Module: The LM Perpetual EVO's mechanical processor uses a default 28-day month, automatically adjusting the month and day via a cam and lever. Parameters such as the date and month can be independently set without tools, eliminating the tedious adjustment of traditional perpetual calendars.
Dual Chronograph System: The LM Sequential EVO features a twin-column-wheel chronograph with a "Twin Verter" binary switch, enabling five modes: independent, split, and cumulative timing. The power switching between the gear trains is accurate to within 0.1 second.
III. Balance Wheel Manufacturing and Adjustment
As the "heart" of a mechanical watch, the balance wheel's manufacturing and adjustment embody MB&F's ultimate pursuit of perfection:
Precision Machining of the Balance Wheel
Materials and Construction: The LM SE's 14mm balance wheel is crafted from beryllium bronze, with hand-chamfered and mirror-polished surfaces. Its edges are engraved with traditional adjustment screws, allowing for precise adjustment of the moment of inertia. luxury fake watches
Balancing and Adjustment: The watchmaker balances the balance wheel at least twice: first by scraping metal to adjust the mass distribution, and then by dynamically balancing with weighted screws to ensure that the amplitude deviation of the balance wheel at different positions is less than 5°.
Coordinated Control of the Dual Balance Wheel System
The LM No. 2's two 11mm balance wheels are individually calibrated to a synchronized frequency of 2.5Hz (18,000 vibrations/hour), and then their rates are averaged by a planetary differential gear set. The gear tooth profile accuracy must be controlled within ±2μm to avoid timing errors caused by transmission backlash.
IV. Hand-crafted Finishes and Artistic Presentation
MB&F views its movements as wearable mechanical works of art, imbuing them with soul through hand-crafted finishing:
Traditional Decorative Techniques
Côtes de Genève: Radiating patterns are hand-lathe-edged onto the bridges, with depth and spacing tolerances of less than 0.01mm. The refracted light creates a fluid effect of light and shadow.
Bevel Polishing: All metal edges are hand-beveled to a precise 45° angle and then polished to a mirror finish with a deerskin wheel, creating a silky smooth finish.
Hand-engraving: The balance cock of the LM Perpetual Longhorn is engraved with the brand logo and limited edition number. Each incision is just 0.1mm thick and requires the use of a magnifying glass.
Innovative Decorative Techniques
The LM SE EVO movement features a "blackening" treatment, a chemical coating that gives the steel components a dark grey hue. This creates a striking contrast of cool and warm tones with the rose gold balance bridge, creating a striking visual impact. Some limited editions feature hand-painted enamel dials, such as the LM Perpetual EVO's blue sunray-patterned dial, which requires more than three firings at 800°C. fake watches on sale
V. Limited Production and Quality Control
MB&F adheres to the principle of "slow and steady production," and each watch undergoes a rigorous manufacturing process:
The Artistic Value of Limited Editions
Series watches are typically limited to 20-33 pieces, such as the LM Perpetual Longhorn, of which only 20 were produced. Each watch is fully assembled by a single watchmaker, taking three to six months. For example, the 99 movements in the Bvlgari x MB&F Serpenti collaboration took over a year to complete, with each watchmaker assembling only six to eight pieces per month.
Multi-Dimensional Quality Control
Dynamic Testing: The movement is subjected to seven days of operation at a constant temperature (23±1°C). The timekeeping error in six positions is recorded, with the final accuracy controlled to within ±10 seconds per day.
Waterproofing: The EVO case has passed an 80-meter water pressure test, and a double O-ring seal ensures a tight seal between the sapphire crystal and the case.
Appearance Quality Inspection: Each watch undergoes 12 manual quality inspections, including the consistency of bridge chamfers and the uniformity of the luminescent coating on the hands. Any substandard step will result in rework.
Conclusion
The watchmaking craftsmanship of the MB&F Legacy Machine series is a perfect fusion of traditional watchmaking techniques and contemporary engineering. From the groundbreaking design of the split escapement to the delicate hand-engraving; from the precise adjustment of the double balance wheel system to the meticulous control of the limited production run, every detail demonstrates MB&F's unwavering commitment to "mechanics as art." As the suspended balance wheel of the LM Split Escapement symbolizes—MB&F consistently breaks the mold in watchmaking, transforming the flow of time into a visual and mechanical feast. https://www.proreviewwatch.co
