This watch is the successor to the 2008 Big Pilot’s Watch Markus Bühler Special Edition. This time, the watch’s flying minute tourbillon set at 6 o’clock is uniquely integrated into the aircraft turbine design. This is a huge challenge at both the design and manufacturing levels. It features a polished platinum case with a shiny black dial and a black cordovan leather strap. The watch is equipped with the 82905 movement independently developed by IWC. Its parts have been treated with a special process and appear black. Through the sapphire transparent glass case back, the exquisite details of the movement can be seen at a glance.
In the IWC Big Pilot’s Watch fake series, there may be no other work comparable to this one. This piece was inspired by a unique piece created by Markus Bühler while participating in a competition during his final year of apprenticeship at IWC. Its distinctive feature is the aircraft turbine equipped on the small seconds hand on the dial, which has a unique and eye-catching design.
After fifteen years of development, IWC has reinterpreted this masterpiece so that it is still charming and unique. The newly released Big Pilot’s Watch 43 Tourbillon Markus Bühler Special Edition also retains a turbine design on the dial, but the difference this time is that this watch’s characteristic aircraft turbine is combined with a flying minute tourbillon and is placed at 6 O’clock position.
Small turbine, big challenge
In the tourbillon structure, the balance wheel and escapement are placed in a small cage that rotates around its own axis once per minute. Since the greater the mass and inertia of the entire device, the higher the power required. Therefore, weight reduction became a core goal of tourbillon construction. Based on this concept, the turbine is made of lightweight titanium alloy. Due to their complex geometry and small size, each blade requires hours of milling. Moreover, each processed paddle needs to be polished and finely ground by hand to achieve the ultimate precision and beauty.
In order to avoid the turbine adding extra weight to the mechanism, Bühler cleverly used the turbine itself as the upper part of the tourbillon cage, replacing the traditional regulator. This not only makes the turbine a highlight on the dial, but also gives it an actual technical function.
The hairspring is fixed to the bottom of a certain blade, and the watchmaker can adjust the zero position of the balance wheel by turning the turbine. This advanced tourbillon consists of 56 parts and has a total weight of only 0.663 grams. In addition, the pallet fork and escapement wheel are treated with DiamondShell® technology. This special coating can reduce friction and improve the smooth transmission of the movement’s kinetic energy.
Precious platinum case and fine surface modification
The case and crown of this fake 43 mm large pilot watch are made of precious platinum. Platinum is prized in the watch and jewelry industry for its rarity, purity and noble qualities. The case of this watch is finely polished by hand, and the bezel and lugs are polished, which makes the platinum shine even more dazzling and gives the entire watch a refined, elegant and sophisticated look.
The smooth black dial is printed with white numerals, and these hour markers are filled with Super-LumiNova® to ensure legibility in dim environments. The inside of the matching black cordovan leather (Cordoba leather) strap is also printed with Markus Bühler’s autograph. This design detail makes the overall shape more smooth and natural.
This large fake pilot’s watch 43 is equipped with the 82905 movement independently developed by IWC. Its automatic winding system, the Pellaton system, composed of solid ceramic components, can provide the mainspring with a power reserve of up to 80 hours. Through the sapphire transparent glass back, you can clearly see the plywood, bridge and oscillating weight treated with black PVD coating. The parts are also laser engraved and finally rhodium plated in the engraved areas, adding to the aesthetic appeal of the visual effect.
