Its tourbillon movement featured three parallel bridges, under which the barrel, center wheel and tourbillon were aligned. On this innovative concept, the tourbillon served not merely being a technical and funcational component, but because a design element as well.

The "Breguet" Arabic numerals painted for the silvered dial, and also the blued steel leaf-shaped hands, tend to be clear references to a time when only pocket replica watches existed. The clean lines of their 40-millimeter case disguise an advanced design and production process. Its curvature and lugs have been carefully fashioned to sit down perfectly within the wrist. The case-back, closed by 6 screws, is hand-engraved to evoke the domes of Girard-Perregaux's tourbillons dating in the 1800s. Each bit bears its own individual number, also engraved yourself commensurate with the Brand's tradition.True houses a Girard-Perregaux 9610 movement comprising 224 components, the refined decoration and architecture which can also be inspired by 19th century pocket tourbillons.The tourbillon bridge on the new Girard-Perregaux 1966 Tourbillon has an unusual shape tag heuer watches singapore : called "bassine", both the arms of the bridge are rounded off. The rounding off process consists of filing the ends with the arms to ensure they are perfectly uniform, offering them a semi-cylindrical shape while retaining the demarcation with the center as well as the heels cheap replica watches . To finish the operation, the craftsmen use stones, buffs , boxwood and diamond pastes to smooth them to a wonderfully rounded finish. The slightest imperfection is usually immediately detected because of the human eye alone. This craftsmanship necessitates the highest volume of dexterity and concentration.The fragile tourbillon also demands extreme attention to detail: incredible dexterity is needed to assemble its 72 components, all of which match a diameter of just one centimeter. It weighs 0.3 gram - about the same to be a swan's feather. Accompanying it's really a self-winding system patented with the Manufacture: a small-diameter platinum oscillating weight is housed in the space below and around the barrel.
