Schwarz Etienne began with a vertical combination technique a couple of years prior, going similarly as delivering hairsprings in-house, with their sister company E2O advancements ( read our new presentation article about the brand here ). This elaborate deep items’ advancement and a procedure dependent on a modular way to deal with development; a group of mechanical developments was made and developed into various variants. Today, we investigate the fascinating La Chaux-de-Fonds Tourbillon Petite Seconde Retrograde, which was introduced during Baselworld 2017.
The Schwarz Etienne La Chaux-de-fonds Tourbillon Petite Seconde Retrograde or PSR (for retrograde little second) is the latest cycle of a groups of developments started with the introduction of the MSE (Manual Schwarz Etienne) type in 2013, a decent 13”’ ¼ twin barrel development with 4 days of force hold. It was trailed by the ASE (Automatic Schwarz Etienne), the ISE (Irreversible Schwarz Etienne) and the TSE (Tourbillon Schwarz Etienne).
The TSE type is a one-minute tourbillon development with its miniature rotor on the dial side. It currently consolidates a retrograde little second, coordinated in a truly unique way, as its component is fabricated straightforwardly regarding the Tourbillon. A snail cam (colimaçon for those anxious to construct their French watchmaking vocabulary) is mounted on the tourbillon arbor. A wrench gear is laying on this cam while the framework is tensioned with a spring made with E2O Innovations. The instrument accordingly takes into consideration the little seconds hand to progress along a curve and afterward suddenly hop back to recommence at the beginning point.
Because the cam is molded with a continually expanding width, there is little unsettling influence in the best approach to Tourbillon is running, albeit the retrograde seconds is mounted straightforwardly on its arbor. In this regard, Schwarz Etienne reports that the amplitude misfortune is under 10%, which permits the tourbillon to work efficiently.
The movement of the tourbillon and of the retrograde seconds is attractive and this artful dance is completed by the oscillation of a cool bi-directional miniature rotor. The development uncovers its inward functions in complete straightforwardness. The play of development, volumes, differentiating materials and tones functions admirably and adds a ton of visual depth. The development includes a dim get done with sandblasting on the fundamental plate, Geneva stripes and hand-chamfering. It runs at 3 Hz, for a force hold of 72 hours (3 days).
The Schwarz Etienne La Chaux-de-fonds Tourbillon Petite Seconde Retrograde is available in two variants. Green aventurine or dim hematite specularite (fine stones) are utilized to make the little seconds pointer and the topsy turvy hours and minutes dial. 44mm in breadth, the round case is created from steel or pink gold. Its back is engraved with cog wheels and highlights an opening on the Tourbillon cage.
The Schwarz Etienne La Chaux-de-fonds Tourbillon Petite Seconde Retrograde is worn on a subjective croc tie with green or dim crocodile lining, coordinating the shade of the dial which is a pleasant touch. It is shut with a collapsing clasp. For more data, visit www.schwarz-etienne.com .
