Additional information

A high-end construction, the micro-rotor permits the integration of an ultra-compact automatic winding mechanism. For maximum efficiency, and despite its reduced diameter, winding is bidirectional. This elegant solution ensures the caliber can be admired in all its splendour. The oscillations of the micro-rotor on the dial side add dynamism to the design

Entirely manufactured in-house, including the hairspring, the balance wheel features an exclusive design feature. On balancing it draws the brand’s SE initials.

Schwarz Etienne leather straps are produced by saddlers from the finest leathers. Each strap is both handmade and hand-stitched. An elegant and original signature, they are lined in vibrant colours, just like the finest suits.

The La Chaux-de-Fonds Tourbillon PSR is enhanced with fine stones adding colour and a sense of depth to its face. The off-centre hours and minutes dial and the retrograde seconds’ indicator are fashioned out of green aventurine, anthracite hematite specularite, lapis lazuli or blue opal. Their delicate manufacturing requires extreme care, the cutting and the finishing of these stones demanding skill, precision and savoir-faire.

The flying tourbillon is a skewed construction with no bridge holding the regulator. This provides an unhindered view of its mechanical processes. Entirely manufactured in-house, including the balance and hairspring, it performs a rotation per minute and oscillates at 21’600 vibrations per hour

The La Chaux-de-Fonds Tourbillon case back is engraved with a gears motif. A small circular opening around the tourbillon reveals a captivating ballet from multiple angles, lending light to these exceptional mechanics.
