Crafted by Swiss watch maker Rexhep Rexhepi, the AkriviA Tourbillon Regulator successfully alliances minimalist exteriors with an haute horlogerie complication. The broad lugs are chamfered in a manner reflecting the bevelling on the calibre; the grey dial features a “polished-matt” finish that is both vintage and innovative.
While it recalls the sandblasted bridges of pocket watches, the AkriviA “polished-matt” effect differs from habitual sandblasting in terms of its means of application: the crushed stone is mixed with vegetable oil and applied using a new handcrafted technique.
The only fanciful aspect of the dial is the regulator-type arrangement of its indication, with the hours counter at 12 o’clock, the central axis bearing the minutes hand only, and the seconds hand fixed to the tourbillon at 6 o’clock.
The latter is indeed the only clue to the exceptional nature of this timepiece: the austerity of the exterior finishes highlights the wealth of finishes lavished on the movement. This simple dial opening reveals a bridge featuring eight inward angles and which bears the escapement block.
The latter is composed of a 13.7mm carriage revolving in one minute and housing a Breguet balance-spring connected to the “AkriviA” balance wheel oscillating at the rate of 21,600 vibrations per hour. The 100 hours of autonomy is supplied by a single barrel.
The 11.6mm “AkriviA” balance wheel features four spokes forming a “Quadriskell”, with four fine-adjustment inertia-blocks at the end of each. The purpose of putting in place these various devices is to have the Tourbillon Regulator certified by two institutions: the COSC and the Poinçon de Genève.
With this in mind, the elaborate nature of the movement finishes is the exact opposite of the outward austerity: the movement features 50 inward angles and is entirely decorated on both visible and hidden parts: domed chamfering, handcrafted Côtes de Genève, circular graining, straight graining. This AK-04 calibre was both developed and finished entirely by Rexhep Rexhepi and his team at AkriviA.
One of its major characteristics is its complete symmetry: it nobly comprises two third wheels so as to ensure optimal visual balance. This rare construction, combined with a high level of finishing, reflects Rexhep Rexhepi’s perfectionism.
