Till now, all the watches were Haute Horlogerie Tourbillons, but at the beginning of 2017, AkriviA released the AK-06, the first watch without a tourbillon but with a sum of fantastic finishes.
They explained much better different steps of the watch creation: “Looking closely at the movement, you will see that the anglage created on the edges of all parts is rounded in what is called a bombé cross section, in opposition to the standard and fully or partially machine created anglage used today throughout Switzerland at large manufactures. This technique of rounded edges is much more time consuming to produce and cannot be prepared in advance by the use of machines. Starting with the basic flat piece of material with 90∘ angled edges, one of the first steps is to create a rounded edge by filing the edges into shape in several steps, which perfectly follows the edges equidistantly into every curve and corner. Furthermore, all sinks for the jewels also have a bowl shaped cross section, directly complementing this bombé effect of the rounded anglage This is followed by multiple steps of further finishing and polishing with a series of special wooden sticks covered in abrasive material as well as the natural wood itself. From the raw parts to finally finished parts, here is a general overview of the steps required to create perfectly finished watch parts and movement:
- Primary quality control of each machined piece
- Preparation of upper and of lower sinks
- Grinding of movement underside and sides followed by filing
- Execution of Geneva stripes
- Anglage grinding of curved and straight parts
- Anglage filing of curved and straight parts, including edges
- Anglage polishing of all filed edges in several steps
- Polishing of sinks
- Black polish surface polishing where required
Finally, for the highest gloss, a stick of the Gentian plant is used. This plant grows freely in the mountainsides of the valley and has been used for centuries in such work. The softer, inner layer of the wood is used on its own without additives in order to achieve an extremely high gloss finish. Such finishing is absolutely impossible to achieve with the standard use of electric tools or via CNC machining.” – AkriviA Website.
