SARPANEVA KORONA K3 RED MOON

The red hued harvest Moon is something typical for Europe during this period of the year, and with the fall just having started here in Europe, and Halloween only a few weeks away, it was time for a new KORONA wristwatch to join the collection.

This new model, the KORONA K3 RED MOON differs from all the other Sarpaneva models currently available, in that it sports a black DLC treated case combined with an 18-carat red gold moonphase indication, marking the first entrance of the use of red gold within the Sarpaneva collection in a most striking and dramatic combination.

Creating the two deep hued, 18-carat red gold Moonphase discs for the KORONA K3 RED MOON itself is also a complicated task. The first dilemma concerns the dimensions, as the face is only 0.4mm thick yet has four levels of elevation. The first step requires creating a drawing six times the actual size, followed by cutting a rough model from plate stock, one piece corresponding to each level of elevation of the oversized model.

These parts are then fixed together to form the model plate for the pantograph, which will mill the shapes into a small piece of copper the actual size of the Moonphase indicator. This copper version, which will serve later as an electrode, is then cleaned up and fine-tuned by a master engraver before the contours are electro etched 0.4mm deep into a steel pressing block, thus creating a negative image of the face.

Last, the eyes are modeled by hand into the negative image and the whole is finished by a master engraver and diamond polished before undergoing hardening. This is followed by yet another polishing. Only now can the production of the Moonphase begin. The whole process from drawing to finished Moon takes a specialist company, also located in Finland, about two weeks to complete.
