This is a stainless-steel Sarpaneva Korona Seasons Edition KO-Summer. It includes a scalloped, sculptural stainless-steel case on a leather strap with a stainless-steel deployment clasp and a scratch resistant sapphire crystal with multi-layer anti-reflective coating. It has a stainless "piston" style screw down winding crown at 4 o'clock, a solid case back secured with 6 screws with a high-relief Sarpaneva "Man in the Moon" face, and it's engraved with "SARAPANEVA – DORONA KO SEASONS – SUMMER," and a serial number. The 46mm flourished hexagonal case, straight lugs, and flat scalloped bezel, are polished. The dial was a collaboration with the Black Badger Advanced Composites in Sweden and it's fully luminous with a completely open worked steel green sunray grid and trapezoidal hour markers. It has polished steel curved sword hour and minute hands and a green center sweep second hand with a skeletonized counterbalance. This Sarpaneva Korona KO Seasons-Summer edition has a mechanical automatic self-winding Soprod A10 movement with modifications by Sarpeneva. It's rhodium plated and protected by the "grid." It's constructed with 25 jewels, an anti-shock system, a monometallic balance, a self-compensating flat balance spring, and a skeletonized stainless-steel rotor with a white gold mass and another white gold moon face. The mechanism oscillates at a frequency of 28,800 vph (4Hz). The Sarpaneva Korona KO Seasons-Summer edition was designed by Stepan Sarpaneva and it was produced in 2016 in an extremely limited edition of only 20 examples worldwide
