In automatic watches, a bidirectional micro-rotor converts kinetic energy – motion from the wearer’s arm – into potential energy for the mainspring, no matter the direction the micro-rotor is turning in. It is this efficiency that appealed to Romain Gauthier when he designed Insight Micro-Rotor. This should come as little surprise: Gauthier is a qualified constructor of precision machinery who brings, among many qualities, an engineer’s approach to his designs for the brand’s in-house movements.

Twenty years ago, it started with a kick. A young watchmaker stood beside his stone dead motorcycle with a kick-start pinion in his hand. The bike refused to start but he refused to give up. He never gave up. That kick-start pinion was given a new lease of life as the very first Sarpaneva watch.

Fueled by the Finnish madness, he has since created exceptional watches for every one of you who dares to ride alone, from dusk till dawn, through the darkest nights.

You are the brave. You are the star. The Korona K0 Daredevil is a tribute to you.

Following the phenomenal success of the luminous Northern Lights and Seasons, the Korona K0 Daredevil ensures that the glow must go on. The dial features a vibrant afterglow by RC Tritec, AG’s LumiCast, made of Swiss Super-LumiNova®.

turns the A11B (Basis) into the A11S (jumping second). And its installation in the slim 38.5 mm case means Felix now has a twin brother named Erwin. Erwin is at least as handsome and just as big as its older twin, although slightly more plump. Its movement with the jumping second is still a slim 5.7 mm and its 9 mm case fits comfortably beneath even snug-fitting sleeve cuffs. This is made possible by the new design of the jumping second that is much flatter in comparison to earlier hand-wound watch movements with this little complication.

The Grönefeld Remontoire features an eight seconds constant force mechanism, ensuring the force serving the balance wheel does not wane. From the mainspring being fully wound to the last minute of the 36 hours of power reserve, when the stop works intervenes, the force never fluctuates. The result is that the amplitude and rate remain …

The latest (Four) Seasons features four distinct different aesthetics, each with a unique luminous back dial by Black Badger (of Sweden). Each watch starts with the 46mm Stainless Steel Korona K0 diver case, featuring the iconic Sarpaneva Moon-face embossed on the caseback!
