View on Isotope’s site ↗Available Now: Chronograph Moonshot Thunderclap A storm captured in titanium . The first Isotope chronograph with a telemeter scale , limited to just 30 pieces . The Isotope Moonshot Chronograph Thunderclap captures the drama of a storm in mechanical form. Limited to just 30 pieces worldwide , this special edition introduces a striking new visual direction to the Moonshot platform and marks a milestone for the brand: the first Isotope chronograph to feature a telemeter scale . Developed in collaboration with Matt Smith-Johnson, known as Teenage Grandpa , Thunderclap combines proven Moonshot architecture with a bold new aesthetic language . A Collaboration with Teenage Grandpa The Moonshot Chronograph Thunderclap was created together with artist and designer Matt Smith-Johnson (Teenage Grandpa) , whose fearless visual style and instinct for the unexpected made him a natural partner for reinterpreting the Moonshot. “The first time I met Matt, I was immediately struck by his energy, sharp mind, and design originality. He had a genuine connection with the Moonshot, which led me to invite him to create his own interpretation of it. The result is bold and unexpected, a version that could only come from the mind of Teenage Grandpa.” — José Miranda, Co-Founder, Isotope Watches The result is a Moonshot that feels sharper and more expressive , while remaining faithful to the architecture collectors already appreciate . A Storm in Grey and Purple Thunderclap retains the full technical platform of the Moonshot while introducing a new visual language. The case is crafted from sandblasted Grade 5 titanium , presented without DLC coating so the metal’s natural character remains visible. The dial creates a striking interplay of texture and colour: • Grey embossed dimple dial , evoking charged storm clouds • Metallic purple Moondisc sub-dials that shimmer as light moves across them • Purple chronograph pushers delivering a vivid flash of colour on the case flank The Thunderclap is Industrial at first glance . Electric on closer inspection. Introducing the Telemeter Scale The Moonshot Chronograph Thunderclap introduces the first telemeter scale ever used on an Isotope watch. Historically , telemeters were used to measure the distance between a visible event and the sound it produces . By starting the chronograph when lightning appears and stopping it when thunder is heard, the scale indicates how far away the storm is. A scale born from science , speed , and instinct . Perfectly suited to a watch called Thunderclap . Proven Moonshot Architecture Thunderclap maintains everything that defines the Moonshot platform: • Identical Moonshot case architecture • The same chronograph movement configuration • 100m water resistance • Meticulous finishing throughout Everything that defines the Moonshot remains intact. Only the interpretation is new. Limited edition, available now for immediate shipping in very limited numbers.
