Isotope Moonshot Chronograph Thunderclap

Isotope introduces the Moonshot Chronograph “Thunderclap”. A limited edition of 30 pieces featuring the brand’s first telemeter scale. 

London, UK — Isotope Watches proudly unveils the Moonshot Chronograph Thunderclap, a bold new interpretation of its signature chronograph platform. Limited to just 30 pieces worldwide, Thunderclap combines proven Moonshot architecture with a striking new aesthetic direction and a historic first for the brand: the introduction of a telemeter scale.

A sudden flash. A rolling echo. A bolt of color against a brooding sky. Thunderclap captures that energy in mechanical form.

This special edition marks a collaboration with Matt, known to many as Teenage Grandpa, whose fearless visual language and instinct for the unexpected make him a natural partner in 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

The result is Thunderclap: familiar in architecture, entirely new in attitude.

A Storm in Grey and Purple

At its core, Thunderclap retains the full technical specification of the original Moonshot, while presenting a distinctly new visual identity.

The case is crafted from sandblasted Grade 5 titanium and presented without a DLC coating, allowing the metal's natural character to take center stage. Clean, purposeful, and honest.

The dial introduces a dramatic interplay of texture and color:

• A grey embossed dimple dial, evoking charged storm clouds

• Metallic purple Moondisc sub-dials, shimmering with shifting light

• Matching purple chronograph pushers, delivering a vivid jolt of color at the case flank

The effect is industrial yet electric, understated at first glance, explosive on closer inspection.

Introducing the Telemeter Scale

Thunderclap is a milestone for Isotope as the brand’s first chronograph to feature a telemeter scale.

Historically used to measure the distance between a visible event and the sound it produces, such as lightning and thunder, the telemeter allows the wearer to calculate how far away a storm is by timing the interval between the flash and the sound. A scale born from science, speed, and instinct, it is perfectly suited to a watch named Thunderclap. Function meets storytelling. Precision meets poetry.

Proven Moonshot Architecture

Thunderclap maintains all the core specifications and technical performance that define the Moonshot platform:

• Identical case dimensions and construction

• The same chronograph movement architecture

• 100m water resistance

• Meticulous finishing throughout

Everything that defines the Moonshot remains intact; only the visual language has shifted.

Pricing & Configuration

The Moonshot Thunderclap is available in two configurations:

• £2,400 Fitted to a purple FKM rubber strap

• £2,720 Supplied with both rubber strap and matching titanium bracelet

The titanium bracelet will also be offered separately, with dedicated imagery for customers who wish to purchase it independently. With production strictly limited to 30 pieces, availability is expected to be extremely limited.
