From Harold Pinchbeck

A Playful Sum of Style Precision, Playfulness, and a Luminous Twist The Sigma is where practicality meets personality. Named after the Greek letter Σ (Sigma), a symbol of sum and completeness, it brings together the elements that make everyday wear delightful: colour, function, and craftsmanship. Beyond its mathematical roots, “Sigma” has become a mark of precision, sophistication, and innovation, a subtle nod to something distinctive and elevated. That spirit is reflected in the Sigma’s luminous markers and hands, which glow in the dark, giving this small 36mm watch a signature personality that is both playful and uniquely recognisable. The teal blue dial with soft peach markers adds a cheerful touch, while the off-white seconds hand provides a quiet contrast. Paired with a Tanner Bates conker leather strap, the Sigma blends Pinchbeck’s British heritage with contemporary design, making it a practical daytime companion and a collectible for the long term. Designed as a partner to the Novum, Sigma will grow with the collection, each edition adding a new color story. Lighthearted, thoughtful, and unmistakably Pinchbeck, the Sigma proves that everyday elegance can be joyful and luminous in its own way.
