Formex Essence 39 Automatic Chronometer Stone Dial Watch Series

The Formex Essence ThirtyNine Automatic Chronometer Stone Dial Series represents a sophisticated fusion of high-precision Swiss engineering and natural artistry. This collection elevates the versatile 39mm Essence silhouette with dials crafted from rare, natural materials—ensuring that every individual timepiece possesses a unique visual signature. Despite their elegant appearance, these watches remain true to Formex’s tool-watch heritage, featuring the brand's patented Case Suspension System to provide superior shock protection and a adaptive, comfortable fit on the wrist.

The collection’s 39mm case is meticulously finished with a combination of satin-brushed surfaces and mirror-polished bevels, achieving a slim 10mm profile that transitions effortlessly from casual to formal settings. Each variant offers a distinct character depending on the stone used. To maintain ultimate clarity, the dials are protected by a scratch-resistant sapphire crystal with a specialized anti-reflective treatment.

At the heart of the series is the Swiss-made Sellita SW200-1 movement, regulated to  "Chronometer" grade and officially certified by COSC. This high-performance caliber features a Glucydur balance wheel for stability and a custom-built skeletonized rotor with thermally blued screws, all visible through a transparent exhibition case back. Designed for practical luxury, the Essence ThirtyNine includes a tool-free quick-release system for swapping between a stainless steel bracelet with micro-extension and a variety of premium leather or rubber straps.
