The Formex Essence ThirtyNine distills the technical innovation and refined aesthetics of the original Essence into a more compact 39mm case — offering COSC-certified accuracy, crisp finishing, and daily versatility in a slim, lightweight package.

Its horizontally brushed dial features CNC-machined grooves, applied indices, and a beveled date window at 6 o’clock. The stainless steel case blends brushed surfaces with polished accents and integrates Formex’s patented suspension system, providing both comfort and shock resistance. A box-shaped sapphire crystal with anti-reflective coating ensures clarity from every angle, while the exhibition caseback reveals the decorated Swiss movement within.

Powering the Essence ThirtyNine is the Sellita SW200-1, a chronometer-certified automatic movement that delivers smooth 28,800 bph operation, hacking, hand-winding, and a 41-hour power reserve. The watch comes fitted with a stainless steel bracelet equipped with a tool-free micro-adjust clasp, making it a timepiece built to wear all day, every day — with no compromise.
