Formex Essence 39mm Automatic COSC Gets Generational Upgrade for 2026
Swiss Watch Brand Formex Updates Its Best-Selling Chronometer
Formex has announced a generational update to its best-selling model, the Essence 39mm Automatic COSC. The Swiss independent brand, which relaunched under CEO Raphael Granito in 2016, has refined its flagship chronometer watch with several key upgrades while maintaining the proven design that has made it a favorite among collectors since its 2018 debut.
The updated Essence 39mm features a screw-down crown, an improved clasp extension system, and an upgraded movement with longer power reserve – all while remaining COSC-certified as a chronometer.
Key Upgrades for 2026
The new generation of the Formex Essence 39mm introduces meaningful improvements that enhance both functionality and user experience:
| Specification | Previous Generation | 2026 Update |
|---|---|---|
| Crown Design | Standard | Screw-down |
| Clasp Extension | Basic adjustment | 6mm total adjustment |
| Movement | Sellita SW200-1 | Sellita SW200-2 Power+ |
| Power Reserve | 38 hours | 65 hours |
Movement Upgrades
The heart of the update is the transition from the Sellita SW200-1 to the SW200-2 Power+. While sharing the same basic architecture, the new movement incorporates numerous reworked components designed to increase efficiency. The result is a significantly longer power reserve of 65 hours – nearly double the previous generation's capacity.
Like its predecessor, the SW200-2 Power+ maintains COSC chronometer certification, ensuring accuracy within the -4/+6 seconds per day standard. The movement operates at a frequency of 4Hz (28,800 vibrations per hour), providing smooth hand motion and reliable timekeeping.
Design and Features
The Essence 39mm continues to feature Formex's patented Case Suspension System, which absorbs shocks and enhances comfort on the wrist. The case measures 39mm in diameter by 10.5mm thick, with a lug-to-lug distance of 45.5mm and 20mm lug width.
At launch, three dial options are available:
- Blue (ref. 0339.1.6631) – Formex's signature shade
- Alpine White (ref. 0339.1.6613)
- Radiant Bronze (ref. 0339.1.6681)
All models offer 100 meters of water resistance and feature flat sapphire crystals with anti-reflective coating on both sides.
Pricing and Availability
The Formex Essence 39mm Automatic COSC is available with multiple strap options. Pricing starts at $1,850 USD for models on nylon, leather, or rubber straps, with the stainless steel bracelet version priced at $1,980 USD. The watches are available immediately through authorized retailers and the Formex website.
