The Heritage

The Ressence Type 1 Champagne is a 42mm titanium case watch with a 20mm lug width, featuring the manual-wind ROCS1.2 caliber visible through an opalescent dial. The minimalist design displays hours, minutes, small seconds, and day indication, embodying the Belgian watchmaker's philosophy of functional essentiality over aesthetic ornamentation. The titanium case offers superior lightness and mechanical resistance compared to steel.

FAQ

What is the lug width of the Ressence Type 1 Type 1CH?

The Ressence Type 1CH requires a 20mm lug width. This dimension is precise and does not tolerate significant variations: always verify that your current strap falls between 19.5mm and 20.5mm to ensure correct fit without mechanical stress on the case lugs.

Which type of strap is best suited for the Type 1CH?

For the Type 1CH we recommend authentic alligator in neutral tones (black, cognac, anthracite grey) to amplify the minimalist aesthetic of the titanium case. Vegetable-tanned calf leather is excellent for those seeking evolutionary patina over time. Natural cotton NATO or rubber are options for those prioritising extreme functionality and aesthetic universality.

How do I change the strap on the Type 1CH?

Use a spring bar tool with appropriate thickness for 20mm lugs. Position the strap end into the lugs by carefully placing the spring bar tool to avoid scratches on the satin-finished titanium. The Type 1CH does not feature a deployant clasp, so changing straps is straightforward but requires manual precision.

Can I use an aftermarket compatible strap on the Type 1CH?

Yes, any quality 20mm strap (alligator, structured leather, NATO, rubber) is mechanically compatible with the Type 1CH. The only criterion is aesthetic conformity: the strap must respect the constructive minimalism of the watch. Consult our collection of 20mm straps for verified solutions.

What is the lifespan of a leather strap on the Type 1CH?

A high-quality alligator or calf strap lasts 4–6 years with regular wear if properly maintained (monthly cleaning, semi-annual water-repellent treatment). Vegetable tanning develops natural patina over time, improving aesthetics. Environmental humidity, frequency of wear and sun exposure significantly influence longevity.
