The Type 1 Type 1S, seen from the bench

The Type 1 represents Ressence's debut model, characterized by the brand's patented orbital display system. It mounts the ROCS 1.2 caliber that manages hours, minutes, small seconds, and day indication through overlapping rotating discs. The model features 20mm lugs and a dial without traditional hands.

Frequently asked questions

What is the exact lug width of the Ressence Type 1S?

The Ressence Type 1S features a 20mm lug width. This dimension is measured perpendicularly between the two integrated lugs, from the internal point of one bar to the other. A correctly dimensioned 20mm strap maintains the proportional harmony that Ressence engineered for this model.

Which strap is most suitable for the Type 1S?

For the Type 1S, we recommend an alligator strap with pronounced grain or vegetable-tanned calf leather. These materials create tactile contrast with the titanium case without visually competing with the transparency of the hydrological movement. Structured alligator enhances the case's mineral quality; aged calf develops patina over time, interpreting the watch as an evolving instrument.

How do I change the strap on a Ressence Type 1S?

The Type 1S uses standard 20mm lugs. Carefully disengage the original bracelet by gently removing the suspension bars from the lugs. Insert the new strap, aligning it perpendicularly to ensure bars remain parallel. Do not apply excessive force: the lugs are calibrated for straps not exceeding 4mm thickness. If the strap does not slide smoothly, verify alignment rather than forcing it.

Can I use an aftermarket strap on a Ressence Type 1S?

Yes, any strap with a 20mm lug width is compatible with the Type 1S, provided thickness does not exceed 4-4.5mm. We recommend avoiding synthetic leather or rigid materials, which compromise the mechanical precision sensation characterising this watch. Handcrafted natural leather straps maintain aesthetic and functional coherence with the timepiece.

How long does a leather strap last on the Type 1S?

A quality leather strap (alligator or calf) lasts 3-5 years with daily use, depending on environment and maintenance. Vegetable-tanned leather develops patina and increases in resistance with ageing. The Type 1S, being a technical instrument rather than formal jewellery, requires straps that evolve parallel to the case: replacement represents a moment of conscious renewal, not unexpected wear.
