The Type 1 Type 1RG, seen from the bench

The Ressence Type 1 Rose Gold features a 42mm rose gold case housing the Ressence ROCS1.2 caliber movement. This model employs the proprietary Öilarium™ system, which fills the case with high-density synthetic oil to eliminate reflections and provide unobstructed dial visibility. The 20mm lug width is proportionally calculated to complement the case diameter and material choice.

Frequently asked questions

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

The Ressence Type 1RG is equipped with 20-millimetre lugs. This dimension is model-specific and derives from a calculated proportional relationship between the case diameter (42mm) and the strap's aesthetic support. Correct measurement is performed with a digital calliper, positioning the tips on the internal base of the lug whilst excluding the lateral wings.

Which strap type pairs best with the Type 1RG?

Alligator in smoke-brown or absolute black represents the most coherent solution with the Type 1RG's experimental ethos. The natural texture of the leather does not compete with the Öilarium™ transparency but rather emphasises it through tactile contrast. Alternatively, vegetable-tanned calf offers softness and irregular grain, whilst NATO fabric straps create stark tonal contrast with the rose gold, accentuating the chronometric character of the watch.

How do I change the strap on a Type 1RG?

The Type 1RG utilises fixed lugs with standard 20mm holes. To replace the strap, you will require a spring bar remover: insert the flat tip into the lower lug shoulder, gently lift the spring bar assembly until disengagement from its seat, then extract the worn strap. Reverse the procedure to install the new strap, verifying that the spring bar is correctly centred in the lug holes before release.

Can I use an aftermarket 20mm strap on the Ressence Type 1RG?

Yes. The Type 1RG is compatible with any quality strap manufactured to 20mm lug width specification. It is essential to verify that width measures exactly 20mm: undersized straps (19mm) will create undesired play, whilst oversized options (21mm) will generate friction and potential marking on the rose gold lugs. We recommend straps from specialist manufacturers to ensure finishing and construction coherent with the watch's calibre.

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

A premium leather strap (alligator, vegetable-tanned calf) maintains structural integrity for 3–5 years with regular wear. Longevity depends upon: frequency of use, exposure to moisture and direct sunlight, corporeal perspiration. The rose gold case of the Type 1RG does not stain leather straps as ferrous cases would, limiting the primary degradation factor. A well-maintained strap, periodically conditioned, may extend its useful life to 7 years. Rubber offers superior durability (8–10 years) but requires periodic cleaning to prevent surface haziness.
