Strap for Chronoris Date / Black / Bracelet

The lug width is 19 millimetres, measured as the internal distance between the two lugs of the case. This technical specification is unique to this model and requires straps from specialist manufacturers or artisanal producers.

For a stainless steel chronograph of this proportion, we recommend vegetable-tanned gum-lined leather (water-resistant), alligator or shell cordovan for formal occasions, or technical nylon NATO for intensive sporting use. Choice depends on environment: urban (leather), active wrist (NATO).

The lugs use straight springbars without retention springs. Position a spring bar removal tool under the lug slot of the current strap, lift gently until the spring releases, remove the pin. Repeat on the opposite side, insert the springbar ends into the new strap and secure to the lugs.

No. The 19mm lug width does not accommodate 20mm straps without compromising fit on the lugs. Forcing a wider strap risks degrading the lug finish and creating undesirable mechanical play.

A quality vegetable-tanned leather strap, subject to moderate daily use, maintains elasticity and patina for 3-4 years. Sun exposure and humidity accelerate ageing. Periodic maintenance with nutritive creams extends useful life and develops distinguished patina.
