Strap for Chyros Automatic - Black / brown leather strap (Croco)

The lug width of the Limes Chyros U6017-LA1.4 is 20 mm. This measurement refers to the internal distance between the two spring bar attachment points on the case lugs. To verify, use a digital calliper positioned between the inner edges of the lugs. An accurate measurement ensures complete compatibility with quality 20 mm straps.

The choice depends on usage and personal aesthetic preference. For sporting elegance, we recommend Mississippi alligator in deep blue or shell cordovan with vegetable tanning in dark brown. For nautical use, a NATO strap in Cordura canvas, charcoal grey, is ideal. For technical or damp environments, black FKM rubber with stainless steel deployante offers maximum practicality. The brushed finish of the Chyros case pairs particularly well with dark tones and materials with subtle texture.

The Chyros U6017-LA1.4 uses a standard spring bar system. To change the strap: 1) Obtain a spring bar tool; 2) Insert the flat tip beneath one of the bars; 3) Push gently downward until the pin releases from the lug seat; 4) Repeat on the opposite side; 5) Thread the new strap under the lugs and secure with the spring bars. Verify that your replacement strap is designed for a 20 mm lug width before proceeding.

Yes, provided the strap is specifically constructed for a 20 mm lug width. Quality artisanal straps (such as those from Milano Straps) are crafted with rigorous manufacturing tolerances: the internal passants measure 18–19.5 mm, allowing precise fit on the lug. Avoid economical, mass-produced straps, as approximate tolerances may compromise the aesthetic integrity and functionality of your watch.

A natural leather strap (alligator, shell cordovan, calf) typically lasts 3–10+ years depending on frequency of wear, humidity exposure, and maintenance. Vegetable-tanned leather develops character with age and lasts longer than industrial alternatives. With periodic care (gentle cleaning, light conditioning), a shell cordovan or alligator strap can easily exceed seven years. Italian calf leather straps typically reach 4–6 years of daily use.
