Strap for Chyros Balancier Visible - silvered / black leather strap (Croco)

The lug width of the Limes Chyros U6017-LA2.5 is precisely 20 millimetres. This dimension represents a deliberate engineering choice by Limes, calibrated to maintain correct proportions between the 43mm case and the wearer's wrist. To verify compatibility with any aftermarket strap, measure the space between the lugs using a digital calliper: the result must correspond to exactly 20mm.

For the Limes Chyros U6017-LA2.5 we recommend three primary solutions: alligator in medium brown for maximum elegance, as its regular texture enhances the case's brushed finish; English calf leather with vegetable tanning for those who appreciate natural leather patina and ageing; ballistic nylon NATO strap for those who prefer functional aesthetics without sacrificing visual balance. Your choice depends on primary use: formal, daily wear, or instrumental.

Strap replacement is performed through the spring bars (passants). Position the watch on a softpad, identify the two spring bars at the ends of each lug, use a spring bar tool to depress the small button beneath each bar, then gently extract the previous strap. Insert the new strap by aligning the holes with the lugs, verify that the spring bars are correctly positioned and locked. The process requires precision but no specialised tools beyond a spring bar tool.

Yes, but it is essential that the strap is specifically dimensioned for a 20mm lug width. Not all aftermarket straps are available in this size: the market standard gravitates around 18, 20 and 22mm. Always verify the manufacturer's specifications and measure your Chyros U6017-LA2.5 lug width to exclude purchasing errors. milanostraps.it offers artisanal straps specifically crafted for this dimension.

Leather strap durability depends on material and usage. Vegetable-tanned calf resists an average 3–5 years under daily wear conditions; alligator, due to skin robustness, can reach 5–7 years. Determining factors are exposure to moisture, body perspiration and periodic maintenance (gentle cleaning, conditioning with specific creams). A ballistic nylon NATO offers superior longevity, up to 10+ years, although it requires less maintenance attention. Periodic replacement remains advisable to prevent failures during wear.
