Strap for Chronographs San Fransisco / Stainless Steel / Creme

The Laco Chronographs 861585 features a lug width of 22mm. This measurement refers to the distance between the two pins that attach the strap to the watch case. It is essential to verify this specification before purchasing an aftermarket strap to ensure compatibility. You can check by measuring the distance between the case lugs with a ruler.

For the Laco Chronographs 861585, we recommend three solutions: alligator or calf leather in brown or chestnut tones for a classic aviator aesthetic; NATO strap in ballistic nylon (grey or black) for tactical versatility and water resistance; natural rubber for a contemporary and sporty interpretation. Your choice should depend on intended usage and wearing context. Vegetable-tanned leather ensures the most natural and compelling patina development over time.

Changing the strap on the Laco 861585 is a straightforward operation. Obtain a spring bar tool and, while holding the watch steady, insert the tool's tip into the small slot at the rear of the pin. Gently press to compress the internal spring and slide the pin outward. Repeat on the opposite side. To install the new strap, thread the pins through the watch case lugs and ensure they are fully seated.

Yes, aftermarket straps can be fitted without any issue, provided they are compatible with the 22mm lug width. The market offers a comprehensive range of straps in premium leather, NATO fabric, rubber, and specialised materials—all compatible with the 861585. Milano Straps curates a selection of 22mm straps tailored to this chronograph and customisable according to your aesthetic preferences.

A leather strap's longevity depends on material quality and usage frequency. A strap crafted from vegetable-tanned leather, such as those offered by Milano Straps, maintains structural integrity for 5–8 years with daily wear. The leather softens and develops a natural patina that increases aesthetic appeal over time. To extend its lifespan, avoid prolonged exposure to saltwater and direct sunlight, and occasionally apply dedicated leather conditioners. The underside (or riporto), which contacts the wrist, is the most wear-prone component and can be replaced independently of the main body.
