Strap for Chronographs Havanna / Stainless Steel / Superluminova

The Laco Chronographs 861892 features a 22mm lug width. This dimension is fixed and allows you to match straps specifically constructed for this standard without adapters. To verify strap compatibility, measure the perpendicular distance between the spring bar shoulders on the case.

Genuine alligator leather with vegetable tanning is the premier choice: the regular cell texture and fine grain elevate the chronograph's instrumental aesthetic, whilst the natural patina develops a visible narrative over time. For those preferring a sportier aviator look, a cotton NATO strap in high density directly references the model's military origins. Structured calf leather represents an elegant compromise between practical durability and formal elegance.

The strap is replaced by unscrewing or extracting the pins (spring bars) from the case lugs using a dedicated spring bar tool. Position the tool beneath the pin gently, lift the old lug, and extract the pin in the opposite direction. Insert the new strap, aligning it with the lugs, then reinsert the pin horizontally until it clicks into place. Verify symmetrical positioning before wearing the watch.

Yes. The 22mm lug width is a consolidated standard, therefore quality artisanal straps constructed for this width will fit correctly to the case. Milano Straps offers a curated selection of 22mm straps built to rigorous technical specifications: alligator, leather, NATO, rubber. We recommend ensuring the strap does not exceed 4–5mm total thickness to guarantee smooth case closure.

Genuine alligator leather with vegetable tanning typically lasts 5–7 years with moderate daily wear. Longevity depends on factors such as moisture exposure, perspiration, temperature fluctuations and frequency of use. Structured calf tends to last 3–5 years, as the surface is more permeable. Leather should be protected from prolonged water submersion and extreme temperatures. Polishing the strap every 2–3 months with natural wax extends its useful life.
