Strap for Chronographs Hockenheim / Stainless Steel / Black

The Laco Chronographs 862089 features an 18mm lug width. This measurement denotes the width of the strap that will fit correctly onto the lugs of the case. To verify compatibility, measure the distance between the inner edges of the two lugs on the case – if you obtain 18mm, the strap will be perfectly compatible. Laco selected this dimension to maintain optimal visual proportions between the 42mm case and the wrist attachment.

For the 862089, we recommend three primary options. Alligator leather in cognac brown or black is the most elegant and durable choice, developing a natural patina that harmonises with the minimalist German design aesthetic. Vegetable-tanned calf in aged brown or deep black offers softness and character development over time. NATO fabric in charcoal grey or black provides practicality and contemporary sportive appeal. Rubber is ideal for intensive use or humid environments. All options must feature an 18mm lug width for correct compatibility.

Strap replacement requires a simple tool: a spring bar tool or small flat-head screwdriver. Place the watch on a soft surface to protect it. Locate the lugs at the case extremities and gently press towards the centre with the tool to release the pin on one side. Extract the old strap and insert the new one, ensuring correct alignment. Repeat the procedure on the opposite side. Verify that both pins are seated deeply within the case lugs to prevent accidental slippage.

Absolutely. The 862089 is fully compatible with any quality strap featuring an 18mm lug width. Artisanal aftermarket straps often represent a superior choice compared to original equipment manufacturer (OEM) straps, offering wider material selection (alligator, shell cordovan, calf leather), refined finishing, and greater customisation possibilities. Always verify the lug width before purchase – it must be precisely 18mm for proper fitment.

Leather strap longevity depends on material type, usage frequency, and maintenance discipline. A quality alligator strap typically endures 5–7 years of regular wear with proper care, including periodic cleaning and protection from excessive moisture. Vegetable-tanned calf, being softer, generally remains functional for 3–5 years before visible deterioration occurs. Lifespan extends considerably if the strap avoids constant humidity exposure, dirt accumulation, and direct UV radiation. A NATO polyamide strap lasts 10+ years without meaningful degradation. Note that patina development and visible wear marks on quality leather represent character acquisition rather than functional failure.
