The Chronographs 861916, seen from the bench

The Laco Chronographs 861916 is a contemporary chronograph with a 44mm stainless steel case housing an ETA caliber 7750 movement. It inherits the philosophy of original Fliegeruhren aviation instruments while using modern construction. The watch features a readable dial, well-positioned chronograph subdials, and sharp hand geometries designed for instant time reading in critical conditions. The 20mm lug width balances the case proportions perfectly and allows for diverse strap options, from textile to premium leather solutions.

Frequently asked questions

What is the lug width of the Laco Chronographs 861916?

The Laco Chronographs 861916 features lugs of 20mm width. This measurement refers to the distance between the inner shoulders of the lugs and is the international standard for sports watch straps. The 20mm width was selected to balance the visual proportions of the 44mm case whilst ensuring maximum compatibility with quality aftermarket straps.

Which strap do you recommend for the Laco Chronographs 861916?

For the Laco Chronographs 861916, we recommend an alligator strap with vegetable tanning for formal applications, or vegetable-tanned calf in brown or black tones for daily versatility. For sports use or humid environments, a nylon ripstop NATO or structured rubber pad ensures practicality and durability. Your choice depends on context: leather humanises the watch, rubber renders it a tool.

How do I change the strap on my Laco Chronographs 861916?

The strap is replaced by removing the spring bars that connect the lug to the case. Using a spring bar remover tool, apply gentle downward pressure on one of the bars, then extract the old strap. Insert the new strap by aligning the holes with the case lugs and snap the spring bars into position. Ensure the strap is firmly seated before wearing the watch.

Are there aftermarket straps compatible with the Laco Chronographs 861916?

Yes, the Laco Chronographs 861916 is compatible with any 20mm strap. Milano Straps offers a complete collection of artisanal straps in this size: alligator, shell cordovan, calf, NATO and rubber. Each strap is crafted with attention to constructive detail and proportions, ensuring both mechanical compatibility and aesthetic coherence with the steel case.

What is the typical lifespan of a leather strap for the Laco Chronographs 861916?

A quality leather strap with vegetable tanning and artisanal construction lasts 3-5 years in daily use, provided it receives periodic maintenance (gentle cleaning, seasonal waterproofing). Longevity depends on exposure to moisture, perspiration and UV rays. The patina that develops over time is not deterioration, but natural ageing. Structured rubber, by contrast, maintains its properties for 5-7 years before elasticity diminishes.
