FAQ
What is the lug width of the Laco Chronographs 861815?
The Laco Chronographs 861815 features an 18mm lug width. This measurement represents the distance between the two lugs on the watch case where the strap attaches. It is essential to verify that any replacement strap has this exact measurement to ensure proper installation and security.
Which strap is recommended for the Laco 861815?
The Laco Chronographs 861815 pairs excellently with various materials. An alligator strap with vegetable tanning emphasises refined character, whilst a fine-grained English calf maintains sportive versatility. For a purely technical approach, a cotton NATO strap or a black technical rubber strap are functional choices that enhance the watch's aviator heritage.
How do I change the strap on a watch with 18mm lugs?
To change the strap, you'll need a dedicated spring bar tool to remove the spring bars connecting the strap to the case lugs. Position the tool in the notch of the bar, apply gentle pressure inward and downward to release the old strap. Insert the new strap, ensuring the ends fit perfectly into the case attachments.
Is an aftermarket strap compatible with the Laco 861815?
Yes, any strap with an 18mm lug width is compatible with the Laco Chronographs 861815. Artisanal straps from specialised manufacturers often offer superior quality to standard OEM straps. Always verify that the strap is explicitly labelled as 18mm before purchase.
How long does a leather strap last on the Laco 861815?
The lifespan of a leather strap varies depending on the material and wear conditions. Quality calf or alligator with vegetable tanning typically lasts between 3 and 5 years with moderate daily use. Factors such as humidity, sun exposure, and perspiration accelerate ageing. With proper maintenance (regular cleaning and storage in dry environments), longevity extends significantly.
