Strap for Big Crown Complication Stainless Steel / Silver

The lug width of this model is precisely 20 mm. This measurement should be verified using a digital calliper positioned between the two lug holes on the case, ensuring proper tolerances when installing an aftermarket strap.

Alligator leather in medium brown (tabac) or black represents the most coherent choice, as its natural grain texture dialogues beautifully with the aviation aesthetic. Quality alternatives include vegetable-tanned calf leather in warm tones (bourbon) or a densely woven cotton NATO strap.

Strap replacement requires a spring bar tool. Insert the tool into the slot beneath the lug, press inward gently and extract the pin holding the strap. Install the new 20 mm strap by reversing the procedure, ensuring the spring bar clicks securely into both lug holes.

Yes, this model accepts any quality strap with a 20 mm lug width. Ensure the strap thickness does not exceed the original and that the lug attachments remain perfectly vertical for secure case fixation.

A quality artisanal alligator or calf leather strap typically lasts 2–3 years with daily wear, extendable to 5–7 years with regular maintenance including cleaning, drying and protective treatments. The patina developed over time increases the aesthetic value of the watch.
