Fluco's Chicago is a simple strap with unusually good leather. Horween shell cordovan has a smooth surface, dense feel, and depth of color that make the strap look richer than standard calfskin, even though the build stays flat and restrained.

That makes the Chicago especially well suited to dress watches, slim cases, and vintage-leaning designs. It adds richness without adding bulk.

Material & feel

This strap is made from vegetable-tanned Horween shell cordovan, a dense equine leather known for its smooth surface, durability, and slow-developing character over time. Compared with softer calfskin, shell cordovan feels firmer and more compact, with a surface that stays relatively smooth as it bends and wears.

Fluco keeps the construction straightforward to let the leather stand on its own. The profile is flat, the edges are painted, sanded, and polished by hand, and the underside is lined in hypoallergenic leather. Authentic Horween lining may show natural tanning marks or part of the tannery stamp.

Sizing & fit help

This slim strap keeps the watch close to the wrist without extra bulk at the lugs. The leather is flexible from the start and breaks in quickly.

Length & wrist size:

  • Regular: 118mm / 75mm (fits wrists approx. 6.75–7.5in)
  • Short: 105mm / 65mm (fits wrists approx. 6.25–7.0in)

If your wrist sits near the overlap between sizes, either length can work. A shorter strap reduces tail and positions the buckle more tightly, while a longer strap provides more room and tail.

Measurements exclude the buckle.

Care & wear

Splash resistant, suitable for light moisture such as hand washing or rain.

Wipe gently with a soft, dry or slightly damp cloth as needed. Do not use leather creams, conditioners, or cleaning products. Avoid prolonged exposure to water or perspiration. Allow the strap to air dry naturally if it becomes damp. Light surface marks may be gently brushed with a soft cloth once dry.
