Strap for Hyperchrome Chronograph

The lug width is 20mm. This measurement is determined by the proportions of the 45mm ceramic case and its integrated lugs. To measure correctly, use a calliper positioned between the two upper lugs, in the flat internal section.

For a timepiece of this calibre, we recommend vegetable-tanned alligator or box calf leather in neutral tones (black, grey, taupe). These materials create a striking contrast with the ceramic without competing with the case's geometry. A deployante clasp is always preferable to avoid micro-scratches on the ceramic surface.

Remove the watch from your wrist and place it on a protected surface. Use a spring bar tool to gently compress the internal spring of the lug. Insert the tool's tip under the spring bar, apply light pressure and slide the strap outward. Repeat from the opposite side. To install a new strap, align the keepers with the lugs and snap the spring bars into place with gentle pressure.

Yes, any strap with a 20mm lug width is compatible. Ensure the spring bar is the correct size. We recommend artisanal straps made from superior leather with robust finishes to maintain the aesthetic integrity of a watch in this category. Avoid inexpensive straps that may scratch easily against the ceramic during changes.

A high-quality leather strap (alligator, shell cordovan, calf leather) typically lasts 3-5 years with daily wear and regular maintenance. Durability depends on tanning method, ambient humidity and wearing habits. Vegetable-tanned leather develops a natural patina and may last longer if conditioned regularly with specialised products. Sports rubber straps have similar longevity but require less maintenance.
