Strap for Malvern C5 MK1 Stainless Steel / Black / Bracelet

The Christopher Ward C5SKS features a lug width of 18mm. This is a particular specification requiring straps of exactly 18mm width to fit correctly onto the integrated lugs of the case. Measurement should be taken from the inner shoulder to inner shoulder of the lug, perpendicular to the strap's length.

For the C5SKS, alligator straps in black with stainless steel deployante buckles represent maximum formal choice, preserving the minimalist elegance. Alternatively, vegetable-tanned calf leather in cognac brown introduces aesthetic warmth whilst maintaining dress watch dignity. For more versatile daily wear, cotton or textured rubber NATO straps are durable and practical solutions, especially in warm climates or informal contexts.

The C5SKS lugs are integrated into the case. Strap replacement is achieved using a lever tool (spring bar remover) to extract the spring bars fixing the strap to the lugs. Insert the flat edge of the lever into the grooves on the lug's sides, press gently downward to compress the internal spring, then remove the old strap. Repeat the operation in reverse with the new 18mm strap.

Yes, all quality straps manufactured with 18mm lug width are compatible with the C5SKS. The key is verifying that the external width is precisely 18mm and that the strap's shoulders do not present excessive thickness, which could obstruct insertion into the spring bars. Artisanal leather straps, textured rubber, and technical fabrics maintain correct geometry and guarantee durability over time.

A fine leather strap of good craftsmanship, worn daily and subjected to periodic maintenance (gentle cleaning and conditioning with natural creams), has an average lifespan of 3-5 years. Materials such as alligator or shell cordovan, owing to fibre density, reach 5-7 years. Lifespan depends on ambient humidity, frequency of use, and maintenance practice. Vegetable-tanned leathers age by developing characteristic patina rather than degrading.
