Strap for Circularis Blue

The lug width of the CC108 is 20mm. This specific measure determines compatibility with aftermarket straps. To verify it, measure the horizontal distance between the inner edges of the lugs on the case. Correct measurement is essential before purchasing any replacement strap.

The choice depends on intended use and aesthetic preference. A dark brown or black alligator amplifies the watch's formal and minimalist character. For daily wear, calf leather with vegetable tanning offers practicality and natural patina development. NATO straps in grey taupe or navy blue create compelling contrast without excess. For sport, Tropic rubber maintains aesthetic sobriety.

Use a spring bar tool to remove the springs securing the old strap. Insert the tool into the lateral slots at the lugs, apply gentle downward pressure to retract the spring, and slide out the strap. For installation, align the new strap's holes with the lugs and reinsert the springs until you hear the locking click.

Durability depends on frequency of use, climate, and tanning type. Alligator leather with vegetable tanning typically lasts 3–5 years under regular use. Leather develops natural patina, darkening and hardening progressively. Thin calf may require replacement every 2–3 years. Tropic rubber, being more resistant, exceeds 5 years. Regular maintenance—avoiding prolonged moisture, applying specific balms—extends strap lifespan.
