Strap for Planetarium

The lug width of the CKPT7724 is 20mm. Measure precisely between the two vertical lugs where the strap naturally sits. Accurate measurement ensures optimal compatibility with bespoke straps and prevents excessive tension or loose play on the lugs.

For the CKPT7724, African alligator delivers understated elegance that complements rather than competes with the planetary dial. Japanese shell cordovan suits collectors prioritising longevity and natural patina development. Vegetable-tanned calf offers daily comfort with organic ageing characteristics. FKM rubber is the technical choice for more demanding use without compromise to construction integrity.

Remove the horizontal spring bars connecting the strap to the case lugs using a dedicated strap removal tool or small lever. Push gently from the opposite side. Once removed, align the new strap with the lugs and carefully reinsert the spring bars. Perform this operation with precision to avoid scratching the white gold case.

Yes, bespoke 20mm straps are fully compatible with the CKPT7724. The standardised lug width accommodates any quality strap manufactured to this specification, provided the case lugs present no anomalous construction. Premium alligator, shell cordovan, or vegetable-tanned calf straps integrate seamlessly with the case proportions.

Durability depends on material grade and wear patterns. Premium African alligator delivers 5–7 years under regular use before structural fatigue. Japanese shell cordovan with traditional tanning can exceed 10 years with periodic maintenance. Vegetable-tanned calf matches alligator longevity (5–7 years). FKM rubber maintains flexibility for 8–10 years. Consistent daily wear accelerates natural ageing; rotating multiple straps extends each strap's lifespan considerably.
