Accepted Answer

For a Constellation in 18k Red Gold, we recommend straps in alligator with polished or satin finishes, or high-quality calf leather with vegetable tanning. Alligator reflects the sophistication of the precious metal, while calf leather offers versatile pairing and natural patina over time.

The strap is changed via the lug and case attachment. Using a gentle spring bar tool, you must push the spring bar under the lug and remove the old strap, then insert the new one through the same lug.
