Frequently asked questions
What is the best strap for the Constellation 123.55.35.20.52.002 in yellow gold?
For the yellow gold Constellation, we recommend tobacco brown alligator or vegetable-tanned calf leather. Alligator emphasizes formal elegance through its natural grain; vegetable-tanned calf offers everyday comfort and a patina that improves over the years. The choice depends on your intended use and personal aesthetic preferences.
Can I use an aftermarket strap on this Constellation?
Yes, any strap with a 16mm lug width is compatible with the Constellation 123.55.35.20.52.002. Online you will find 16mm straps in various materials and colors. For optimal results in terms of quality and durability, we advise against cheap straps: choose vegetable-tanned leathers or certified elastomers.
How long does a natural leather strap last on the Constellation 123.55.35.20.52.002?
A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3-5 years of daily wear, depending on climate conditions, sun exposure and frequency of use. Leather tends to dry out over time and lug wear increases progressively. To extend the lifespan, we recommend alternating straps and avoiding prolonged exposure to salt water.
