Strap for Constellation Quartz 24 Brushed Stainless Steel / Diamond / MOP

The lug width of the Constellation 123.15.24.60.55.006 is exactly 20mm. This dimension is essential to preserve the architectural proportions of the 24mm case. Any compatible strap must have a width of 20mm in the section that sits between the watch lugs.

Alligator remains the most harmonious choice with this model's original design: the natural grain of crocodile leather dialogues elegantly with the metallic lugs. Alternatively, vegetable-tanned calf leather offers authentic craftsmanship and develops a natural patina over time. Shell cordovan in matte shades (burgundy, cognac) represents a contemporary high-quality solution.

Use a digital caliper or millimeter ruler. The measurement must be taken at the inner base of the lug, at the point where the strap actually rests on the case. Measure perpendicularly between the two internal contact points of the lugs: the result should be 20mm. An external or superficial measurement may provide inaccurate data.

Yes, any strap built to 20mm lug width is fully compatible. However, it is advisable to choose materials and colors that respect the model's proportionality: noble leathers (alligator, cordovan, vegetable-tanned calf), restrained thickness (2-2.5mm), and finishes that dialogue with the stainless steel case will maintain aesthetic coherence.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) subjected to daily use maintains structural integrity for 3-5 years. Variables such as sun exposure, humidity, and frequency of use affect longevity. The standard warranty on artisanal straps is 18 months; beyond that period, maintenance aims to preserve the patina rather than functional resistance.
