Strap for Constellation Quadra Quartz 28 Chronograph Stainless Steel / MOP/ Alligator

The lug width of the Constellation 1841.76.61 is 20mm. This dimension, measured between the case lugs, is characteristic of Constellation models from this era and requires straps specifically constructed to this standard. It is not compatible with more modern sizes such as 22mm.

Cognac or cigar brown alligator represents the most refined aesthetic choice, amplifying the formal elegance of the case. Alternatively, vegetable-tanned calf in thin gauges, shell cordovan for those desiring a leather that ages gracefully, or canvas NATO straps for sportive versatility.

To replace the strap, it is necessary to remove the spring bars that secure the strap to the case lugs using a specific tool called a spring bar tool or by consulting a watchmaker. Position the watch on a soft surface, gently press the spring bar from the opposite side until it is completely disengaged, remove the worn strap and insert the new one by aligning the holes to the lugs.

Compatible straps must have a lug width of 20mm. Online you will find a curated selection of 20mm straps ready for shipment, customizable in sizes, initials and thread color. For a complete bespoke experience, the Casati Milano atelier creates custom straps with personal choice of leathers.

A quality leather strap, with vegetable tanning or premium alligator, has an average lifespan of 3-5 years under daily use conditions, depending on exposure to sweat, moisture and UV rays. Premium shell cordovan and alligator can exceed 5-7 years. The lifespan increases significantly if the watch is used occasionally or in formal contexts.
