Strap for Constellation Quartz 24 Brushed Yellow Gold / Diamond / MOP Stars

The lug width of the Constellation 123.55.24.60.05.001 is 18mm. This dimension is precise and does not tolerate variations: a strap with a different lug width will not mount correctly on the case lugs. To verify, measure the distance between the two internal lugs of the case with a digital caliper, parallel to the dial.

Alligator in cognac or dark brown tones is the most natural choice for this model. The fine grain texture does not visually compete with the brilliance of gold, while creating an elegant contrast. Alternatively, shell cordovan offers superior aesthetic depth, with a patina that evolves over time and harmonizes perfectly with yellow gold.

The strap is secured by two spring bars positioned in the lateral lugs of the case. To remove the old strap, specific tools are required: a spring bar remover (lever tool) or, if unavailable, a flat and thin tool such as a screwdriver tip. Insert the tool under the spring bar from the right side, press upward, and the bar will compress allowing it to slide out of the lug. Repeat for the left side. Proceed in reverse for mounting the new strap.

Yes, provided the lug width is exactly 18mm. A custom artisanal strap with 18mm lugs will mount perfectly. However, it is essential to verify that the strap is created with precision stitching and that the spring bars are of suitable quality (stainless steel, at least 1.5mm diameter) to avoid stress on the yellow gold case.

Durability depends on the quality of leather and usage. An artisanal alligator strap with vegetable tanning lasts an average of 4-6 years of daily wear; shell cordovan, more resistant, can exceed 8-10 years. The stitching, a critical element, maintains structural integrity for at least 18 months with certified artisans. Factors that shorten lifespan: excessive moisture, prolonged sun exposure, dirt not removed. Factors that extend it: rapid drying after water contact, regular cleaning with soft cloth, storage in a dry environment.
