Strap for Constellation Quartz 24 Brushed Yellow Gold / MOP

The lug width of the Omega Constellation 123.50.24.60.05.002 is exactly 20mm. This dimension should be measured between the two horizontal pins protruding from the case, using a digital caliper with precision to one-tenth of a millimeter. A compatible strap must strictly respect this measurement to guarantee proper fit and the absence of lateral play.

For the Constellation 123.50.24.60.05.002 in 18k yellow gold, we recommend a cognac alligator, dark brown or tobacco leather: these materials enhance the warmth of the gold without competing visually. Shell cordovan bordeaux represents a sophisticated alternative with natural patina evolving over time. Pearl grey calf leather creates contemporary contrast. We advise against rubber, which contradicts the jewel-like identity of this model.

The strap is changed by means of spring bars (the horizontal pins protruding from the case). Use a spring bar remover tool (or a thin screwdriver and magnifying glass) to gently depress the small internal ball under one of the pins, allowing the pin to slide out of its seat. Repeat on the other side and remove the strap. Reverse the process to install the new one, ensuring both pins are correctly inserted into the case seats.

Yes, any quality strap with a 20mm lug width is compatible with the 123.50.24.60.05.002. Handcrafted 20mm straps from Milano Straps, made in alligator, calf and fine materials, fit perfectly. The important thing is to verify that the strap lugs are made to precise measurements and that the spring bars on your case are in optimal condition.

Durability depends on use and construction quality. A strap in alligator or shell cordovan crafted by an artisan using quality vegetable tanning typically lasts 4-6 years with regular use. Calf leather, being softer, tends to wear out in 2-4 years. The lug, the area of greatest stress, is usually the first to show signs of fatigue. Casati Milano straps include an 18-month warranty and offer repair options beyond the covered period.
