Strap for Constellation Quartz 24 Brushed Stainless Steel / Gold Claws / Champagne MOP

The lug width of the Constellation 123.20.24.60.57.002 is exactly 20 mm. This is the distance between the strap attachment pins at the case lugs. It is essential to verify this dimension before purchasing an aftermarket strap, as a different lug width (18 mm or 22 mm) will not fit correctly and may damage the case.

For the Constellation 123.20.24.60.57.002, alligator straps with vegetable tanning represent the historical and most elegant choice. A dark brown alligator, aged cognac, or moro leather emphasizes the yellow gold warmth of the case. For contemporary versatility, a black or graphite grey calf leather maintains formal sobriety. Cotton-nylon NATO straps offer dynamism for casual wear, while vulcanized rubber is ideal for daily use.

To change the strap, you need to remove the spring bars that secure the strap to the case lugs. Using a dedicated spring bar tool (available at jewelers or online), gently depress the pin by pushing it toward the case interior, allowing one end of the old strap to slide out. Repeat on the other side. Insert the new strap by aligning the holes with the lugs and ensure the spring bars click securely into position. If you are not experienced, it is advisable to consult a professional watchmaker.

Any strap with a 20 mm lug width is compatible with the Constellation 123.20.24.60.57.002. Milanostraps.it offers a complete catalog of 20mm straps in various materials (alligator, calf, bovine leather, NATO, rubber). Straps can be personalized in size, initials, and stitching thread type. The Casati Milano atelier also offers bespoke tailoring services to guarantee impeccable fit and aesthetics.

The durability of a leather strap depends on the material and usage. A vegetable-tanned alligator strap, if properly cared for (protection from moisture, heat, and stains), can last 3-5 years of daily use. A superior quality calf has similar durability. NATO and rubber straps tend to last longer (5-10 years) due to their inherent resistance. Natural leather wear, with the development of patina and texture, is normal and desirable: it testifies to the authentic use of the watch. Quality straps crafted by artisans guarantee superior longevity compared to industrial production.
