Strap for Constellation Quartz 27 Brushed Stainless Steel / Red Gold / Diamond / Brown Supernova

The lug width of the Omega Constellation 123.25.27.60.63.001 is exactly 14mm. This measurement identifies the internal distance between the two lugs of the case where the bracelet or strap is attached. Any replacement strap must have a width of 14mm to ensure a correct fit without play or misalignment.

For the Constellation 123.25.27.60.63.001, cognac or black alligator leather represents the most coherent choice with the elegance of the rose gold and steel case. Alternatively, a fine-grain calf leather in tobacco tones or an anthracite grey rubber strap ensure versatile wear while maintaining the proportional aesthetic balance of the watch. NATO straps are not recommended, as they would be too casual for this model.

The strap is changed by removing the spring bars that connect the bracelet to the case lugs. Using a dedicated tool (spring bar tool), position it under the bar and push upward until the internal spring is compressed; the bar will release allowing you to remove the old bracelet. Insert the new strap into the upper lug, then align the lower hole and reinsert the bar by compressing the spring. The operation requires care to avoid scratching the case.

Any strap with a lug width of 14mm is compatible with this model. On milanostraps.it you will find a complete selection of 14mm straps in alligator, calf, shell cordovan and rubber, all customizable in length, initials and stitching thread color. The Casati Milano atelier also offers custom handcrafted strap services with direct selection of leathers.

The lifespan of a leather strap depends on construction quality and conditions of use. A high-quality alligator or calf leather, with regular stitching and correct finishes, typically lasts 3-5 years in daily wear with proper maintenance (protection from moisture, periodic cleaning, leather conditioning). The Casati Milano atelier guarantees 18 months on handcrafted straps, but actual lifespan is generally longer. Factors such as exposure to sweat, water and heat accelerate leather aging.
