Frequently asked questions
What is the lug width of the Omega Constellation 123.25.27.60.53.001?
The lug width of the Constellation 123.25.27.60.53.001 is 20mm. This dimension is specific to the 27mm model and is measured as the internal distance between the two attachment points of the case. Any strap for this watch must be exactly 20mm wide to ensure a correct fit and maintain visual harmony with the integrated Griffes.
Which strap is best suited for the Omega Constellation 123.25.27.60.53.001?
High-quality alligator is the most natural choice for this model: the regular grain texture amplifies the geometric elegance of the Griffes and pairs perfectly with the case's golden appliques. Alternatively, vegetable-tanned calf offers a patina that ages beautifully over time. Shell cordovan is ideal for those who desire a strap that progressively evolves, acquiring chromatic and tactile richness.
How do you change the strap on the Constellation 123.25.27.60.53.001?
Changing the strap requires the use of a spring bar remover tool (fork-shaped) or a small flat brush. Position the watch on a soft surface with the strap side facing upward. Insert the spring bar remover into one of the lugs and gently press the elastic pin downward until the lug is released. Replace the old strap with a new one measuring 20mm and reinsert the pin until you hear a security click. If you are unfamiliar with the process, consult a professional watch service.
Which aftermarket strap is compatible with the Omega Constellation 123.25.27.60.53.001?
Any strap with a 20mm lug width is compatible with the Constellation 123.25.27.60.53.001. Our artisanal straps are available in various leathers (alligator, calf, shell cordovan, canvas NATO) and colors, and can be customized in size, initials, and thread type. We recommend visually verifying that the strap is not excessively thick to avoid compromising the harmony with the integrated Griffes.
How long does a natural leather strap last on a watch like the Constellation?
A high-quality artisanal natural leather strap, with vegetable tanning or shell cordovan, has an average lifespan of 5-10 years with daily wear, varying based on frequency of use and climatic conditions. The leather softens over time and acquires a characteristic natural patina. To prolong durability, avoid prolonged exposure to excessive humidity and ensure that the strap dries completely after contact with water. Our Casati Milano atelier provides an 18-month warranty and offers maintenance services to restore worn straps.
