Frequently asked questions
What is the lug width of the Omega Constellation 123.20.27.60.57.004?
The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Constellation 123.20.27.60.57.004 is exactly 20mm. This intermediate dimension is specific to the feminine models in the Constellation line and allows for a wide range of customizations through compatible aftermarket straps.
Which strap is best suited for the Omega Constellation 123.20.27.60.57.004?
For this model with mother-of-pearl dial and two-tone case, dark blue <a href="/pages/termine-glossario/alligatore">alligator</a> in <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> represents the most refined pairing, creating tonal harmony. Alternatively, smooth box calf emphasizes the case details, while burgundy <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> adds color depth and develops patina over time.
How do you change the strap on an Omega Constellation?
To replace the strap on the Constellation 123.20.27.60.57.004, use a spring bar tool to compress the elastic pins at the extremities. Position the tool tip in the dedicated holes under the lugs, gently push to extract the pins, remove the worn strap and insert the new one by leveraging the springs. With Atelier Casati Milano, this service can be performed at our location to ensure precision without scratches.
Is an aftermarket strap compatible with the Omega Constellation 123.20.27.60.57.004?
Yes, any strap with a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 20mm is compatible. On milanostraps.it you will find a selection of artisanal <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> ready for shipment, made in alligator, cordovan, calf and other premium materials.
How long does a leather strap last on an Omega Constellation?
Durability depends on the material and daily wear. An <a href="/pages/termine-glossario/alligatore">alligator</a> or <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> strap can last 5-8 years with proper maintenance; the more common calf has a lifespan of 3-5 years. Artisanal Casati Milano straps come with an 18-month guarantee, but with proper care (avoid prolonged water exposure, remove perspiration, apply natural conditioners) the actual lifespan extends significantly beyond this period.
