Made to Measure

The strap for this watch is made to measure

On the Omega Constellation the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

What is the lug width of the Omega Constellation 1566.56.00?

The lug width of the Omega Constellation 1566.56.00 is precisely 14 millimetres. This dimension is specific and must be measured accurately to ensure compatibility with aftermarket straps. To measure correctly, position a ruler on the inside of the lug, from the strap bearing point to the opposite edge of the lug shoulder.

Which strap is recommended for the Constellation 1566.56.00?

For the Constellation 1566.56.00 in stainless steel, we recommend alligator, calf or shell cordovan straps in classic colours such as brown, black or burgundy. Alligator enhances elegance with its natural grain, whilst calf offers a softer surface. For sporty use, FKM rubber or military-grade textile straps represent robust and versatile alternatives.

How do you change the strap on an Omega Constellation 1566.56.00?

The strap on the 1566.56.00 is changed by removing the spring bars that secure the strap to the lugs. Use a dedicated spring bar remover tool or a thin flat implement to gently lever and extract the pin. Once removed, the old strap releases easily. To install the new strap, align the holes and reinsert the pin, ensuring it is fully locked on both sides.

How long does a leather strap last on the Constellation 1566.56.00?

The lifespan of a leather strap depends on usage, tanning and maintenance. Quality alligator or calf, with vegetable tanning, typically lasts 3-5 years of daily use. Shell cordovan, thanks to the material's density, easily reaches 5-8 years. Regular rotation between multiple straps significantly extends the life of each one, reducing constant exposure to moisture, perspiration and UV rays.

The next step

The right strap isn’t chosen. It is built, together.
