Frequently asked questions

What is the lug width of the Omega Constellation 131.50.29.20.52.002?

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of this Constellation is 18mm. This dimension is standard for women's models in the collection and allows you to match a wide selection of artisanal straps without the need for adapters.

Which leather strap is most suitable for the Omega Constellation 131.50.29.20.52.002?

For this yellow gold model, we recommend Nile <a href="/pages/termine-glossario/alligatore">alligator</a> in cognac or dark brown tones, or premium calf with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>. Alligator provides formal elegance and its natural texture pairs perfectly with the lustre of yellow gold. Vegetable-tanned calf offers a patina that ages beautifully and nobly over time.

How do you replace the strap on a watch with an 18mm lug width?

Insert the spring bar tool perpendicularly to the lug from the opposite side of the buckle. Gently compress the internal spring and extract the pin. Repeat for the second side. The new strap is installed by reversing the operation. If you have a <a href="/pages/termine-glossario/deployante">deployant clasp</a>, you will also need to remove the bracelet fixing pin. Never force it: gentle pressure is sufficient to avoid damaging the gold lugs.

Which aftermarket straps are compatible with the Constellation 131.50.29.20.52.002?

Any strap with an <a href="/pages/termine-glossario/misura-ansa">18mm lug width</a> is compatible with this model. On milanostraps.it you will find a curated selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">18mm straps</a> in leather, technical rubber, NATO fabric and shell cordovan, with the option to customize size, initials and stitching thread.

How long does a natural leather strap last on a wristwatch worn daily?

An artisanal quality leather strap, with vegetable tanning or Hermès treatment, has an average lifespan of 3-5 years with daily wear. Factors such as humidity, sun exposure and frequency of wear affect longevity. Nile <a href="/pages/termine-glossario/alligatore">alligator</a> tends to last slightly longer than standard calf. Casati Milano offers an 18-month warranty on straps made in the atelier and provides advice on maintenance and replacement.
