Strap for Constellation Quartz 27 Polished Red Gold / Silver

The lug width of reference 123.50.27.60.02.003 is 18 millimetres. This Omega standard is specific to the women's Constellation models of this generation and is fundamental for the compatibility of any aftermarket strap. An 18mm strap must slide into the case lugs without play or forcing.

To enhance the 18-carat rose gold of the 123.50.27.60.02.003, the ideal choices are: natural alligator in vegetable tanning (understated luxury), Hermès brown or cognac calf (timeless classic), shell cordovan with rich aging (evolved sophistication), black FKM rubber (modern functionality). Avoid cool tones such as pure anthracite grey unless paired with a rose gold buckle.

Strap replacement is straightforward if the integrated bracelet is not permanently soldered to the case. Use a dedicated tool (spring bar tool) to remove the pins from the 18mm lugs. Position the new 18mm strap and reinsert the pins into the attachments, ensuring the strap is centred and the leather's curve embraces the case without tension. If the bracelet is integrated, contact an authorized Omega service centre.

Yes, any strap with an 18mm lug width is dimensionally compatible. However, verify that the leather thickness is proportionate to the case's delicacy (maximum 3–3.5mm) and that the keepers do not generate stress. Custom-made straps from Milano Straps guarantee this construction precision, offering customization in choice of leather and finish.

A quality leather strap (alligator, calf, shell cordovan) on a watch worn 4–5 days per week lasts on average 3–5 years before requiring replacement. Durability depends on usage (sports, office, formal wear), tanning method (vegetable tanning resists better), climate (humidity accelerates aging) and maintenance. Casati Milano straps include an 18-month warranty against manufacturing defects.
