Strap for Constellation Automatic 35.5 Stainless Steel / MOP

The lug width of the Omega Constellation 1516.76.00 is 18 millimeters. This specification determines strap compatibility: only straps with 18mm lugs can be mounted on this watch without structural modifications. You can verify the measurement by measuring the distance between the two lugs on the case.

For the Constellation 1516.76.00, we recommend alligator (dark brown or blue) for formal elegance, vegetable-tanned calf leather for versatility and patina development over time, or shell cordovan for exceptional quality and natural aging. Your choice depends on your style: if you wear it primarily in formal or business settings, alligator is unmatched; if you seek greater versatility, calf leather offers the best aesthetic and functional balance.

Changing the strap on the Constellation 1516.76.00 is done through the slots on the case lugs. Obtain a spring bar tool (or a two-pronged flat tool), position it in the slots and apply gentle, steady downward pressure: the metal lugs will retract from inside the case. Remove the old strap and insert the new one, ensuring the lugs engage correctly in the opposite slots. If you lack experience, the Casati Milano atelier can perform the change by appointment.

Yes, any strap with an 18mm lug width is compatible with the Constellation 1516.76.00, regardless of brand. However, we recommend choosing equivalent construction quality: fine leathers (alligator, calf, shell cordovan), double stitching, uniform thickness and steel finishes. The handcrafted straps from milanostraps.it guarantee compatibility and longevity, with an 18-month warranty from the Casati Milano atelier.

A quality leather strap, used regularly on a Constellation, has an average lifespan of 3 to 5 years. Factors that influence longevity: frequency of use, direct sun exposure, environmental humidity and maintenance. Vegetable tanning develops natural patina but ages visibly; shell cordovan and alligator maintain structure longer. The 18-month warranty from the Casati Milano atelier covers manufacturing defects; natural leather aging is an expected aesthetic process.
