Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Stainless Steel - Sedna Gold - Diamond / Canopus Supernova / Alligator

The lug width of model 131.28.29.20.52.001 is 18mm. This measurement refers to the distance between the inner walls of the two lugs where the strap attaches to the case. It is essential to verify this measurement with a digital caliper before ordering a strap, as even a variation of ±0.5mm can affect the comfort and stability of the strap on the case.

For a 29mm Constellation in Sedna Gold and steel, alligator represents the most resonant choice from both an aesthetic and tactile perspective. An alligator in cognac or chocolate tones amplifies the warmth of the gold and creates an elegant contrast. Vegetable-tanned calf leather is an excellent alternative for those desiring chromatic evolution over time thanks to natural patina development. Shell cordovan offers an intrinsic brilliance that dialogues magnificently with the steel dial.

The strap on the Omega Constellation 131.28.29.20.52.001 is changed using a specific tool (spring bar tool or extractor) to remove the spring bars that connect the strap to the lugs. Position the tool in the small slot of the spring bar, apply gentle pressure to compress the bar, and remove the old strap. The operation requires delicacy to avoid scratching the case. If you are unsure, it is advisable to contact an authorized Omega service center or an experienced craftsman.

No, the 18mm lug width is specific to the 29mm Constellation model. 18mm straps are not compatible with Omega models that use different measurements (such as 20mm, 22mm, or 16mm). However, any quality strap manufactured for 18mm – whether from specialized or artisanal brands – is installable on this reference, provided it respects standard dimensional tolerance.

The lifespan of a leather strap depends on maintenance, climate, and intensity of use. A quality artisanal alligator or calf strap, worn daily with reasonable care, maintains optimal condition for 3-5 years. Exposure to high humidity, constant perspiration, and direct sunlight accelerates aging and can reduce lifespan to 2-3 years. A technical rubber or NATO strap presents a longer lifespan (5-7 years) due to material resistance. Seasonal rotation among multiple straps significantly extends the life of each one.
