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.

What is the lug width of the Omega Constellation 131.25.29.20.52.003?
The lug width of the Constellation 131.25.29.20.52.003 is 18 millimetres. This is the distance between the two lateral pins that connect the case to the strap. It is essential to order straps specifically constructed for this width to avoid incompatibility or damage to the pins.
Which strap is best suited for the Omega Constellation 131.25.29.20.52.003?
White or champagne alligator represents the most elegant choice for this model, amplifying the warmth of the Sedna Gold. Alternatively, vegetable-tanned calf leather offers natural patina over time, while NATO fabric in grey tones ensures modern versatility. The choice depends on the intended use and the watch's dial.
How do I change the strap on my Constellation 131.25.29.20.52.003?
Strap replacement requires a specific tool (strap changer or spring bar tool) and precision when handling the lateral pins. Position the watch on a soft surface, use the tool to compress the pin on one side, gently remove the old strap, then insert the new one until it clicks into place. If you prefer to avoid the risk of damage, consult a professional watchmaker.
How long does a leather strap last on a daily-worn watch like the Omega Constellation?
A premium leather strap (alligator or vegetable-tanned calf) worn daily maintains structural and aesthetic integrity between 18 and 36 months, depending on frequency of use, climate, and care applied. Exposure to moisture, sweat, and sunlight shortens this duration. The Casati Milano warranty covers 18 months of normal use, with the possibility of restoration or lining replacement beyond that period.
