Frequently asked questions
What is the lug width of the Omega Constellation 123.10.24.60.51.002?
The Omega Constellation 123.10.24.60.51.002 is equipped with 18 millimeter lugs. This measurement corresponds to the distance between the pins that connect the strap to the case. Any handcrafted strap made for 18mm lugs will be perfectly compatible without the need for modifications.
What is the best strap for the Omega Constellation 123.10.24.60.51.002?
The best strap depends on usage and personal preferences. For formal elegance, we recommend polished black alligator or vegetable-tanned calf leather. For versatility, a tobacco brown calf with natural patina offers refinement and practicality. Shell cordovan is ideal for those seeking natural luster and structural rigidity. A handcrafted personalized strap from Casati Milano allows you to choose leather, color, and finishes according to your taste.
How do you change the strap on an Omega Constellation 123.10.24.60.51.002?
Strap replacement requires a spring bar tool, a small metal lever available commercially. Position the lever under the lug, apply gentle pressure to compress the internal elastic pin, and pull the old strap outward. Repeat on the other side. Insert the new strap by aligning the holes to the case, use the tool to compress the pin, and slide the strap into position until it clicks into place. If you prefer to avoid any risk, the Casati Milano atelier offers a strap change service with warranty.
Which aftermarket strap is compatible with this Omega Constellation?
Any strap with 18 millimeter lugs is compatible. Milano Straps offers a complete collection of handcrafted 18mm straps in alligator, calf, shell cordovan, and rubber. The straps are customizable in size, color, initials, and stitching type. Always verify that the thickness does not exceed 4-5 millimeters to maintain the elegance and visual proportion of the compact case.
How long does a leather strap last on an Omega Constellation 123.10.24.60.51.002?
Durability depends on the material, usage, and maintenance. An alligator or shell cordovan strap, with proper care, can last 5-8 years in daily use. Calf leather with vegetable tanning, being more absorbent, has slightly shorter lifespan if frequently exposed to moisture. FKM rubber has greater durability, 8-10 years. Milano Straps guarantees 18 months on all handcrafted straps and offers regeneration and restoration services to extend their life.
