Frequently asked questions
What is the lug width of the Omega Constellation 131.55.28.60.55.003?
The lug width of this model is 18mm. This specification is essential when selecting a compatible strap: position a digital caliper between the lugs protruding from the case, measuring from inner edge to inner edge. The lug width remains constant; it is the strap length that varies according to wrist size.
What strap material is recommended for the Constellation 131.55.28.60.55.003 in Sedna Gold?
To enhance the warmth of Sedna Gold, we recommend natural alligator in cognac or brown tones, or vegetable-tanned calf leather for a more sustainable option. A glossy black FKM rubber offers modern versatility, while a pearl grey canvas NATO strap is ideal for casual settings. Avoid cool tones that might compete with the rose gold.
How do you change the strap on the Constellation 131.55.28.60.55.003?
The strap is secured by two spring bars connecting the case lugs. To replace it: use a spring bar tool to push the small elastic pin from one side, free the old strap, and insert the new one by aligning its lug with the holes. Do not force: the pins must snap into position with firm but smooth pressure.
Can I use an 18mm aftermarket strap on this Omega Constellation?
Yes, any strap with an 18mm lug width is compatible. Verify that the leather thickness is proportioned to the case diameter (28mm suggests thicknesses between 4mm and 5mm to maintain proper proportions). A quality artisanal strap, crafted from vegetable-tanned leather or alligator, further enhances the character of the Constellation.
How long does a leather strap last on the Constellation 131.55.28.60.55.003?
Durability depends on usage, tanning method, and care. A well-maintained alligator or vegetable-tanned calf strap lasts 3-5 years with moderate daily wear; FKM rubber reaches 4-6 years without significant degradation. Critical factors: avoid prolonged moisture exposure, regularly air the strap, and apply a conditioning balm every 6-8 months for fine leathers.
