Frequently asked questions
What is the exact lug width of the Omega Constellation 1391.71.00?
The lug width of the Constellation 1391.71.00 is 18mm. This width is determined by the internal distance between the attachment pins and is specific to this model. Using straps of different width would result in improper fitting and could damage the case.
What strap material is most recommended for the Constellation 1391.71.00?
Alligator represents the ideal pairing thanks to its fine grain that perfectly proportions to the compact case dimensions (27.50mm). Vegetable-tanned calf offers a more contemporary alternative, while shell cordovan provides structure and brilliance. The choice depends on the context of use: elegant for alligator, versatile for calf, sporty-formal for cordovan.
How do you change the strap on an Omega Constellation?
Changing the strap requires a specific tool called a spring bar tool. Position the watch with the case side facing you, locate the small hole beside each pin and insert the tool to slide the pin out of the lugs. Reverse the procedure for the new strap. If you are not experienced, consult a professional to avoid scratching the case.
Are aftermarket straps compatible with the Constellation 1391.71.00?
Yes, provided they are certified for 18mm lug width. Milanostraps offers a complete collection of handcrafted compatible straps, customizable in leather, color and details. Before purchasing, always verify that the seller specifies compatibility with this measurement, as straps that are even slightly oversized compromise the fitting.
How long does a leather strap last on an Omega Constellation?
Durability depends on daily use and leather quality. A premium alligator or calf, with minimal maintenance (avoid standing water, abrasive cleaners), typically lasts 4-6 years with regular wear. Vegetable-tanned leather tends to last slightly less than chrome-tanned leather. Milanostraps guarantees its straps for 18 months from purchase, with the option of replacement if deterioration is anomalous.
