Frequently asked questions
What is the exact lug width of the Omega Constellation 131.55.28.60.99.006?
The lug width of the Constellation 131.55.28.60.99.006 is 20mm. This measurement should be verified by placing a ruler perpendicular to the case, from inner wall to inner wall. The watch strap lugs must accommodate the spring bar with a maximum tolerance of ±0.2mm to ensure secure fastening without play.
What is the best watch strap for the Omega Constellation 131.55.28.60.99.006 in yellow gold?
For the yellow gold Constellation, alligator remains the canonical choice: the regular grain of the leather creates an elegant aesthetic contrast. Alternatively, vegetable-tanned calf offers a more contemporary sobriety. Shell cordovan is ideal for collectors who desire a patina that evolves over time, parallel to the natural aging of gold.
How do you change the watch strap on the Constellation 131.55.28.60.99.006?
The Constellation uses removable spring bars that connect the lugs to the strap lugs. With a specialized tool, gentle pressure is applied to one of the spring bars to release the strap from the case. The new strap is then inserted, aligning the case shoulders into the strap lugs, then the spring bar is inserted into the second hole until it snaps into position.
Which aftermarket straps are compatible with the 20mm lug width of the Constellation?
Any 20mm strap is technically compatible with the Constellation 131.55.28.60.99.006, provided the strap lugs are correctly calibrated. We recommend certified quality artisanal straps: milanostraps.it offers a complete collection of 20mm in premium leathers (alligator, calf, shell cordovan), with possibilities for customization in length and color.
How long does a leather strap typically last on the Constellation 131.55.28.60.99.006?
A premium leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with moderate daily use. Longevity depends on tanning, sun exposure, humidity, and frequency of use. Vegetable-tanned leather ages more nobly and often exceeds 5 years. Casati Milano provides straps with an 18-month warranty and offers repair services to extend their useful life.
