Frequently asked questions
What is the correct lug width for the Omega Constellation 131.23.39.20.08.001?
The lug width is 24 millimetres, corresponding to the internal distance between the two lateral lugs. To verify, remove the current strap and measure internally: do not confuse with the strap width itself, which is usually 20-22 mm. Precise measurement ensures perfect fit on the case.
What is the best strap to pair with the bi-material Constellation 131.23.39.20.08.001?
For a case in yellow gold and steel, we recommend dark brown alligator, cognac-aged vegetable-tanned calf, or shell cordovan. These materials enhance elegance without style compromises. Avoid saturated colours (red, green): their intensity would prevail over the minimalist geometry of the dial.
How do you change the strap on an Omega Constellation with 24mm lug width?
The strap is inserted into the lateral lugs of the case through small holes. Use a spring bar tool to remove the pin from the current strap, then insert the new strap by aligning the holes with the lugs. Be careful not to scratch the case: work on a soft surface with adequate lighting.
Is there an aftermarket strap compatible with the 131.23.39.20.08.001?
Yes. Any strap with <a href="/pages/terme-glossario/lug-width">24 mm lug width</a> is compatible. Milanostraps offers straps in <a href="/pages/terme-glossario/alligator">alligator</a>, <a href="/pages/terme-glossario/shell-cordovan">shell cordovan</a> and calf with <a href="/pages/terme-glossario/vegetable-tanning">vegetable tanning</a>, customizable in colour, length, initials and stitching thread for perfect adaptation to your wrist.
How long does a leather strap last on an Omega Constellation?
A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts 5-8 years with daily wear. Durability depends on exposure to humidity, perspiration, UV rays and maintenance. Casati Milano straps include an 18-month warranty and can be restored by regenerating the leather after years of wear.
