Frequently asked questions
What is the lug width of the Omega Constellation 123.25.24.60.57.001?
The Omega Constellation 123.25.24.60.57.001 is fitted with a 20 millimeter lug width. This measurement represents the distance between the two lugs on which the strap is inserted. It is essential to verify that the replacement strap is compatible with this exact specification to ensure a correct and secure fit.
What is the best strap for the Omega Constellation 123.25.24.60.57.001?
Alligator remains the most prestigious choice thanks to its fine grain and natural chevron effect, which reflect the inherent elegance of this timepiece. However, calf and shell cordovan represent excellent alternatives if you desire a different texture or an aging patina. The choice depends on the context of use and personal aesthetic preferences.
How do you change the strap on an Omega Constellation with 20mm lug width?
To change the strap, you need to use a spring bar tool to remove the lugs. Insert the tool horizontally under the lug, compressing the internal spring that allows the lug to retract. Once retracted, the lug slides out from its seat. Repeat the operation on the other side. To insert the new strap, align the holes and reinsert the lugs until you hear the locking click. If you are inexperienced, we recommend contacting a specialized watchmaker.
Are aftermarket straps compatible with the Omega Constellation 123.25.24.60.57.001?
Yes, provided they are constructed for the specific 20 millimeter lug width. All straps offered by Milano Straps and the Casati Milano atelier have been tested on this reference and guarantee technical compatibility. It is crucial to avoid straps with incorrect measurements (18mm or 22mm), which would cause dangerous play and could compromise the security of the watch.
How long does a leather strap last on an Omega Constellation?
The durability of a leather strap depends on the quality of the tanning, usage, and climatic conditions. A high-quality alligator or shell cordovan strap, vegetable tanned, can last 5-7 years of regular use. Natural leather ages gradually, developing patina and character. Factors such as excessive humidity, prolonged sun exposure, and frequent sweating accelerate its aging. The Casati Milano atelier offers an 18-month warranty on all bespoke straps.
