Frequently asked questions
What is the lug width of the Omega Aqua Terra 220.58.34.20.99.004?
The lug width is exactly 16mm. This measurement corresponds to the space available between the lugs of the case where the strap is inserted. A 16mm strap will have a visible width of approximately 15mm on the dial to ensure aesthetic balance between the case and the bracelet.
Which strap material is most suitable for the Sedna Gold Aqua Terra?
African alligator is the most coherent choice for Sedna Gold: its natural geometric grain creates an optical vibration that amplifies the luminosity of rose gold. Alternatively, vegetable-tanned calf offers a more understated profile, while a burgundy shell cordovan introduces narrative depth with a patina that evolves over time toward dark violet hues.
How do you change the strap on a watch with 16mm lugs?
To change the strap, use a spring bar tool or a small screwdriver. Gently press downward on the lug's spring pin from the side of the strap being removed, sliding the bar laterally. Once extracted, insert the new strap into the case slot, ensuring the spring positions correctly in the anchor holes. Proceed on the other side and verify that the strap is perfectly aligned.
Can I use aftermarket straps compatible with this Omega model?
Yes, any strap with a 16mm lug width is compatible with the Omega Aqua Terra 220.58.34.20.99.004. Verify that the total width of the strap, measured including the material that fits the lug, does not exceed 16mm. It is advisable to choose superior quality straps (alligator, shell cordovan, vegetable-tanned calf) that enhance the preciousness of the Sedna Gold.
How long does a leather strap on a luxury watch typically last?
The lifespan of a leather strap depends on the material and usage. High-quality alligator typically lasts 3-5 years with regular wear, while shell cordovan can exceed 5-7 years thanks to its fibrous density. Vegetable tanning tends to last 2-4 years. Factors such as sun exposure, humidity, and frequency of use significantly influence longevity. Milano Straps guarantees 18 months on custom-made straps crafted by the Casati Milano atelier.
