Frequently asked questions
What is the exact lug width of the Omega Aqua Terra 2517.30.00?
The lug width of the Omega Aqua Terra 2517.30.00 is 20 millimetres. This measurement is the standard for wristwatches with a 39.2mm case diameter and ensures balanced visual proportions between the case and strap.
What is the best strap material for the 2517.30.00?
It depends on the intended use. For predominantly formal wear, vegetable-tanned alligator leather enhances the dress character of the watch. Shell cordovan is ideal if you desire a natural patina over time. For frequent water use, an FKM rubber strap is the most reliable solution given the model's 150-metre water resistance.
How do you correctly measure the lug width of a watch?
Measure the internal distance between the two lugs that protrude from the watch case. On an Omega Aqua Terra 2517.30.00, this distance is 20mm. Use a digital calliper for maximum accuracy. If you are unsure, consult an experienced watchmaker.
Are aftermarket 20mm straps compatible with the Omega Aqua Terra 2517.30.00?
Yes, all straps with a 20mm lug width are compatible with the 2517.30.00. Ensure the strap is designed for standard lugs (not integrated bracelets). Our handcrafted straps are 100% compatible and shipped ready to use.
How long does a leather strap last on a wristwatch?
A quality leather strap with vegetable tanning and hand-stitching typically lasts 3-5 years with moderate daily use. Durability depends on exposure to moisture, perspiration and sunlight. Shell cordovan lasts longer (5-8 years). Atelier Casati Milano guarantees 18 months on all handcrafted straps.
