Omega
Aqua Terra 220.20.38.20.06.001— lug 19mm

The lug width of the Omega Aqua Terra 220.20.38.20.06.001 is 19mm. This measurement must be taken internally between the two lugs, excluding the spring bar pins. A strap with a lug width less than or greater than 19mm would create mechanical instability or undesired play. Always verify with a digital caliper before purchase.

The 220.20.38.20.06.001 with its two-tone Sedna Gold and steel case is enhanced by first-grade French alligator, which creates a pleasant contrast with the noble metals. Japanese shell cordovan develops a patina complementary to Sedna Gold over time. Vegetable-tanned calf leather in dark shades (black leather) reinforces formality. NATO and FKM rubber remain valid options for daily or marine use.

The strap is changed by removing the spring bar pins that connect the lugs to the case lugs. Necessary tools: dedicated spring bar tool or fine needle point. Position the watch securely, press the pin from one side to make it protrude on the other, then extract it. Insert the new strap by aligning the internal holes to the lugs, reinserting the pins and verifying they click correctly.

Yes, any strap with a 19mm lug width is mechanically compatible with the 220.20.38.20.06.001. However, other characteristics (length, thickness, aesthetics) may not be ideal on cases with different proportions. Always verify the specifications of the receiving model before making the change.

A high-quality artisanal leather strap, with proper maintenance (avoid excessive moisture, expose to moderate sunlight to dry dew), lasts an average of 2-3 years in regular daily use. Alligator and cordovan maintain structural integrity longer thanks to superior fiber density. Casati Milano's artisanal warranty is 18 months, covering manufacturing defects and anomalous wear. Any repairs further reduce the attachment base.
