Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Stainless Steel / Sedna Gold / Diamond / Pink - Ruby / Bracelet

The Omega Aqua Terra 220.25.34.20.60.001 is fitted with a lug width of exactly 16mm. This measurement is essential for selecting a compatible strap: 14mm, 18mm or 20mm straps cannot be fitted to the case without modifications. You can verify the measurement by positioning a digital caliper between the two vertical lugs of the case, taking care to exclude the lateral protrusions.

The best strap depends on its primary use. For formal and prestigious settings, we recommend alligator in cognac or medium brown tones, which complements the warmth of Sedna Gold perfectly. If you prefer versatility, vegetable-tanned calf leather offers softness and natural patina. For sports or coastal use, FKM rubber or polyurethane with a deployant buckle maintain the nautical character. Shell cordovan represents an exceptionally elegant intermediate choice, with a natural sheen that increases over time.

The strap is attached to the case lugs via spring bars: you must use a dedicated tool (spring bar tool) to slightly lift the internal spring of the bar, release the end of the old strap and insert the new one. The operation requires care to avoid damaging the case finishing. If you prefer to avoid any risk, the Casati Milano atelier offers personalised strap-changing service.

Yes, any 16mm strap is dimensionally compatible with the Omega Aqua Terra 220.25.34.20.60.001, provided the spring bars are of the correct length. We recommend verifying that the nominal width is actually 16mm and that the construction quality is consistent with the watch's value. Milano Straps offers artisanal leather straps of excellence with customisation and 18-month warranty.

A quality leather strap, with vegetable tanning, typically lasts 4-7 years with daily use, reducing to 2-3 years if frequently exposed to water, sweat or humidity. The Aqua Terra is a 150-meter water-resistant watch with a water-resistant case: we recommend using rubber or polyurethane straps for extended water activities, and periodically alternating with leather straps to preserve longevity. The patina that a leather strap develops over time is nonetheless an appreciated aesthetic characteristic.
