Strap for Seamaster Aqua Terra 150M Co-Axial 30 Stainless Steel / Yellow Gold / Diamond / MOP

The Omega Aqua Terra 231.28.30.20.55.002 has a lug width of exactly 20mm. This parameter is essential to verify the compatibility of any aftermarket strap: the case lugs are spaced 20mm apart from each other, both internally and in the lug profile itself. When purchasing a strap, always ensure it is specified for 20mm to avoid incompatibility.

For the 231.28.30.20.55.002, we recommend a quality artisanal alligator in dark brown or cognac tones: the natural texture of the leather dialogues with the iridescence of the mother-of-pearl without creating visual conflicts, and the patina that develops over time adds character to the wrist. Alternatively, a smooth black or graphite grey calf leather offers a more versatile and understated option, perfect for those seeking an elegant strap for professional settings. For those who change straps often, a canvas NATO or FKM rubber strap guarantee practicality without compromising aesthetic coherence.

To change the strap on an Omega Aqua Terra 30mm, you must use a specialized tool (spring bar tool) that allows you to release the elastic pins that secure the strap to the case lugs. Position yourself in a well-lit area and place the watch on a soft surface to avoid scratches. Insert the tool into the lug cavity, gently apply leverage to release the pin, remove the used strap, then insert the new one by aligning it correctly before snapping the pin back into position. If you are unsure, the Casati Milano atelier offers replacement services with specialized staff.

Yes, any aftermarket strap with a 20mm lug width is theoretically compatible with your Omega Aqua Terra 231.28.30.20.55.002, provided it respects the aesthetic proportions of the 30mm case. However, we advise against combinations that conflict visually: for example, an overly thick strap could appear disproportionate on a compact case. Milano Straps offers a selection of 20mm artisanal straps that maintain stylistic coherence with this category of elegant watches.

The lifespan of a leather strap depends on usage, the quality of the tanning, and exposure to sweat and humidity. An artisanal alligator or calf leather strap with vegetable tanning can last between 3 and 7 years with average daily wear and careful maintenance (regular cleaning with a damp cloth, storage in a dry environment). If the strap is used occasionally or during alternating seasons, longevity can be extended. The Casati Milano atelier offers an 18-month warranty on all made-to-measure straps, during which any tanning defects are covered.
