Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Stainless Steel / Sedna Gold / Silver / Bracelet

The lug width of the Omega Aqua Terra 220.20.34.20.52.001 is 16mm. This measurement is calculated in proportion to the 34mm case and determines the width of the compatible strap. You can verify it by measuring the distance between the centers of the two lugs on the case with a digital caliper.

The Omega Aqua Terra 220.20.34.20.52.001, thanks to its two-tone case in Sedna Gold and steel, pairs beautifully with alligator, vegetable-tanned calf leather, and shell cordovan. Alligator emphasizes refinement; calf leather offers daily comfort; shell cordovan guarantees moisture resistance with a patina that evolves over time.

To change the strap, use a spring bar tool or contact a professional. Position the tool under the metal pin that connects the strap to the case, apply light pressure to release the pin, then remove the old strap. Insert the new strap by aligning the holes at the ends and reinsert the pin until it clicks into place.

Yes, any strap with a 16mm lug width is compatible with the 220.20.34.20.52.001 model. Custom artisanal straps available from Milano Straps can be personalized in leather, color, initials, and stitching thread, ensuring a precise fit and aesthetic coherence with your watch.

A quality leather strap with vegetable tanning typically lasts 3–5 years of daily use. Durability depends on the material (alligator and shell cordovan last longer), care, and frequency of use. Milano Straps straps include an 18-month warranty and can be refurbished at the Casati Milano atelier.
