Strap for Seamaster Aqua Terra 150M Co-Axial 30 Red Gold / Diamond / MOP / Bracelet

The lug width is 20mm. This dimension is specific to this model and represents the internal distance between the two lateral lugs of the case. To verify it with precision, use a digital caliper positioned between the lug shoulders on both sides.

For this rose gold 30mm case, we recommend alligator in cognac, dark brown or black tones, which enhance the warmth of Red Gold. For daily versatility, honey-colored vegetable-tanned calf or sport rubber straps represent concrete alternatives. The choice depends on the context of use and the patina desired over time.

The procedure requires specific tools: removal of the spring bar with a dedicated tool. Insert the pin of the spring bar extractor under the spring, compress slightly to release the pressure, then pull out the strap. Repeat on the opposite side. The reverse operation involves positioning the new strap, compressing the spring bar and reinserting it into the seat. If unsure, contact an authorized Omega center or an experienced watchmaker.

All straps with 20mm lug width are compatible. On milanostraps.it you will find a specific collection of artisanal straps in alligator, calf, shell cordovan and technical fabrics, customizable in size, initials and thread color. The Casati Milano atelier also offers the possibility of completely custom creations by appointment.

A quality alligator or calf strap, with vegetable tanning, typically lasts 3-5 years with daily wear, depending on exposure to sweat, moisture and sunlight. The leather naturally develops a patina that communicates the time lived. Sport rubber or technical fabric straps have longer durability (5-7 years) but less aesthetic aging capacity. Periodic maintenance with specific conditioners significantly extends useful life.
