Strap for Seamaster Aqua Terra 150M Co-Axial 44 Chronograph Stainless Steel / Red Gold / Grey

The Omega Aqua Terra 231.23.44.50.06.001 has a lug width of 20 millimetres. This corresponds to the outer diameter of the suspension pins that connect the strap to the case. Measuring the lug width precisely is essential to ensure perfect compatibility with a new strap.

For the Omega Aqua Terra 231.23.44.50.06.001 in steel and red gold, we recommend alligator in brown or blue tones: the natural grain and patina over time enhance the nautical character and the bicolour nature of the case. Alternatively, vegetable-tanned calf offers versatility and authentic ageing characteristics.

To change the strap, you need to remove the suspension pins (20mm) using a dedicated tool such as a spring bar removal tool. Position the watch on a soft cushion, insert the removal tool into one of the lateral lugs and gently push the pin towards the opposite side until it comes out completely. Repeat for the second pin. Mount the new strap following the reverse procedure.

Yes, any strap with a 20mm lug width is mechanically compatible. However, we recommend artisanal straps made with rigorous manufacturing tolerances to ensure a superior wearing experience, minimal angular play and greater durability over time.

A high-quality artisanal leather strap (alligator or vegetable-tanned calf) lasts an average of 5-7 years with daily wear, provided proper maintenance: avoid excessive moisture, periodic cleaning and specific protective treatments. Leather develops a natural patina that imparts aesthetic character over time, transforming ageing into a narrative quality of the object.
