Strap for Seamaster Aqua Terra 150M Co-Axial 34 Stainless Steel / Red Gold / Diamond / MOP / Bracelet

The lug width of the 231.25.34.20.55.003 is 18 millimetres. This means the strap must have a maximum width of approximately 17.5 mm to fit correctly between the integrated lugs of the case. Always measure the space between the inner edges of the two lugs with a ruler to verify exact compatibility.

For this watch with a mother-of-pearl dial, straps in brown or burgundy alligator offer elegance without competing with the dial. A vegetable-tanned calf leather in hazelnut tone is perfect if you desire a patina that develops over time. For a more sporty approach, an anthracite grey or black rubber strap maintains the collection's versatility without chromatic discord.

The 231.25.34.20.55.003 features rigid integrated lugs with fixed spring bars. To change the strap, you must remove the spring bars with a specific spring bar tool: locate the small hole on the underside of each lug, insert the tool to compress the spring, and extract the bar. Install the new strap by aligning the holes and repeat the operation on the other side. If you lack experience, consult a watchmaker or Casati Milano atelier.

Yes, provided the aftermarket strap has an 18 mm width and is equipped with fixed spring bars compatible with the integrated lugs of the 231.25.34.20.55.003. On milanostraps.it you will find customizable artisanal leather, rubber and fabric straps, all tested for compatibility with this reference. Avoid straps with mobile lugs, which do not fit correctly.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts on average 5-8 years with daily wear and regular care. Longevity depends on sun exposure, perspiration, cleaning frequency and tanning quality. Casati Milano artisanal straps, made in premium leathers with vegetable tanning, come with an 18-month guarantee and can be restored at the atelier to extend their lifespan.
