Strap for Seamaster Aqua Terra 150M Co-Axial 43 GMT Red Gold / Grey / Bracelet

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of this model is 20mm. This dimension is standard for many medium to large Seamaster Aqua Terra watches, facilitating the search for compatible aftermarket straps.

For a Red Gold Aqua Terra, the recommended materials are: dark brown or cognac <a href="/pages/termine-glossario/alligatore">alligator</a> (warm contrast), bordeaux <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> (elegant natural patina), vegetable-tanned <a href="/pages/termine-glossario/concia-vegetale">vegetable-tanned</a> calf (sustainable philosophy) and dark blue or black rubber (sporty versatility).

The lug width should be measured on the inside of the watch, between the two horizontal flanges where the strap attaches. For the 231.50.43.22.06.002 model, use a digital caliper or millimetre ruler, measuring from inside to inside: the result should be 20mm. Do not confuse this with the total length of the strap.
