Strap for Seamaster Aqua Terra 150M Master Chronometer 41 Stainless Steel / Blue / Bracelet

The lug width of this model is 20mm. This dimension represents the space between the pins that connect the strap to the case and is essential to ensure compatibility with aftermarket straps. If you wish to verify manually, measure the distance between the two horizontal holes on the case where the original strap pins are inserted.

The choice depends on the intended use of the watch. For an elegant setting, we recommend a dark brown or cognac alligator strap that harmonizes with the Teak dial. For everyday wear, vegetable-tanned calf leather offers natural patina and versatility. For water activities, a quality rubber strap ensures durability and practicality. A NATO strap offers maximum interchangeability and casual style.

To change the strap, remove the connecting pins using a specific tool (spring bar tool) or consult a professional watchmaker. Insert the tool into the small opening of the pin, gently lever outward and the pin will pop out. Repeat on the other side. Then insert the pins of the new strap into the same holes, applying gentle pressure until they click into position. It is a simple operation, but if you wish to avoid any risk, entrust it to a professional.

Yes, completely. With a standard lug width of 20mm, you can pair it with any quality artisanal strap with the same dimensions. Aftermarket straps offer the opportunity to personalize the watch according to your personal style, without compromising on compatibility. Online you will find a wide selection of 20mm straps in leather, rubber and fabric.

A high-quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years under normal use conditions, varying based on frequency of use, sun exposure and humidity. A rubber strap has a longer lifespan, up to 7-10 years. Regular maintenance – avoiding prolonged salt water exposure for leather and protecting from intense UV rays – significantly extends useful life. Straps with artisanal warranty offer additional protection and replacement options in case of defect.
