Strap for Seamaster Aqua Terra 150M Quartz 29.2 Stainless Steel / Silver / Bracelet

The lug width is 18mm. This measurement represents the distance between the two lugs (pins) that connect the case to the straps. An incompatible strap will not fit into the attachment points, so it is essential to verify this dimension before purchase.

It depends on usage and aesthetic preferences. For formal contexts, a cognac brown or black alligator amplifies elegance. For everyday versatility, a vegetable-tanned calf offers natural aging patina. For water activities, a cotton NATO or FKM rubber strap ensures waterproofness and durability.

Use a spring bar tool to gently compress the small springs (spring bars) that hold the strap to the lugs. Position the tool perpendicular to the lug, compress, and remove the old strap. Insert the new strap by aligning the pins with the holes, ensuring they enter completely until you feel the spring click into place.

Any strap with an 18mm lug width is compatible. Milano Straps offers a dedicated collection for this measurement, available in leather, alligator, shell cordovan, NATO and rubber, with customization options (sizes, initials, stitching thread) and warranty up to 18 months through the Casati Milano atelier.

A quality calf or alligator strap, with vegetable tanning or traditional tannage, lasts between 3 and 5 years of moderate daily wear. Factors such as humidity, sun exposure and frequency of wear affect longevity. Regular care (gentle cleaning, natural drying, occasional conditioning) significantly extends useful life.
