Strap for Seamaster Aqua Terra 150M Master Co-Axial 30 Moonshine Gold - Diamond / Green - Diamond / Bracelet

The lug width is 14mm. This measurement is the distance between the two case lugs where the strap is attached. It is a standard for women's watches with cases around 30mm. Make sure to measure internally between the metal protrusions to confirm this before ordering a replacement strap.

Honey brown alligator is the preferred choice: the natural grain reflects light like Moonshine Gold, creating tonal harmony without monotony. For daily wear, vegetable-tanned calfskin in brown or black ages magnificently and develops patina over time. For dramatic contrast, black shell cordovan creates maximum visual impact.

Use a specialized spring bar removal tool to remove the spring bars (the small pins that attach the strap to the case). Position the watch on a soft surface, gently press the spring bar with the specialized tool to release it, then remove the old strap. Insert the new strap by aligning the holes at the ends, then reinsert the spring bar. If you lack confidence, consult a certified watchmaker or Casati Milano atelier for the change.

Yes, provided it is compatible with the 14mm lug width. Verify that the dimensions are precise: straps that are too wide or too narrow will compromise aesthetics and practicality. Milano Straps artisanal straps are crafted specifically for this measurement, ensuring perfect compatibility and superior construction quality compared to generic straps.

A premium leather strap (alligator, shell cordovan, high-quality calfskin) lasts 3–5 years with moderate daily wear, depending on climate, frequency of wear, and maintenance. Vegetable tanning ages more slowly than other techniques and maintains structural integrity longer. Periodic maintenance—cleaning with a damp cloth, avoiding prolonged direct sun exposure—significantly extends the strap's useful life.
