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

The lug width of the 220.25.30.20.55.001 is 14mm. This measurement must be taken from the inner point of one spring bar to the other, excluding the terminals. Millimetric tolerance is essential, as the lug housing on this 30mm case is compact and requires precise fitting.

For the iridescent mother-of-pearl dial, we recommend dark brown alligator or burgundy shell cordovan to leverage the contrast with the Moonshine Gold. Ivory calf leather creates harmony with the pearlescent reflections, ideal for summer. For sports use, an FKM rubber strap offers moisture resistance without aesthetic compromises.

Remove the original strap using a dedicated spring bar tool, pushing from one side to release the terminal. Insert the new terminals into the lug housing, aligning the shoulders. On compact cases like this one, proceed carefully to avoid damage to the inner keeper. If you prefer, Casati Milano offers a strap-change service by appointment.

Yes, provided it is declared compatible with 14mm lugs. Milano Straps verifies each strap against original Omega molds to guarantee a perfect fit with no play. The key is to exclude generic straps: lugs that are too wide create a floating effect, while lugs that are too narrow damage the terminals.

A high-quality alligator or calf leather strap, with vegetable tanning, lasts 3-5 years under daily use with regular maintenance (light cleaning, avoiding prolonged moisture). Shell cordovan, being denser, can last up to 7 years. Milano Straps offers an 18-month warranty on all custom straps, with the option for restoration afterward.
