Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Stainless Steel / Silver-Waves / Bracelet

The lug width of the 220.10.38.20.02.002 model is 19 millimetres. This measurement represents the horizontal space between the two case lugs where the strap is inserted. Always verify compatibility by measuring your current strap or contacting Milanostraps via WhatsApp before purchasing.

For this 38mm Aqua Terra we recommend black or brown alligator for formal occasions, vegetable-tanned calf for everyday versatility, navy blue shell cordovan for luxury with patina development. FKM rubber is ideal if you frequent marine environments. Avoid raw synthetic materials that do not age with dignity.

Use a dedicated spring bar tool to remove the spring bars that secure the strap to the case. Position the tool in the bar slot, apply gentle pressure to compress it, remove the old strap. Insert the new strap ensuring the spring bar locks securely in both seats. Verify the lock by attempting to move the strap: it should not slip.

Yes, any strap with a nominal 19mm lug width is compatible. Milanostraps stocks leather, fabric and rubber straps certified for this dimension. Always verify that the strap features correct spring bars (standard 19mm) and that the seat width is compatible with the Omega lugs.

Durability depends on the material and usage. Alligator and shell cordovan, if properly maintained, last 4-6 years of daily wear before requiring restoration (softening and conditioning). Vegetable-tanned calf varies from 3-5 years. FKM rubber offers 2-3 years before showing signs of deterioration. Casati Milano offers an 18-month warranty on every strap produced in our atelier.
