Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Stainless Steel / Sedna Gold / Grey-Waves / Alligator

The lug width of this model is 19mm. This is the internal distance between the fixing pins that pass through the strap. To verify it correctly, measure with a caliper the distance between the two metal pins, not the total width of the original strap.

We recommend dark-toned alligator to enhance the Sedna gold, fine-grained French calf for daily softness, or shell cordovan for those desiring natural aging. Rubber remains a practical choice for humid environments. The 38mm case combination requires structured straps that do not yield to the weight of the two-tone case.

Omega uses fairly robust lugs: insert a spring bar tool under the metal pin, gently lift to release the pin, and remove the strap. Repeat on the opposite side. Installation of the new strap is performed in reverse sequence. If you prefer to avoid DIY, Casati Milano offers strap change with adjustment service.

Any strap with a 19mm lug width is compatible. On milanostraps.it you will find a complete collection of artisanal leathers, technical fabrics and rubbers, customizable in length, initials and stitching color. For bespoke experience, the Casati Milano atelier creates custom straps with direct leather selection and updates via WhatsApp.

A quality leather strap (alligator, calf, shell cordovan) lasts an average of 18-36 months with daily use, depending on the frequency of exposure to moisture, sun and mechanical stress. The Casati Milano atelier offers an 18-month warranty on all artisanal straps. Durability increases with vegetable-tanned leather that develops protective patina over time.
