Strap for Seamaster Aqua Terra 150M Master Chronometer 41 Stainless Steel / Blue / NATO / Shaun White Edition

The lug width of this model is 20mm. This value represents the horizontal distance between the strap attachment pins on the case. It is essential to ensure compatibility with aftermarket straps and to prevent lateral wobbling during use.

The ideal strap depends on use: for urban versatility, alligator or shell cordovan in natural tones; for formal settings, matte-finished calf leather; for fidelity to aquatic heritage, black vulcanized rubber. On milanostraps.it you will find all 20mm options, customizable in length and details.

Use a spring bar tool (small fork-shaped extractor) inserted under the pin from inside the case. Applying controlled pressure on one of the two sides, the pin will retract allowing you to remove the old strap. Repeat the operation on the other side. For installation, align the pins with the slots of the new strap and press until the safety click.

Yes, if the lug width is exactly 20mm. Compatibility does not depend on the strap brand but on the exact pin width. Always verify that the pin is standard Omega (typically 1.1-1.2mm). Handcrafted straps from milanostraps.it guarantee construction precision and certified compatibility.

A handcrafted strap in vegetable tanning or alligator leather lasts an average of 3-5 years with daily use, developing natural patina that amplifies aesthetic value. Shell cordovan resists for 6-7 years. Durability depends on environmental humidity, cleaning frequency, and tanning quality. Casati Milano offers an 18-month warranty on all custom-made straps.
