Frequently asked questions

What is the lug width of the Omega Globemaster 130.23.39.21.02.001?

The Omega Globemaster 130.23.39.21.02.001 requires a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 20mm. This width is the standard for this 39mm model and is compatible with the vast majority of aftermarket straps in leather, rubber and fabric available on the market.

Which leather strap should I pair with the Globemaster steel and yellow gold?

For the 130.23.39.21.02.001 we recommend a dark brown <a href="/pages/termine-glossario/alligatore">alligator</a> or a <a href="/pages/termine-glossario/concia-vegetale">vegetable-tanned</a> natural leather strap. Alligator emphasizes the richness of the case materials, while vegetable-tanned leather enhances the vintage-modern aspect of the clous de Paris dial. Avoid overly glossy leathers that compete with the steel-gold contrast.

How do I change the strap on the Globemaster 130.23.39.21.02.001?

The Globemaster uses integrated <a href="/pages/termine-glossario/deployante">deployante</a> clasps cast into the case. To remove the original bracelet, you need to open the case back and unscrew the pins from the inside. We recommend entrusting this to a specialized workshop or the Casati Milano atelier, which performs replacements with watchmaking precision.

Can I mount an aftermarket compatible strap on the 130.23.39.21.02.001?

Yes, any strap with a <a href="/pages/termine-glossario/misura-ansa">20mm lug width</a> is compatible. However, given the complexity of the integrated attachment system in the case, it is advisable to use a professional workshop. The 20mm straps available on Milano Straps are tested for compatibility with the Globemaster.

How long does a leather strap last on the Globemaster?

A quality leather strap (alligator, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a>, vegetable-tanned calf) lasts on average 4-6 years with ordinary maintenance. Exposure to sweat, water and UV rays accelerates aging. The Casati Milano atelier provides straps with an 18-month warranty and offers extensive maintenance services.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
