The Globemaster 130.30.39.21.03.001 (aka: 13030392103001), seen from the bench

The Omega Globemaster model 130.30.39.21.03.001 represents the pinnacle of Swiss watchmaking precision. Launched in 2015 as an evolution of the legendary Constellation, this 39 mm case combines tungsten and stainless steel with a 13.7 mm thickness. The Omega 8900 co-axial movement features anti-magnetic silicon hairspring, Master Chronometer certification with ±0.3 seconds daily tolerance, and 60-hour power reserve. It displays hours, minutes, seconds, and date window through a sapphire caseback. The 20 mm lug width is specific to the Globemaster's integrated tungsten case design.

Frequently asked questions

What lug width does the Omega Globemaster 130.30.39.21.03.001 have?

The Globemaster 130.30.39.21.03.001 is equipped with a 20-millimetre lug width. This measurement requires a strap with a maximum width of 19.5–20.5 mm to ensure precise fit to the integrated tungsten lugs of the case. It is essential to measure the lug width accurately to avoid mismatching errors.

What is the best strap for the Omega Globemaster tungsten?

For the Globemaster 130.30.39.21.03.001, alligator leather in vegetable tanning represents the most harmonious pairing: the natural texture of Nile crocodile dialogues with the raw material of tungsten. Alternatively, shell cordovan develops a fascinating patina over time, while FKM rubber guarantees sporting practicality without aesthetic compromise.

How do I change the strap on the Globemaster 130.30.39.21.03.001?

The Globemaster uses integrated lugs in the case. To change the strap, you need to remove the spring bars using a dedicated extractor tool. We recommend entrusting this task to an experienced watchmaker or the Casati Milano atelier to avoid damage to the tungsten case.

Can I fit an aftermarket strap to my Omega Globemaster?

Yes, 20-millimetre aftermarket straps are fully compatible with the Globemaster 130.30.39.21.03.001. Milano Straps offers a selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> in fine leather, rubber and fabric, customizable according to your preferences for colour, initials and stitch thread.

How long does an alligator leather strap last on a watch like the Globemaster?

A high-quality alligator leather in vegetable tanning lasts an average of 3–5 years with daily wear, depending on the frequency of exposure to moisture and perspiration. The patina that develops over time imparts charm, but natural fibre wear accelerates ageing after the fourth year. Milano Straps offers an 18-month warranty on all handcrafted custom-made straps.
