FAQ
What is the lug width of the Armin Strom Gravity ST13-GW.50?
The Armin Strom Gravity ST13-GW.50 features a lug width of 20mm. This dimension, measured between the two attachment pins of the case, is essential for strap compatibility. Always verify the measurement before purchasing an aftermarket strap.
Which strap is most suitable for the Gravity ST13-GW.50?
For the Gravity ST13-GW.50, we recommend an alligator strap with vegetable tanning for formal occasions, or a leather strap with straight grain for versatile daily wear. If you seek absolute durability, a NATO strap in high-density fabric or an FKM rubber strap guarantee longevity without maintenance. Your choice depends on your lifestyle and intended usage.
How do I change the strap on my Armin Strom Gravity ST13-GW.50?
To change the strap, you need to remove the attachment pins at the case ends. Use a mechanical spring bar tool, position it beneath the pin, apply gentle pressure and the pin will release. Insert the new strap by aligning the pins with their seats and press until you hear a click. If uncertain, contact Casati Milano atelier for professional replacement.
Can I use compatible aftermarket straps with the Gravity ST13-GW.50?
Yes, absolutely. The Gravity ST13-GW.50 accepts all straps with 20mm lug width. Milano Straps offers a comprehensive selection of artisanal leather, NATO and rubber straps compatible with this width. Always verify dimensions before purchase and review the technical details of each product in our catalogue.
How long does a leather strap last on an Armin Strom Gravity ST13-GW.50?
The lifespan of a leather strap depends on material quality, frequency of use and maintenance care. An artisanal alligator strap with vegetable tanning maintains structural integrity for 3-5 years under daily use. Calf leather typically shows visible wear (creasing, cracking) around 2-3 years. To extend longevity, avoid prolonged moisture and periodically apply natural oils specifically formulated for leather. NATO or rubber straps have virtually indefinite durability, dependent only on mechanical wear of the stitching.
