FAQ
What is the lug width of the Armin Strom Gravity ST14-DE.90?
The Gravity ST14-DE.90 features a 20mm lug width. This dimension represents a deliberate geometric choice by the manufacture: it maintains impeccable optical proportions relative to the 43.40mm case and ensures comfort on wrists measuring 17 to 20 centimetres in circumference. Lug width is measured from the interior of one lug to the interior of the opposite lug, perpendicular to the spring bar axis.
Which strap material is most suitable for the Gravity ST14-DE.90?
Natural alligator is the most elegant choice, with a patina that evolves over time in perfect dialogue with the skeletonised bridges of the movement. Vegetable-tanned calf leather offers a uniform texture that amplifies the architectural aesthetic. Cotton NATO straps provide contemporary versatility, whilst rubber represents the pure technical solution for elemental resistance.
How do I change the strap on an Armin Strom Gravity ST14-DE.90?
Strap change requires extraction of the spring bar from the lateral lugs using a dedicated tool, available from most retailers. On skeletonised models such as the Gravity, it is advisable that the change occur on a stable surface to prevent damage to the visible movement. Milano Straps offers professional consultation and strap change at the Casati Milano Atelier by appointment.
Can I use third-party compatible straps with the Gravity ST14-DE.90?
Yes, all artisanal straps with a 20mm lug width are geometrically compatible. However, it is essential to select a strap of equivalent quality: a stainless steel 316L lug of this calibre deserves naturally tanned leather and flawless stitching. Milano Straps supplies carefully selected 20mm straps for construction quality and raw materials, eliminating the uncertainties of generic aftermarket solutions.
How long does a natural leather strap last on a Gravity like this?
A high-quality alligator or vegetable-tanned calf strap maintains structural functionality for 5–7 years of daily wear, with aesthetic evolution of the patina. Durability depends on ambient humidity, frequency of use and maintenance. Vegetable tanning develops a natural patina that records time elapsed, whilst alligator retains a soft lustre. To extend service life, it is advisable to allow the strap to rest between uses and periodically apply specific conditioning creams.
