FAQ
What is the lug width of the Armin Strom Gravity ST14-TE.M.90?
The lug width of the ST14-TE.M.90 is 20mm. This dimension is proportionate to the 43.40mm case diameter and permits the use of a comprehensive range of compatible artisanal straps. To verify conformity, measure the internal distance between the two lugs of your watch using a digital calliper.
What is the best strap for the Armin Strom Gravity ST14-TE.M.90?
The selection depends upon intended use and aesthetic preference. For formal wear: alligator with vegetable tanning or black shell cordovan, which reflect the technical sophistication of the ATM13 calibre. For versatility: taurine calf in grey or chocolate brown. For sport and humid environments: vulcanised rubber or technical NATO strap. Consult Milano Straps' stylist for comprehensive personalisation.
How do I safely change the strap on the Gravity ST14-TE.M.90?
The Armin Strom Gravity employs spring bars. Utilise a springbar tool to gently elevate the internal locking mechanism of each lug, extracting the bar from its seat. Position the new strap by aligning the apertures with the lugs, then reinsert the bars sequentially. Verify that the bar is fully seated in the lug before wearing the timepiece.
Which aftermarket straps are compatible with this model?
All straps with a 20mm lug width are compatible with the ST14-TE.M.90. Milano Straps curates a selection of straps in alligator, calf, shell cordovan, NATO and technical rubber for this specific width. Consult the 20mm collection to view all available options, organised by material and finish.
How long does a leather strap last on a watch with a movement like the ATM13?
Strap longevity depends upon frequency of use, climatic conditions and material quality. An alligator or taurine calf with vegetable tanning from a specialist craftsman typically endures 3–5 years with daily wear. Shell cordovan, owing to its superior fibre density, may reach 6–8 years. The patina that develops over time represents an element of distinctive beauty, recording your lifestyle upon the watch.
