Strap for Tourbillon Gravity Air

The Armin Strom Gravity TI14-TA.M.50 features a 20mm lug width. This measurement is the distance between the two pins that connect the case to the strap. All straps compatible with a 20mm integrated lug attachment will fit this model perfectly.

For the Gravity TI14-TA.M.50, we recommend genuine alligator leather or vegetable-tanned calf. Alligator maintains aesthetic coherence with the brushed stainless steel case, developing natural patina over time. Vegetable-tanned calf offers an elegant, supple alternative. Both materials reflect the technical and understated DNA of the watch.

Strap change is performed using a spring bar tool (also called a strap removal tool) inserted into the small hole of the tension spring located on the inside of the case lug. Apply light, consistent pressure to release the pin from one side, then completely remove the previous strap. Insert the new 20mm strap, aligning the pin and allowing the spring to reposition automatically.

Yes, absolutely. Any artisanal strap with a 20mm lug width is compatible with the TI14-TA.M.50. Choose specialised brands that produce authentic materials—alligator, vegetable-tanned calf, or premium rubber. Always verify that the width is precisely 20mm.

Longevity depends on usage and care. An alligator or vegetable-tanned calf strap typically lasts 3–5 years with daily wear, thanks to the material's inherent durability. Replacement frequency increases if the watch is frequently exposed to water or humidity. Periodic maintenance with specific balms significantly extends the strap's useful life.
