Frequently asked questions

What is the exact lug width of the Steinhart Aviation A0707?

The Steinhart Aviation A0707 features a 24mm lug width, measured between the inner edges of the lugs. This specification is standard across the entire Aviation line and is compatible with any aftermarket strap designed for 24mm lugs.

Which strap is best suited for the Steinhart Aviation A0707?

We recommend a vegetable-tanned leather strap with substantial thickness (1.4–1.6mm) in antique brown or tortoise grey for the A0707. This choice reinforces the watch's aviation heritage. Alternatively, a nylon NATO or quality vulcanised rubber offer practicality for operational environments.

How do I change the strap on my Steinhart Aviation A0707?

Remove the watch from your wrist. Using a spring bar tool, gently push the small pin (spring bar) inward on one lug to release it. Repeat on the other side. Insert fresh spring bars into the new strap, then hook both ends onto the watch lugs with light pressure until you hear a click.

Can I use an aftermarket strap on this model?

Yes, any strap sized for 24mm lugs is compatible with the A0707. Verify that the strap includes suitable spring bars and that its thickness does not interfere with the deployment clasp. Milano Straps curates a selection of 24mm straps specifically chosen for this timepiece.

How long does a natural leather strap last on a watch like the Steinhart Aviation A0707?

A quality leather strap with vegetable tanning and at least 1.4mm thickness typically lasts 3 to 7 years depending on use and maintenance. Factors such as perspiration, humidity, sun exposure, and frequency of wear influence longevity. Regular care—cleaning and conditioning with natural wax—significantly extends strap lifespan.
