Why these choices

Ostrich leg leather has a natural grain that adds interest without the formality of a polished hide, which fits the Alpinist's outdoorsy character. Dark gray is a neutral that works with the watch's green or cream dials and the steel case, so it stays flexible across outfits.

A stainless deployant clasp keeps the tail secured and makes the strap easy to put on, and it protects the leather from the bending a pin buckle causes over time. We matched it in steel to the case.

At 75/115 mm with an 18 mm buckle width, the strap suits a mid-size wrist and centers the Alpinist's case cleanly with a short tail.
