Water Resistant to 100 Meters
A Trail-Ready Classic
This update to our Expedition Sierra brings fresh appeal to a trail-ready classic with a 40mm brushed stainless-steel case and a unique camo-print khaki dial.

Luminant in-fill on the hands and stylized markers makes it as easy to read at midnight as it is at high noon. And with 100m water-resistant construction and a double-layered slip-thru fabric strap, it’s built to go the distance on your next adventure—rain or shine, mountain or valley, and everything in between.Specifications

Mineral Crystal
A toughened glass made from silica that's heat- and scratch-resistant, offering clear visibility and solid everyday durability.
Mineral Glass
Enhanced durability
Mineral crystals use a similar material to windowpane glass and were developed for watches as a harder alternative to acrylic. Mineral crystals are still susceptible to scratches but less so than acrylic, however it is not possible to buff out these scratches as it is with acrylic. Mineral glass is not as shatter resistant as acrylic but does offer greater transparency and clarity. Due to their improved scratch resistance versus acrylic, and improved shatter resistance versus sapphire, mineral is often considered to be the best of both worlds as a crystal material.
