I am sure the resin is durable, but...
Color: Black/ Green
With the resin & acrylic face, it just feels way too light & concerning it will be easy to damage. Went with a metal case Expedition.

Pleased overall with one caveat
Color: Black
Handsome watch, enjoy and often use the Indiglo feature, silicone band extremely comfortable. Only negative for me is the access to replace the battery is unnecessarily complicated requiring a special tool versus other Timex models. Pleased with my purchase, overall.
