Great watch and fantastic value

I get so many compliments on my watch. Not only does it look great, it is so functional with my active lifestyle. Waterproof, sweat, dirt it takes it all. Love this watch.

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.
