Wears Big
Color: Black/Black/Blue
Watch wears a lot large than it stated size. Feels more around the 45mm dimension on the wrist.

Timex for bigger wrists

Looks great and fits my bigger wrist. I was not quite sure about the white dial but it looks better in person. Fast delivery. Thank you

Looks and feels great...if it only kept running...
Color: Black/Black/Blue
Looks great, feels great...Stopped running about 1 month after purchase. Timex wanted me to send it back (my cost) so they could fix it. I passed. Bought extra coverage, said it was still under manufacture warrantee. Learned my lesson...no more Timex watches.
